A distinctive feature of Protherm is the availability of services throughout the country. Service is carried out both by our own specialists and with the involvement of specialists from partner companies.
By installation method:
- wall-mounted (installation is provided in a niche);
- mounted;
- floor-mounted (the boiler is installed directly on the floor covering - this is considered the best option for private homes).
Device
All models of Proterm boiler equipment consist of the following main components:
- Heating elements. Heating elements of medium and high power models consist of several elements (blocks). Three-phase ones consist of three single-phase ones. For each phase it is necessary to install a separate voltage relay (to prevent phase imbalance).
- Electronic control unit. Includes intermediate relay, fuses, terminal clamps, power supply, etc.
- Din rail. On which modular equipment is installed: relays, differential circuit breakers or RCDs, voltage stabilizers and grounding is connected.
- Circulation pump. To pump coolant into the system and maintain operating pressure in the circuits.
Important! The pump is built into the boiler body. All connections and adjustments are made by the manufacturer, so it is also covered by the manufacturer's warranty.
- The device housing, in which all components are installed, power wires and heating pipes are connected.

Equipment automation
Automation and instrumentation are designed to monitor and prevent emergency situations during operation of Proterm boiler equipment.
The equithermal temperature measurement function allows you to save energy consumption depending on weather conditions: on warm days the boiler operates at minimum power, on cold days - at maximum load.
Electronics composition:
- Safety valve (to prevent overpressure in the system).
Anti-jamming device. - RCD. Protects people and animals from leakage currents when touching the body of a faulty device.
- Load regulator relay. When electrical appliances are connected to the household network, the relay automatically smoothly reduces the boiler power. When the network operation is normalized, the automation returns the device to normal operation.
- Temperature relay. When the temperature in the room drops to 8 degrees, the pump starts. For this function to work, you must connect an air temperature sensor.
- The control panel is equipped with a function for storing parameters and adjusting the boiler power. For medium models with several heating elements, operation in operating modes with reduced load is possible.
- Installation must be carried out in accordance with the instructions supplied with each model. Protherm recommends using the services of a professional service, because... In this case, the service and repair warranty will apply.
Important! When installing equipment yourself, damage to the housing is common, which can lead to a violation of warranty obligations on the part of the consumer.
- The installation location must be carefully thought out: boilers must be easily accessible for inspection and maintenance. Measuring instruments must be in a visible place.
- If a scheme with forced circulation, the boiler should be installed at the highest point of the heating system.
- When installing several boilers in a room, it is necessary to use a parallel connection.
- The cable cross-section, the power of circuit breakers and RCDs must be selected taking into account the power of the boiler and circulation pump.
- The house must be grounded type TN-C-S or TN-S; heating system devices must be grounded.
For the device to operate correctly, it must be configured correctly:
- Connect the boiler to the household electrical network.
- Set the temperature of the heating system.
- Set operating parameters of pressure and power.
- Start the equipment. If there are no failures in the operation of the unit within 3 days, the installation is considered successful.

Question: I recently noticed that the voltage stabilizer clicks, after which the boiler starts to work unstably, what could this be?
Answer: This is not about the boiler. The stabilizer clicks because the relay is triggered when the voltage drops in the network, a short time breaks the phase - it’s because of the phase break that the boiler may behave unstably.
Question: I have a Protherm KLZ 50 gas boiler with a turbocharger. A problem has arisen - a stain has appeared on the firebox, and it is gradually increasing all the time. They called local specialists and said that usually no one addressed such problems.
After a few more calls, a specialist (chief engineer) finally arrived and adjusted the gas supply to the boiler - after which the boiler began to work with modulation (that is, first at low speed and then at full speed). Before this, it was always turned on at full power and threshed without stopping in cold weather. This was during the heating season of 2013 and the stain stopped growing. This year the entire spot began to grow again. What to do?
Answer: If the burner insulation is not damaged, the stain will not affect the safe operation of the equipment.
Question: Maybe the boiler cycles frequently and consumes a lot of gas because the boiler power is too high? I have S=220m2, power=38 kW. I took this power with the prospect of heating the garage. If this is so, then what should I do to stabilize the operation of the boiler and gas consumption?
Answer: Definitely. We need to reduce the power. Not to the minimum, but proportionally.
Question: Tell me: I’m planning a Cheetah 25K boiler and BKN Proterm B100Z. Are additional three-way valves and pumps needed?
Answer: The three-way valve and pump are already built into the boiler. All you need is a boiler sensor.
Question: what does a two-stage burner mean in relation to Grizzly 65 KLO: this is the notorious winter-summer mode (i.e. 1st stage - summer, second stage - winter) or minimum (1st stage) and maximum (2nd stage) boiler operation, which is normal It is set to maximum at the factory, there is no official information on the website, nor in the manual.
Answer: A 2-stage burner is an analogue of modulation, i.e. the boiler can operate at maximum power (2nd stage), maybe at a reduced one (1st stage) or turn off if there is no demand for heat at all. Moreover, both stages are adjustable.
Question: if the house is well insulated, then perhaps a 30 kW boiler will also operate. What does it have to do with when it’s cold - one power is needed, when it’s warmer - another, the temperature changes by 10-15 degrees during the day, from 0 to -15, etc. What then? Provided that you cannot regulate any boiler yourself, but call a specialist. Explain how to behave with this boiler?
Answer: if the house is well insulated, the likelihood of clocking is reduced. The house cools down more slowly, the coolant in the heating system also cools down less, the boiler sees this and does not operate at maximum power, but modulates only to maintain it.
Choose a boiler with maximum power that will cover the maximum heat demand of your home. There is no need to take a large supply (unless you plan to expand). Then the boiler will modulate, depending on the need - it gets warmer outside, the power decreases, colder - it increases.
Question: A Protherm 30 KLOM floor-standing boiler has been installed. The heating project is still under development; combined heating is assumed: radiators and heated floors. According to the instructions for the boiler, the power of the circular pump must be connected not directly to the socket, but through the boiler terminals, so that the boiler can turn off the pump at low temperatures and, as I understand it, therefore prevent corrosion of the cast iron. But for heated floors, it is assumed to use a heated floor with a mixing unit and another circular pump. When the main heating pump is turned off, the underfloor heating pump can still circulate through the boiler if it is plugged directly into the socket.
In this regard, 2 groups of questions:
1) It turns out that in order to preserve the boiler, it is necessary to hang both pumps on the boiler terminals? But in the instructions I did not find any explanations about this and the maximum power of the connected equipment. Is this possible, what is the maximum power and is it possible to see some link to
document allowing this?
2) In addition, ideally, I would like to connect the power to the heated floor pump through a thermostat installed in the room (turns on the 220V power when the temperature decreases and turns off when the temperature increases), to automate the regulation of the floor temperature. It turns out that this is basically impossible?
Answer: You cannot connect two pumps to one terminal. Proterm does not have such a control scheme. To control the TP there is cascade automation. SD2000 has been discontinued.
Question: I can’t find data on the pump power for this boiler, maybe you can help? For example, if we have one pump with a head of 4 meters, then it consumes 45 W, if it is 6 meters, then it consumes 80 W, if one pump is 8 meters, then it consumes 170 W. So why is it not possible to connect 2-3 pumps of 45-80 W each? What is the reason for this?
Answer: This is due to the fact that the manufacturer provides for connecting only one pump to the terminals. Connecting 2 or more is at your own risk.
Question: about connecting the B200S boiler to the gas floor-standing boiler Bear KLOM 30. The manual for the B200S says: To ensure the operation of the boiler with the PROTHERM boiler, an electromechanical three-way separating valve with a built-in electric
switching contact size DN ? (for use with wall-mounted boilers) or DN 1” (for use with floor-standing cast iron boilers).
The manual for KLOM says: The boiler control system regulates the heating of the boiler using a pump and an NTC boiler sensor. Nothing is said about a three way valve. It is not entirely clear which scheme is preferable? Which electromechanical three-way isolation valve with built-in electrical changeover contact is meant? Where can I see its characteristics? The principle of control is not yet clear circulation pump, does the boiler turn off the pump or change its performance?
Answer: These are two possible schemes connecting the boiler to KLOM - through a three-way valve and through pumps. In the first case, no pumps other than a circulation pump are needed, in the second - a three-way pump.
Question: Protherm slope - is it possible to operate it painlessly from a generator using a single-phase switching circuit?
Answer: Models 6K and 9K can operate from a mains voltage of both ~380V and ~220V, others only from ~380V.
Question: Is it correct to connect a floor-standing boiler? Bear KLZ 30 through a hydraulic separator to separate heating circuits (Conventionally 2 circuits, respectively tied to automatic temperature control). Another thing I ask is that in KLZ the heating circuit of the built-in boiler is already integrated and, logically, when the boiler pump is turned on, the boiler circuit pump will be turned off.
Accordingly, there is no circulation - the secondary circuits will work on themselves, that is, drive the cooled coolant until the boiler pump turns off and the boiler pump turns on. Or no
should I bother and install KLOM 30 and connect the boiler to the hydraulic arrow as a third circuit? Who will advise what?
Answer: Protherm does not have such recommended schemes, but it does not prohibit them. That is, they have the right to exist. This is a question of correctness. As for the schemes. I believe that you can do it both ways, there are two nuances: In the first scheme, if you forget to close the hot water tap, the heating system will cool down and freeze in cold weather. This will not happen in the second scheme. Boiler room dimensions. The second option requires more space.
Question: I installed a Skat 21 kW electric boiler, while studying the Installation and Operation Instructions for the boiler I found information that there should be a minimum distance above the boiler to the ceiling - 800 mm. What is this connected with, why is there such a gap? I did not find such a requirement in the instructions for the gas boiler. Is this specific to an electric boiler? In fact, I get about 400 mm. Is this a big problem?
Answer: 800 mm is required to replace the heating element, if you have 400 mm, then to replace the heating element you will have to remove the boiler, this will not affect the operation of the boiler.
Question: We have a Panther 25 kTV boiler connected, a week ago a specialist started it up. I woke up in the morning, the message error f68 is on, there is no such error in the book, what should I do? I'm trying to reset the reset error, the boiler starts up to a temperature of 32 and gives an error.
Answer: The problem is loss of flame. That is, either the boiler does not see the flame (see towards the ionization electrodes), or there really is no flame (see towards the gas - supply or gas valve).
Question: Problem, I have a Protherm KLOM 50 with a turbo nozzle, it worked for 1.5 years, it won’t start. When turned on, the turbo nozzle starts and the display shows current temperature coolant and the indicator flickers in the right corner and that’s it! What is this?
Answer: The turbo manostat may be stuck. If abnormally low Atmosphere pressure- reduce sensitivity.
Question: For a house S=100 m2, which is better, a floor-mounted or a wall-mounted boiler? taking into account the connection of heated floors in two rooms S = 16 AND 18 M2 AND THREE water distribution points. My choice fell on Proterm, but I don’t know which one exactly, please tell me?
Answer: The approximate power for your home is about 15 kW. They will tell you more precisely at design organization. As for the models, the main difference between wall-mounted and floor-standing boilers is, of course, dimensions and installation capabilities. They have different options for compatibility with thermostats. Mounted ones have more ample opportunities management. It is also important to decide whether it is a double-circuit boiler or a single-circuit boiler + boiler combination.
Question: A Proterm KLOM 40 boiler and turbo nozzle have been installed. I have been operating the boiler since December 2013... I monitored the operation of the boiler on visits in the morning and evening. I moved into the house in March and noticed a peculiarity. from time to time the boiler accelerates to 85 degrees at a set temperature of 60 degrees. Moreover, when the boiler accelerates to 85 degrees, the lower right mark flashes on the screen and the circulation pump does not vibrate (I can determine the operation of the pump connected to the boiler by placing my hand on it, otherwise you won’t hear it). after heating the boiler to 85, the pump turns on and the boiler goes into normal mode... it cooled down to 55, heated up to 65. What could it be?
Answer: the diode is blinking - the boiler is operating in the boiler water heating mode. Everything is in order - this is a program for protecting against bacteria in the boiler - short-term heating.
Question: how to determine the frequency of short-term heating? I read that when the water in the boiler is drawn in one burst, the boiler gives a stop command to the heating pump and, as a priority, heats the water in the boiler (a 200-liter boiler) and after heating the water in the boiler to nominal, it turns on the pump again to the batteries and since the boiler is in the error does not go away, which means the boiler automation does not find any violations. There are only two buttons on the boiler, and how smart it turned out to be.
Answer: This boiler does not have an antibacterial function in the boiler. This causes the boiler to heat up. Regardless of the water supply, when there is a request to heat water in the boiler, the boiler switches to heating the boiler at maximum power, which is why the temperature rises to 85. Heating
not active at this moment. As soon as heating of the boiler is completed, the boiler switches to heating. DHW is a priority.
Question: What is the difference (other than power) between the Gepard 23 MTV and Panther 25 KTV boilers? The sellers said that copper parts there is more in the Panther (the Cheetah is a cheaper Panther). So I want to understand what the fundamental design differences to decide whether it's worth paying more. What are their heat exchangers made of? When there is a temporary outage of gas and/or electricity, do both boilers start working automatically?
Answer: Structurally - different expansion tanks of 5 and 7 liters. Plus there is a difference in the design of the front panel. They are partly right, since the Panther is more powerful and has a larger heat exchanger. But in general, they are the same. in the event of a power outage/on, the boilers will turn on, if gas is turned on, both are in error, turning on after resetting the error.
Question: It is necessary to connect only BKN to the 30 KLOM floor stand. This boiler will only work to load the boiler. Accordingly, the entire system consists of a boiler, BKN, safety group, membrane tank and circulation pump. How to do it right? Just connect a temperature sensor and a boiler loading pump to the block or are there any nuances?
Answer: It is necessary to switch the boiler to “summer mode” for heating, then it will only work for the boiler. There are no other nuances.
Question: Tell me, is the Boiler installed? Protherm Cheetah, on low power The burner displays error 28 or 29. And it still does not maintain the set temperature (does not turn off after reaching the set temperature). Where to look, what to turn?
Answer: Your boiler probably has problems with the gas valve. Here I can only recommend an examination by a specialist.
Question: They installed a Bear KLS 40 boiler for me. It started normally, no one lives in the house yet, but I left the boiler on. 2 days later I arrived, the boiler was stuck with error F1. I reset the error, it starts, but at different intervals it throws f1 again. Could this be from
for insufficient ventilation?
Or dig towards electricity? The voltage seems to be stable, but in any case I will
install UPS And the second question is which gsm module is best to install on my protherm to control the boiler via SMS? Is it possible to reset errors via SMS? The phasing is observed, the hot water boiler is not filled and not turned on.
Answer: This error means that the automatic ignition is blocked and the gas supply through the gas valve is stopped, i.e. loss of flame. Such a blockage can occur in cases where, being in the open gas valve mode, the ignition automatic system does not receive a feedback signal about the presence of a flame from the ionization electrode.
This malfunction can also be caused by the activation of the emergency thermostat or combustion products thermostat. Low gas pressure at the inlet, incorrect electrical connection (phase and zero are reversed) can also cause loss of flame. If the fault cannot be resolved using the RESET button, contact your service organization. Regarding GSM, Proterm does not have such modules.
Question: It turns out that the modulation should work and the boiler will maintain a stable temperature with a water flow of 3 l/min? We will observe in practice. Well, it is clear that if the heat exchanger is clogged, there will be no normal heat exchange and water flow. We are talking about how the new boiler should work and whether there are gas adjustments for the DHW, i.e., the ability to reduce the power of the DHW so that the boiler does not cycle at low pressure in the water supply.
Answer: After switching on, the modulation should maintain a stable temperature. There are no gas adjustments for DHW. Automation itself regulates the operation of gas fittings.
Question: The SO10045 sensor for connecting a boiler is a thermal resistance. The thermostat performs a similar function. Why is a sensor needed to connect the boiler and boiler?
Answer: the principle of operation is similar, but when operating from a thermostat, the boiler does not receive information from the boiler about the water temperature, therefore it is not able to modulate the heating power, but only turns on at full power and turns off, which is not economical. Plus, when using SO10045, the current temperature in the boiler is displayed on the boiler - convenient and clear.

Questions to representatives of the Proterm company
Question: Gas floor-standing boiler protherm. It is necessary to convert 85 clo from connecting the boiler through a three-way valve to connecting the boiler through a pump. I understand that replacing the board solves everything, but still?
Answer: To the 85th KLO, the boiler must initially be connected via a pump. See electrical diagram. PLO is connected through the boiler.
Question: A Protherm Medved KLOM 40 floor-standing double-circuit boiler and a turbocharger have been installed. The instructions for the boiler indicate that when connecting the turbo nozzle, it is necessary to bridge the terminals of the combustion products thermostat. This thermostat, as I understand it, is installed under the chimney. How to bridge it and is it necessary to do so? The specialist started the device, but didn’t even remember about this sensor. Which room regulator should I connect? Any or there is some kind of trick. Is there a regulator for this model with two pairs of contacts?
Question: Proterm Skat. There is a diagram of the operation of this boiler for domestic hot water through a three-way and NTS sensor. For example, I have an electric boiler of 9-12 kW, I need only 6 kW for heating. I, of course, soul it from the settings panel to the necessary level. But when switching to DHW heating how much will it consume? Are the power settings saved for both DHW and heating? Is it possible to supply, for example, 6 kW for DHW heating?
Answer: DHW power is not regulated (always full power). Your DHW does not work all the time. And at higher power, the boiler will heat the water faster. What is more economical, to heat longer with a weak device or faster with a powerful one, you have to look.
Question: which burner is suitable for the Proterm Bizon 35 NL boiler to operate on liquefied gas, or how much does it cost to reconfigure regular gas. burners to work on liquefied gas? And in general, what good/bad can you tell about this model, or would you recommend something else, since I decided to take a closer look at floor-standing cast iron boilers. It is necessary to reconfigure the BTG 3 burner for liquefied gas or installed it, failed
pipeline from a gas tank or cylinder and does it work?
Answer: No. This burner must have a valve of suitable dimensions to obtain proper ignition and smooth adjustment. The valves are selected for supply pressure, which is approximately 300 mm BC. I recommend checking the burner gas pressure using a water pressure gauge.
Question: I launched the Skat electric boiler, I was just about to buy Instat-2, but it was discontinued, it turns out that it was out of production. What do you recommend instead?
Answer: Take a closer look at Termolink S and SD 2000.
Question: I am choosing a double-circuit boiler. I settled on the Panther 25 KTV or turboTEC pro VUW (mini version). Questions have arisen: As far as I understand, the “COMFORT” function of DHW in Panther is an analogue of hot start in Plus. But while the Plus has two additional sensors for hot water, the Panther does not have them. How is the temperature maintained in the secondary heat exchanger of this device?
Answer: Hot start function. Operating principle: The burner turns on when the temperature in the primary circuit drops 30 °C below the set DHW temperature. The burner switches off when the temperature reaches a difference of 10 °C below the set DHW temperature. The ECO symbol will appear on the display when the set DHW temperature is below 50 °C.
Question: I have a Proterm Pantera double-circuit wall-mounted gas boiler with a bottled gas burner. During a cold start there is a strong humming noise. As the antifreeze warms up, the buzzing goes away completely. What could be the reason?
Answer: Cold and hot antifreeze different characteristics. Thus, while the antifreeze is cold, a humming noise may occur.
Question: could you tell me - I have a PROTHERM B200S boiler with a magnesium electrode, we started installing it, and a question arose. At the very top of the tank there is a valve with a diameter, if I'm not mistaken, 3/4 plastic with a thread, about 5 cm long, marked in the instructions as RC (recirculation). What is it for, what is connected to it?
Answer: This pipe connects to the DHW line - DHW recirculation.
Question: what are the specifics of connecting the Proterm B100S boiler to the TLO Bear non-volatile boiler? The water in the boiler coil apparently moves forcefully, and the heating system is supposed to have an EC, are these completely independent cycles?
Answer: if you connect the boiler according to a circuit with a feed pump, the boiler ceases to be energy independent, the board changes, and pumps are added. If through a 3-way valve, one pump will be needed, again the system ceases to be energy independent.
Question: Boiler gas Proterm Lynx has been operating since 2008. What is the service life of such a unit and is it possible to connect an indirect heating boiler to it?
Answer: Under operating conditions specified by the manufacturer, about 10 years (again, indicated by the manufacturer). Protherm does not provide the ability to connect BKN to Lynx. If you decide to try it, it is at your own risk.
Question: what is the difference between the wall-mounted boilers Proterm Gepard 23 MTV, Panther 25 KTV, Tiger 24 KTZ?
Answer: The Panther is slightly more powerful than the Cheetah (both in heating and hot water) + it has a different control panel. Tiger has a built-in 45 liter storage boiler, which increases the maximum DHW consumption.
Question: I am faced with choosing a gas boiler. Need heating and hot water. The house is about 165 square meters. Can you tell me what is suitable for me? And another question - are there boilers with side discharge, that is, there is no need to make a huge chimney and the discharge occurs immediately to the side through the wall? Do you have these? Another question: is it necessary to install a boiler? What does it give? And one more thing - it happens that the electricity goes out - will all this work without it or does everyone need electricity?
Answer: In terms of power and water consumption, gas, wall-mounted, double-circuit (heating + hot water supply), electrically dependent, with a closed combustion chamber (it is possible to vent combustion components to the side through the wall) are suitable for you. Boilers Cheetah 23 MTV, Panther 25 KTV, Tiger 24 KTZ, gas, floor-mounted, combustion, a boiler is additionally required for hot water supply. Bear 30 TLO is electrically independent. Bears 30 PLO/KLOM/KLZ -
electrically dependent, you can install (optional) the “Semi-turbo” extension, which will make it possible to divert combustion components to the side through the wall, but it runs on electricity.
Question: Boiler KLZ 30 Proterm Bear. Strange operation from the outdoor temperature sensor. T - 55 gr. C, curve - E5, the lower the air temperature, the hotter the house becomes, and vice versa, the closer to zero, the colder. So the temperature in the house jumps (with one setting mode) from 22 degrees. From up to 30. You have to constantly “play” with the temperature or curve. Is it possible to convert this boiler to wireless home sensors?
Answer: In the equithermal control mode, the temperature of the coolant in the boiler is regulated depending on changes in the outside air temperature. Therefore, you can only “play” here crookedly. Regarding sensors, there are no wireless regulators in the Russian Protherm catalogue.
Question: The KLZ 30 Bear boiler was installed in March last year, it worked well, now, when the air temperature drops, they increased the temperature to 80 degrees, the boiler goes out. gives error F1. It works fine up to 70 degrees, but when the temperature rises it goes out. We tried turning the gas supply adjustment wheel, but it didn’t help.
Answer: Try using the RESET button to reset the error; if the problem persists, you need to call the service, as you need to look for a problem in the operation of the ionization electrode, gas valve, etc.
Question: what is the reason for the limitation on the volume of coolant in the heating system when using the Protherm Lynx wall-mounted gas boiler (70 l.)? If the systems are assembled from steel pipes and cast iron radiators (works flawlessly for several years) on an area of 180 sq. m., clearly exceeding the maximum coolant volume, then what problems should we expect?
Answer: This is due to the capacity of the expansion tank in the boiler (5 l.).
Question: What kind of regulator can be connected to the Panther 25? The problem is that the boiler heats CO + heated floors (connected via a thermostat with a separate pump), now I took Protherm Instat Plus for testing, when it turns off the boiler, the pump drives over the heated floors cold water. I would like the temperature of the coolant in the boiler unit to drop by 5 degrees at night, the temperature in the house will drop and the warm floor will not cool down.
Answer: Protherm Instat Plus will cope with your task. (A programmable controller with a weekly and daily program allows you to set up to 6 different time intervals during one day. During these time intervals, you can set any temperature from the permissible temperature range). Thermolink Lux will also be able to adjust by day of the week and time periods.
Question: I need to not turn off the boiler, but reduce the temperature of the coolant in the boiler: example: from 65 to 61 at night, Thermolink Lux can do this, or as simply as Protherm Instat Plus off. boiler at the set temperature in the room?
Answer: Thermolink Lux is connected via eBus, it will regulate the boiler power.
Question: In the boiler operating manual indirect heating it is indicated that tap water it is heated by heating water. How can this boiler be used to prepare hot water in the summer when the heating is turned off? Where should such a boiler be placed: in the boiler room (five meters hot water line) or in the immediate vicinity of water supply points (bathroom) so that there is no
interruption in DHW supply? Is the second option technically possible?
Answer: If everything is designed and installed correctly, the water will be heated in the summer without heating. It doesn’t matter where to install it; in any case, there are options to organize the supply of hot water without interruption.
Question: The passport for the Panther double-circuit boiler indicates the maximum temperature in the heating circuit is 85 degrees, but only 75 degrees is set on the boiler. what is the reason? How to raise it to 85 degrees, otherwise when it’s frosty outside, the temperature in the house is above 18 degrees. doesn't rise.
Answer: The Panther has a maximum temperature of 80 degrees. Set by parameter d. 71.
Question: Are the thermostat contacts dry contacts? According to the documentation, the thermostat is 3-pin, i.e. can it be used as both NO and NC contacts?
Answer: Yes, you can.
Question: It is not clear about connecting the boiler to the network to provide protection against corrosion. In the description in Fig. 2, which shows the thermostat contacts?
Answer: You just need to connect the boiler to the network, there is a board inside, the anode is connected to it.
Question: The instructions mention a magnesium anode. As I understand it, it needs to be changed at some point. How it's done? Is it necessary to comply with any minimum distance between the ceiling and the boiler when mounted on the wall?
Answer: The power supply anode does not need to be replaced. The distance between the ceiling and the boiler is not regulated.
Question: Tell me what determines the minimum gas pressure at the nozzles of 1.1 mbar. on a panther 25 ktv 19v gas boiler? Why is setting a lower value not recommended?
Answer: At a pressure of 1.1 mbar, the boiler will produce the minimum power rating value, therefore, there is nowhere lower.
Question: can you tell me if the gas boiler Protherm 30 KLOM is phase independent?
Answer: The boiler is designed for connection to a single-phase three-wire electrical network 220 V 50 Hz with a protective conductor in accordance with the current PUE. It is not allowed to swap the “phase” (L–brown wire) and “zero” (N–blue wire) wires. Connecting the boiler to the electrical network is an intervention in internal organization apparatus. This work should only be carried out by a specialist.
Question: I have Proterm 30 KLOM. Tell me, how critical is a loss of voltage in the network for his brain? Does the boiler have sensors that will turn it off if there is no voltage in the network? How does overheat protection work? If it is critical, then how is it customary to deal with it?
Answer: The overheating protection function turns on the heating pump when the water temperature in the heating system, set by the user, is exceeded or if the temperature of the coolant in the boiler exceeds 85°C. If the temperature of the coolant in the boiler exceeds 90°C (fault F3), the boiler will automatically turn off. If there is a power outage, the device will turn off. When the power supply is restored, the boiler will automatically turn on, without losing the set operating parameters. If, after the power supply is restored, a fault message appears on the device display, unlock the boiler using the RESET button. Blocking of the boiler can occur due to its overheating as a result of stopping the pump after.
Question: The Proterm boiler has been in operation since October 2013. The boiler, heating and water supply systems were installed by local specialists. The heating system consists of 5 (40 sections) and a PVC pipe d=25mm with a length of approximately 40 m. I will try to describe the heating system: the boiler is installed on the 1st floor, from it a horizontal section of pipe is laid to the second floor, from this “riser” There are two horizontal sections: on the 1st and 2nd floors, on the 1st floor there are 2 radiators of 8 sections, on the 2nd there are 3 radiators of 6, 8 and 10 sections.
The water supply system consists of:
Pumping station - supplies water from a well (on/off pressure, respectively, 1/3.5 atm.);
- coarse filter;
- PVC pipe d=25 mm spread throughout the house (length approximately 10 m).
Problems with heating appeared 2 months after the system was launched, during which time the boiler heated both heating and water. (if it was set to 60 degrees, it warmed up to 65-68 degrees and turned off, turned on at 52-56 degrees, but now the setting is 75 degrees, and the temperature does not rise above 62 degrees; an interruption in water will heat up, and after It's been cold for a while). After installing the tech. servicing has not yet been carried out.
Answer: We need to look at the system’s hydraulics and gas supply. And these things require a specialist.
Question: How do the brains of the Proterm boiler react to a temporary power outage?
Answer: It shouldn’t, it will just turn on and that’s it. It may show an error - RESET is reset. If, in addition to shutdown, there are surges (without a stabilizer), then the board may be damaged.
Question: The boiler does not operate on a timer. How do you turn on the DHW saving mode on the timer?
Answer: You need to check whether the DHW temperature sensor is installed correctly and works correctly. Check resistance. Replace the sensor if necessary. In addition, check the functioning of the electronic board, DHW pump, etc.
Question: tell me, wall-mounted boiler Cheetah 23 turbo, underfloor heating system, area 80 square meters, plus one cast iron radiator(5 sections) in the boiler room. The temperature on the boiler is set to 60 degrees. Everything was fine. But a week ago it stopped heating to the set temperature - 54-55 and that’s it. I was guilty of the temperature being over 30 outside, but today it was 20 in the afternoon, and it still didn’t reach 60. Plus, the hot water supply began to work, but something was wrong - it flowed hot for 5 minutes, and then warm, although the device was working. What's happened?
Answer: Perhaps there was a drop in the gas inlet pressure and the unit stopped fulfilling its passport specifications. It is necessary to check the boiler settings, the condition of the hydraulics, etc. Such phenomena must be diagnosed on site.
Question: I have a Proterm Medved 40 KLOM boiler, the heating pump is connected directly to the electrical network, is this correct? and can I connect it directly to the boiler and what will this give me?
Answer: Connecting a heating pump to a separate machine may be related to local circumstances and the hydraulic circuit of the furnace. It would be more correct to connect the pump to the boiler so that the circulation of the coolant through the heat exchanger is controlled by the boiler’s automation and the device does not overheat.

If there is no possibility of connecting to the gas network, and solid fuel heating is not available, then an electric boiler becomes an alternative way to provide heat to the house. This article will introduce readers to Proterm Skat electric boilers, and also provide instructions on how to start them up.
Electric boilers Proterm Skat
This single-circuit equipment is made in a wall-mounted version. It is possible to connect a water heater. Most models three-phase mains connection required, but models with a power of 6 kW and 9 kW can operate from a 220 V network. The required level of hot water and heating temperature is selected using a display, which, by adjusting, helps control the operation of the equipment. Control is also carried out using a thermostat or sensor outside temperature.
To create a specific level of heat, the parameters are adjusted individually. Electricity supply is controlled remotely from the tariff meter. For domestic needs, you can install 24 kW and 28 kW units in a cascade.
Protherm Skat has:
- two-way pump;
- expansion tank;
- safety valve;
The Protherm boiler can also be connected via a voltage stabilizer. Electric boiler in action has a slow start, that is, for two minutes it “accelerates” and its power is minimal. The heating elements are protected from overload, their operation is uniform, this is achieved by being able to adjust the rhythm (1.2 or 2.3 kW).
Electrical Protherm boilers The ramps are distinguished by their low weight (only 34 kg) and convenient dimensions, making it possible to install them in almost any area. The operation of the boiler is reliably protected by several functions:
- protection against pump blocking;
- a pressure sensor that monitors the water pressure level;
- frost protection;
- protection against valve blocking and water heater freezing (when connecting a boiler).
If errors occur in the operation of the boiler, automatic diagnostics occurs, ending with the results being displayed in the form of a code. The decoding of the codes is given in the product operating instructions.
Advantages and disadvantages of electric boilers Protherm Skat
Proterm Skat has a number of advantages over other types of heating:
- does not produce harmful emissions into the atmosphere, since has no combustion products, therefore this type of heating can be called environmentally friendly;
- An electric boiler is an affordable type of heating. It is used where it is not possible to connect to mains gas or can become an alternative form of heating;
- does not require systematic maintenance, unlike, for example, gas or solid fuel models;
- silent operation;
- there is a heat level regulator;
- able to adapt to domestic water of poor quality;
- resistant to voltage surges;
- equipped with several types of protection.
Along with the advantages, there are some disadvantages:
- electric boiler Protherm Skat needs to be connected through a stabilizer;
- is unable to perform its work during a power outage.
Consumer Reviews
Consumers note that Protherm Skat provided an opportunity where gas connection was problematic or completely impossible. When the power grid is stable, many people refuse to connect to gas, saving considerable amounts of money. In addition, an electric boiler is used in parallel with a gas unit, connecting them to a single heating system. This find allows you to significantly save money on resources, alternating them with each other during the heating season.
If you connect a water heater to Protherm Scat, consumers will have prospects for using hot water. Many people note the perfectly designed design of the boiler, which fits well into any room interior. It can be successfully installed in living rooms; thanks to its silent operation, it will not cause increased attention.
The disadvantages are that when using only an electric boiler, there are no alternative heating options when it turns off. Therefore, before purchasing a Protherm electric boiler, you should make sure that there are no problems with electricity. Experts recommend use a voltage stabilizer, to ensure normal operating conditions for the Protherm Skat boiler.
In addition, the increased energy consumption of an electric boiler causes negative emotions among the population, since paying bills takes a toll. If we compare the costs of gas and electric heating, the Protherm electric boiler is a little more expensive, with identical heating parameters. From the above, we can conclude that this electrical equipment is chosen by those who do not have the opportunity to connect to network gas, as well as by those who care about the environment and see it as a source of environmental consumption.
How to put the Protherm Skat boiler into operation?
To start the boiler, you must follow the instructions below.
When the pressure is low, the “bar” light starts flashing on the display. To correct the situation, add water to the system. If in this case the pressure decreases, then you need to contact a specialist.
If you need to stop the operation of the Protherm boiler for a long time, you need to disconnect it from the power supply and turn off the taps. If a stop is needed in winter, then The system must be drained of water to prevent freezing.
How to care for a Protherm electric boiler? Do not use abrasive or chemical substances. It is better to wipe the surface of the case with a damp cloth, and then dry the surface.
Any malfunctions are indicated on the display by an error code. The code numbers are located and deciphered in the product passport.
If serious problems occur, for example the heat exchanger is frozen or water is dripping from it, It is prohibited to turn on the electric boiler to the power supply. You need to wait for a specialist who will diagnose and perform high-quality repairs. Replacement of parts is carried out only using original spare parts.
So, dear readers, you have become acquainted with the alternative type of heating Protherm Skat. When gas and solid fuel If you are within reach or you are a stickler for cleanliness, an electric boiler can be a good help.
Assembly elements, installation and connection of the Skat Protherm electric boiler
Boiler components Skat Protherm
Pump
Manufacturer - Wilo
Power supply - 230V/50 Hz

Before filling and putting the Proterm Skat electric boiler into operation, you must perform the following steps:
Loosen the cap air valve pump
Loosen and unscrew the rotor shaft cap and use a flathead screwdriver to rotate the shaft.
If quite noticeable resistance is felt when the shaft rotates, it is necessary to dismantle the motor part of the pump.
After this, clean the entire stator or pump rotor of impurities.
Before removing the Wilo pump, make sure that the following conditions have been met:
The water temperature in the boiler unit has reached a safe value (40°C).
The boiler was switched off via the main switch.
The heating water inlets and outlets were closed.
The remaining water in the boiler was drained.
Wilo pump dismantling work:
Disconnect the connecting cable connecting the pump to the control board.
Remove the heating water pipe leading from the pump to the heat exchanger.
Disconnect the tube leading to the expansion tank.
Pull out the safety clip.
Loosen and unscrew the pump safety screws located at the bottom of the boiler.
After turning the pump slightly clockwise, remove it.
Safety valve
If the maximum permissible pressure value in the Proterm Skat boiler is exceeded, excess water will be drained through the safety valve. The valve response pressure is 3 bar. The outlet of the safety valve must be equipped with a suitable drain.
If it is necessary to remove the safety valve, do the following:
Wait until the water has cooled to around 40°C.
Disconnect the Skat Protherm boiler from the electrical network.
Close all valves located under the boiler installation.
Disconnect the drain tube from the safety valve.
Release the water from the boiler system using the drain valve.
Remove the safety valve retaining clip.
Heating water temperature sensors
Temperature sensors - If replacement is necessary, remove the sensor together with the retainer and pull out both two connectors.
Emergency thermostat - 100 °C causes the boiler to stop working - error code F20 (unlock manually). The emergency thermostat of the heating circuit is located at the water outlet of the boiler heat exchanger.
To replace it, unscrew the screws located on the thermostat holder, remove the thermostat along with the holder and disconnect both connectors.
Pressure meter
The pressure sensor is used to determine the water pressure in the boiler (heating system). If there is a lack of heating agent in the boiler, the pressure sensor will transmit information to the control board, which will give a command to stop it.
As the water pressure increases, the volume of the membrane carrying the magnet will increase. Opposite the magnet there is a Gall sensor, which changes the incoming voltage on the Proterm Skat boiler control board depending on changes in parameters magnetic field. The change in the magnetic field parameters depends on the change in the distance of the Gall sensor relative to the position of the magnet.
Before removing the pressure sensor, it is necessary to close the heating water supply and then drain the water from the unit using the drain valve. Pull slightly to remove the pressure sensor connector. Using a flathead screwdriver, remove the pressure sensor safety clamp. Remove the pressure sensor by pulling it towards you.
Dismantling the heating water circuit heat exchanger
Heat exchanger dismantling work:
Remove the front cover, side panels and top cover of the boiler unit.
Disconnect the heating element wires from the Skat Protherm electric boiler control board and the terminal box and disconnect the grounding conductor.
Disconnect the heating water supply pipe at the bottom of the heat exchanger.
Remove the heating water drain pipe at the top of the heat exchanger.
Loosen and then remove the bolts located at the top.
Pull up slightly to remove the heat exchanger from the boiler.
Removing the heating coils
Dismantling operations:
Remove the front panel of the boiler and its top or bottom cover (depending on which element needs to be replaced).
Disconnect the appropriate heating element wires from the control board and terminal block, as well as the grounding conductor.
Using a wrench of appropriate size, unscrew the heating element from the heat exchanger body in a counterclockwise direction.
Expansion tank
The expansion tank serves to equalize the pressure of heating water, the volume of which increases when heated. The expansion tank of the Proterm Skat electric boiler is designed for a maximum amount of water in the heating system - 90 liters (at a temperature of 75 °C). The expansion tank is located at the rear of the unit.
Before filling the heating system with water, check the pressure in the expansion tank. The initial pressure in it should be 0.2 bar greater than the static height of the water column in the heating system.
Fill the heating system with water. The filling pressure should be 0.2 - 0.3 bar higher than the water pressure in the expansion tank. The water pressure when filling the system is checked using a pressure gauge on the water supply side, in a cold state and after removing air from the system.
The valve for filling the expansion tank is located in its upper part. If water flows out of the expansion tank fill valve, this means that its membrane is damaged. In this case, the expansion tank must be replaced.
Work on removing the expansion tank:
Loosen and unscrew the screws located on the top of the boiler frame.
Loosen and unscrew the nut of the inlet pipe leading to the expansion tank.
Pull upward to remove the expansion tank.
When reinstalling, new gaskets must be provided.
Skat Protherm electric boilers do not have their own bypass, so it is recommended to install it directly in heating systems.
The boiler connection terminals must not be subject to loads from the heating system pipes. To do this, it is necessary to accurately observe the dimensions of the ends of all connected pipes, both in terms of height and relative to the distances from the wall and the relative position of the individual inputs and outputs in relation to each other.
It is recommended to connect the electric boiler to the heating system in such a way that, if it is necessary to repair the boiler, heating water can only be discharged from it. During reconstruction, unfavorable layout, etc. The boiler can be connected to the heating system using flexible hoses intended exclusively for this purpose.
The flexible hoses used must be as short as possible, protected from mechanical and chemical influences, as well as damage. The flexible hoses used must be replaced before the end of their service life or when they lose their ability to reliably perform their functions.
new.
The Proterm Skat electric boiler can be used to heat water entering the underfloor heating system. In this case, it is necessary to connect an emergency thermostat designed for underfloor heating systems to the boiler (not included in the delivery package).
An emergency thermostat for regulating water temperature in underfloor heating systems is connected to the boiler power supply terminal block. Typically, boiler systems are equipped with a factory-installed jumper that short-circuits the terminals for connecting an emergency thermostat for underfloor heating systems. The jumper must be removed before connecting the thermostat.
The heating system, according to the readings of the boiler devices, must be filled with water at least until it reaches hydraulic pressure at 1 bar (corresponding to the hydrostatic height of a 10-meter water column).
If a room thermostat is installed in a reference room, it is necessary that at least one of the heating batteries located there does not have a thermostatic valve installed.
To increase thermal comfort in the room in which the room thermostat is located, we recommend not installing thermostatic heads on the heating radiators at all.
Before installing a new Skat Protherm boiler, the heating system must be thoroughly cleaned. It is recommended to install a sump tank in front of the boiler, namely on the return heating water pipeline. The septic tank must be constructed in such a way that it can be cleaned regularly without
need to drain large quantity heating water.
A settling tank can be combined with a filter, but a filter and sieve alone is not sufficient protection. Both the filter and the settling tank need to be checked and cleaned regularly.
Installation work for the electric boiler Proterm Skat:
The mechanical structure of the boiler unit with a pump and accessories is hung on the rail.
The covering can be removed and secured to the rear wall with screws.
To install the boiler, it is necessary to choose a place that will allow service operations to be carried out without major obstacles.
If the boiler is installed in an open system, the water level of the heating system must create a pressure of 1 bar.
In heating systems equipped with thermostatic valves, the water circulation can be completely closed, in which case it is necessary to install a bypass pipe that is not equipped with a thermostatic valve or use a bypass.
When installing the front panel, make sure that the plastic frame sits exactly in place and that there is a grounding pad under each screw that secures the front panel.
Electrical connection of the Proterm Skat boiler
Skat Protherm electric boilers are designed for permanent connection to fixed electrical wiring. It is necessary to install a disconnecting device in it - a main switch, the distance between the open contacts of which is at least 3 mm for all poles, provided that the commissioning instructions are followed.
Before installing the boiler, the user is required to ensure the installation of separate power wiring, including the main switch of the heating system, fuses, and also carry out other necessary changes in the internal electrical wiring.
In cases where it is not possible to connect to a three-phase electrical network, Proterm Skat boilers of the 6 and 9 kW power series can be connected to a single-phase one. To do this, you need to use the connecting bridge included in the boiler delivery package.
Using a connecting bridge, the contacts of the phase wires are mutually connected on the terminal block, designed to supply power voltage to the unit.
Elements of the Skat Protherm boiler control board:
Connecting heating elements
- K8 connector
- connector 1 (pressure sensor, extract air temperature sensor)
- connector K5 (control panel)
- connector J3 (HDO)

__________________________________________________________________________Protherm products are popular in the global heating equipment market due to their reliability and high quality. Its equipment is supplied to many countries for corporate and private clients. The consumer can easily select heating equipment, because the lineup reaches almost 100 positions, including:
- electric, gas, diesel boilers of various modifications;
- storage and instantaneous water heaters;
- various sensors and automation for heating units.
In the line of heating equipment of the PROTHERM brand, the line of electric boilers for heating is represented by the Skat series. The company has created a wide network service centers, which ensure uninterrupted operation of the company’s heating equipment adapted to Russian conditions. Therefore, it is profitable to buy an electric boiler Proterm Skat due to the availability of a network service. The company's official website contains a catalog of Protherm products for 2016. It contains the most up-to-date information about heating units produced by the company.
In the company’s catalog for 2016, the Protherm Skat wall-mounted electric boiler is presented in 8 models with capacities from 6 kW to 28 kW. Equipment with the letter “K” is connected to a 220/380 V network. All models of this line of electric boilers are double-circuit. The company also produces a line of models of single-circuit boilers; their name contains the abbreviation “KR 13”. Single-circuit boilers are produced in the same power range as double-circuit boilers. The dimensions and weight of all models are the same and their main difference is the power, depending on the set of installed heating elements and the supply voltage (220/380 V).
The catalog provides the main parameters for the base model Protherm electric heating boiler:
Advantages of Protherm electric boilers
Unlike gas, solid fuel and diesel boilers, heating boilers do not emit any harmful products during their operation; they do not require a chimney or various additional devices.
According to its properties, the Protherm electric boiler is absolutely harmless to the environment, and does not require constant monitoring during operation.
Thus, the Protherm Skat 9k electric boiler, like other models in the company’s line of electric boilers, is fully automated; an LCD display is installed on the front surface of the body, which reflects the set readings. The package includes detailed instructions to the electric boiler Proterm Skat 9, where all actions are indicated to achieve coordinated operation of the unit.
The owner just needs to set desired temperature, and in the future it will be supported by automation, with high accuracy up to one degree. After reaching comfortable temperature the thermostat will send a signal to the boiler control unit, which will turn off the power supply. Electric boilers are safe, because the automation monitors not only the temperature of the coolant, but also its pressure. To prevent sudden voltage surges, the boiler output to maximum mode carried out in stages. A double-circuit electric boiler Skat of any model, in addition to heating, heats water for the hot water supply system (DHW).
Electrical heating boilers extremely compact and fits perfectly into any interior. Wall-mounted electric boilers Proterm Skat can heat areas from 60 to 280 m2 and are perfect for heating apartments, country houses, cottages and offices. There are especially good reviews for the Proterm Skat 6 kW electric boiler, which can provide a small office with heat and hot water. There is an example when the owner installed a remote tank, the water in which is heated at night, since the night tariff is valid in the region, and during the day it releases heat into the room.
Installation and connection of electric boilers
The installation and installation instructions for the unit included in the delivery package for Protherm electric boilers contain a warning that in the event of mechanical damage to the casing or damage to the integrity of the components and blocks of the boiler, the warranty becomes invalid. Therefore, when installing yourself, you need to work carefully and strictly follow the recommendations. In order for the Proterm wall-mounted double-circuit electric boiler to function correctly, it must be connected in accordance with the requirements of the instructions.
Connection to the electrical network of the Proterm 6 kW boiler
The boiler with a nominal power of 6 kW is available in two options for connecting heating elements for 220 V and 380 V. Boilers and heating elements are no different, and the 380 V boiler version can easily be converted into a 220 V version. To do this, it is enough to change the switching scheme. If the boiler is connected to a three-phase network, then 2 kW heating elements in each phase consume a current of about 10 A, since the line voltage is 220 V. Therefore, wiring of 1.5 square meters and a three-phase 10 A circuit breaker will ensure normal operation.
With a single-phase network, everything is somewhat more complicated. The boiler has 6 heating elements installed and with a maximum power of 6 kW, the current consumption will be slightly more than 27 A, therefore, you will already need a wire with a cross-section of at least 6 squares and a 30 A circuit breaker. All of the above applies to any electric heating boiler for the home, of any power , only the current consumption values and the required wire cross-section will depend on the power.
According to the tables for choosing a section copper wire a current of 1 A requires a cross section of 0.17 mm2. The current in the circuit is determined by well-known formula– I = P/U, in which:
The first thing you need to pay attention to Special attention- This correct selection sections electric cable nutrition. After all, for example, an electric boiler Proterm Skat 24 with a rated power of 24 kW, when connected to a three-phase network, will consume a current of about 30 A for each phase. It is not advisable to connect such a powerful boiler to a single-phase network, because in this case the current at maximum power will increase to 100 A. An electric boiler must be connected only through an RCD.
As for the installation location, the requirements for installing electric boilers are not as stringent as for gas or solid fuel units. And the price of an electric boiler for heating a home is much lower than the prices of other types of boilers.
You can install an electric boiler anywhere, but this place should provide easy access for adjusting the unit or quickly shutting it down if necessary.
If the circuit diagram contains several electric boilers, they are connected in parallel. According to electrical safety regulations, an electric heating device must be grounded.
How to choose an electric boiler for heating your home
All are compact, easy to use and safe. They do not need chimneys or special premises for installation, and the efficiency is close to 100%. These properties make them superior to other types of boilers. To heat a specific room, an electric boiler is selected primarily based on power. It is believed that one kilowatt is sufficient to heat 10 m2. Consequently, the electric boiler Proterm Skat 12 with a rated power of 12 kW can provide heat to rooms with a total area of 120 m2.
High quality and reliability are confirmed by reviews found on the Internet for the electric boiler Proterm Skat 12, in which they write that the boiler is silent, simply and easily adjusted and does not require constant attention (“installed, turned on and forgotten”).
Popular electric boilers from Protherm
For connection as a backup to an existing heating system or for heating small house with an area of up to 90 m2, the wall-mounted electric boiler Protherm Skat 9 kr 13 with the ability to use a 220/380 V network is in greatest demand. The boiler is single-circuit with electronic control and with a built-in circulation pump and. Its main characteristics fully correspond to the base model.
If there is a need to organize hot water supply, the manufacturer has provided the possibility of connecting an external tank. When sold, the connection pipes are closed with plugs. The difference in price between single-circuit and double-circuit boilers small. For example, the price of a Proterm Skat 9 kW wall-mounted double-circuit boiler is comparable to the price of a boiler of similar power, but single-circuit. In different stores selling heating equipment, the price of the Proterm Skat 9 electric boiler ranges from 490 to 560 USD.
According to its technical characteristics, requirements for installation, adjustment and design electric boilers significantly preferable to gas and . Their installation does not require a separate room, and the electric boiler itself can be installed anywhere in the heating circuit, as long as it has easy access. Electronics developed by Protherm independently monitors the level of air temperature in the room and creates comfort and coziness in the home. The only obstacle that limits the use of electric boilers is the high price of electricity, which tends to increase.
