Many faults gas boiler can be fixed with your own hands, without resorting to the expensive services of a gas service or equally expensive private maintenance and adjustment specialists gas equipment.
The only rule, which we will immediately mention, is that you need to understand what you are doing and for what purpose.
Seasonal service
Seasonal maintenance of a gas boiler consists of cleaning it from contaminants and checking its performance. To access the boiler elements, it is necessary to dismantle the casing or casing. To do this, we decide on the method of fastening it, different models boilers this can be done in different ways. Most often these are several self-tapping screws and several latches in the upper part of the casing.
Having gained access to the internal parts of the boiler, we do not remove anything else when performing seasonal maintenance. Using a soft metal brush, a toothbrush and fine-grained sandpaper, we begin to remove carbon deposits from all parts of the boiler:
- heat exchanger;
- burners;
- igniter, if available.
We use the above-mentioned tool wherever it is convenient, without putting too much pressure on the metal brush. Next, use a compressor to blow out the accumulated dust. You can use a rubber tube or a straw from medical dropper, simply blowing into it and directing its other end into the boiler.
Important! Any work on the boiler is carried out with the gas valve closed.
Using a thin awl or a strong needle, you need to clean all the holes on the burner and igniter, and then, after cleaning them again, for example, with a toothbrush, blow them out again. If there are overhead sensors, the places where they contact the parts of the boiler need to be lightly cleaned sandpaper, and then wipe with a soft woolen cloth.
The ignition and flame control electrodes can be cleaned well only with a woolen cloth, without the use of cleaning agents. If there are submersible temperature sensors, it is necessary to remove them from the sleeves, remove any liquid from the sleeve, and thoroughly clean the inside of the sleeve using a metal brush small size or a loose length of steel cable of suitable size. After rough cleaning, clean the sleeve with a cloth wrapped around a screwdriver, then fill the sleeve two-thirds with machine oil and install the sensor.
After completing this work, the boiler is thoroughly vacuumed. In accessible places, clean dust and dirt with a damp cloth. We put the casing in place. We check the presence of draft in the chimney by attaching a sheet the size of a notebook to the chimney opening, or by blowing a stream of smoke into the ignition hole of the igniter, gas tap on the descent to the boiler must be closed.
We check places of seals and possible gas leaks using the soaping method. If there is normal draft, a test run of the boiler is performed, which must be filled with coolant. In parallel with the work on cleaning the boiler, it is visually inspected for mechanical damage and coolant leaks. At this point, seasonal maintenance can be considered complete.
Cleaning the heat exchanger
Produced with a solution of hydrochloric acid purchased from trading network and designed specifically for this purpose. Cleaning is carried out for the main heat exchangers of wall-mounted gas boilers and heat exchangers for hot water preparation. The cross-section of the channels of such heat exchangers is small, which is why they are susceptible to contamination by salt deposits.
As a rule, the water jacket of floor-standing gas boilers is not cleaned. To perform cleaning, the heat exchanger must be removed. To do this, remove the boiler casing, unscrew the supply pipes to the heat exchanger, after draining the water from the boiler.
We remove the heat exchanger from the boiler. Wear rubber gloves and use plastic container for collecting spent acid. The method is not complicated. Carefully pour the acid solution into the heat exchanger until it is completely filled. If the heat exchanger is clogged with scale, active foam will be released. Leave the heat exchanger for 10–15 minutes.
We drain the spent acid into a container and refill the heat exchanger with a new portion. We wait the same ten minutes. Drain the solution and rinse the heat exchanger with running water. We put a piece of hose on the nearest water tap and spill water on the heat exchanger. Let's fill the heat exchanger again with an acid solution. If there is no active release of foam, and when the heat exchanger is spilled with water, no significant resistance to flow is visible, it means that the heat exchanger has been washed and can be reinstalled in the reverse order.
Cleaning the burner from carbon deposits
The method for cleaning the burner from carbon deposits has already been described above. However, heavy carbon deposits cannot always be dealt with using only mechanical cleaning. For such cases, special chemicals. It makes no sense to recommend anything; all the remedies are quite effective. The cleaning method boils down to applying the product in the form of a solution to the surface to be cleaned, leaving it for a certain time and then removing the exfoliated carbon deposits, more often mechanically. You should familiarize yourself in more detail with the cleaning method with one or another product when purchasing it.
In particularly severe cases, for example, when coolant gets on the burner, it must be completely removed from the boiler and immersed in a cleaning solution for several hours. Then remove the burner and ignite it in the flame of a portable gas burner. After applying the solution again, use a metal brush or brush to remove any remaining carbon deposits.
Checking the smoke exhaust duct
The smoke exhaust duct is checked using a mirror. We insert the mirror into the channel at a slight angle. In the mirror we should see the light at the end of the chimney. When performing this operation, it is convenient to use a so-called selfie stick with a mirror attached to it.
Eliminating water leaks at pipeline connections
To eliminate the leak, you need to unpack the connection, clean the threads of old tow and paint. Then, using FUM tape, sealing thread or thread locker, pack the connection again. Check the quality of work by filling the pipeline and boiler with water.
Checking and eliminating gas leaks
All accessible gas leak points must be washed with a soap solution or special means to check for gas leaks. The solution for washing is prepared from laundry soap, planing it into a container with warm water and stirring until a thick foam is obtained. If there is a gas leak, a soap bubble will blow out on the foam. You can fix a leak in the same way as water leaking through threaded connections.
Burner replacement
Replacing a gas boiler burner will require more attention and care. You should purchase a new burner of the exact same model as the one installed on your boiler. Never install a burner that is not designed for your boiler model.
The beginning is the same - remove the boiler casing. Having gained access to the burner, we carefully inspect the tubes and sensors connected to the burner. Their location should be remembered so that when assembling a new burner you do not confuse which one is connected where.
How to remove gas burner. 1. Fastening the burner to the combustion chamber body. 2. Wires of the electrode igniter and flame sensor. 3. Gas-air mixture supply pipe
Due to the wide variety of boiler models, it is impossible to give specific recommendations, but in any case the following will be present:
- gas supply tube to the burner;
- gas pressure sensor to the burner;
- gas valve.
There may be a control tube from the draft sensor or an electrical connection (wires) from the same draft sensor or temperature sensor. If you use a burner of the same model as yours, remembering and connecting all the wires and tubes will not be difficult.
Replacing a hand burner installed in a wood stove is even easier to cope with. We unscrew the screws that secure it to the plate and two tubes: gas supply and gas supply to the igniter. We take out the old burner, insert a new one, screw on the tubes, and tighten the burner mounting bolts.
It is not worthwhile to repair the primitive automation of such a burner; the result may lead to unsafe operation of the boiler. The most difficult task is replacing the burner of a wall-mounted gas boiler, which is stuffed with electronics and a large number of sensors. But there is no need to panic here either, the principle is the same: it is good to remember the location of all connections to the burner.
Trying to increase their importance, gas specialists say that such a burner should be “tied” to the boiler by flashing the electronic unit or adjusting the boiler. The burner is just iron and cannot be adjusted in any way. The combustion itself may require adjustments, but this is no longer related to replacing the burner itself. If the burner is made for the boiler model on which it is installed, then the combustion will be correct, however, provided that no attempt was made to regulate it on the old burner.
Replacing the temperature sensor
The need to replace the temperature sensor arises when, when setting a specific temperature regime operation, the boiler either does not comply with it, or, even worse, goes into boiling mode, which can lead to rupture of the water jacket of the boiler or its heat exchanger.
Temperature sensors according to the installation method in the boiler can be overhead and submersible. Clip-on sensors are installed on boiler pipes on clips that press the sensor to this pipe. Replacing them is quite simple. Disconnect the old one and install the new one. We put the chip (electrical contact) in place of the old one.
Immersion sensors can be of two types: direct immersion and located in a sleeve filled with oil. When replacing the first ones, it is necessary to drain the water from the boiler and unscrew the sensor. Pay attention to how the threads were sealed at the sensor mounting location. This could be as simple as tapered threads, using thread locker (glue), gaskets, or O-rings. Sealing with flax and other materials is not used. Using the same sealing method, install the new sensor.
When replacing sensors installed in sleeves, there is no need to drain water from the boiler. After releasing the fixing nut, pull out the sensor, check for oil in the sleeve, install a new sensor, securing it with the nut. Most simple option Such a sensor is an alcohol thermometer installed in a sleeve for visual monitoring of the temperature in the boiler.
Questions regarding the operation of Immergaz boilers
Question: A gas boiler Immergaz eolo star 24 3 e was installed, it showed error 11, what should I do?
Answer: If the pressure in the system has dropped below 0.8 kg, you need to increase the pressure with make-up to 1.2 kg and reset the “RESET” error, then the boiler should start. Possibly insufficient smoke exhaust flow. Check the smoke sensor and fan. There may be dirt in the pipe.
Question: We connected the wall-mounted boiler EOLO MYTHOS 24 2E IMMERGAS, installed it myself, connected everything according to the instructions: voltage stabilizer, brown wire per phase, grounding everything as it should be! During the initial startup, the boiler started up, but a day later it gave me error 01 (ignition block), I reset the error with the "RESET" button, and this repeats several times a day. I don't know what the problem is, can someone help?
suggest.
Answer: Error 01 - no gas. When it lights up, you need to check for gas in the stove. If it is not there, then contact Gorgaz. If there is, then to the service.
Question: when the Imergaz boiler is turned on, error 10 appears, what should I do?
Answer: The pressure in the heating system has dropped. You need to fill it out.
Question: I have an Imergaz EOLO Star 24 gas boiler installed and connected. Lately, error 11 keeps popping up. I cleaned everything, coaxial pipe, fan, chimney, etc. But the error still does not go away. On the street strong wind The house immediately gets cold.
When you turn on the hot water, after a few seconds the boiler begins to crackle and the water temperature quickly begins to rise on the indicator. If you turn off the hot water supply, then the water supply is very short. I would say that the boiler does not get the required amount of cold water into the tank and begins to heat itself. What to do in this case?
Answer: Clean the DHW filter (flask).
Question: The situation is the following, we bought a house, 130 square meters, a wall-mounted immergas boiler is installed. At the beginning of the repair work everything was fine, I worked and worked. Once I entered the house, I discovered that the batteries were not hot, just warm, I looked at the boiler, but the red light was constantly on, I finally got through to the technician, he told me to do a reset (RESET), I did it, the boiler started working, the next day the situation
repeated! But in our city, no one has ever encountered such boilers, and everyone advises changing it! I don’t know what to do, everything is too expensive to repair.
Answer: This occurs due to freezing of the exhaust pipe to remove burnt gases. If you look at the boiler from above, there are hatches near the exhaust pipe exit from the boiler on the left and right; open one of them and the problem is solved.
Question: We open the feed to the gas boiler Immergaz EOLO STAR 24 3e and nothing can be heard as it works, and the pressure is at 0.8! What to do?
Answer: The only problem is the pressure in DHW system, it is less than in the heating system. You need to increase the pressure using a pump or buy a pump for the hot water system.
Question: We installed and connected the Immergaz Nike star 23 kw wall-mounted boiler, which has been in operation for about 4 years. This is our second year. It will be the third winter and it seems that the overall temperature is lower. It should be warmer. When igniting, it starts clicking - about 5-6 seconds. Then it works for 40 seconds or up to a minute and goes out. What could it be?
Answer: Check the return filter, if installed.
Question: The house has a gas boiler Immergas Eolo Star 24 sq. house 160 sq. What is better: a temperature sensor or a boiler for the temperature of the heating circuit?
Answer: Install a room thermostat.
Question: Please advise, I want to install an immergas victrics 26 2i boiler, house 100 m2, panel vulture, bottled gas, they say it is an economical boiler, because... the lower limit of operation is 5 kW, I understand that I will have to install large radiators because I don’t have a heated floor, I want to use it in 40/50 mode. It’s clear that it’s a bit expensive, I’m willing to spend money, is it a good model and is it worth installing?
Answer: A condensing boiler is beneficial when low temperature mode. You will really have to double the power of the radiators (approximately), spending about 60-70% on this Money, additionally. A condensing boiler saves approximately 25-30% of gas.
But will you be able to recoup it in the end:
The cost of boilers is two times different.
- costs of organizing low-temperature conditions.
- more expensive spare parts (differ by 2-3 times, some by 4 times).
- more expensive service maintenance annual.
Boiler Victrix 26 2i - can modulate up to 3 kW.
Question: Tell me what is better to switch the boiler to a lower power or install an external temperature sensor, otherwise it often turns on and works for a couple of minutes.
Answer: You have a small room area: Be sure to buy a room thermostat. When installing it, it is recommended to set the heating temperature to 70 degrees on the boiler.
Question: We connected the Imergaz Eolo Star 24 boiler, but the water pressure drops and displays error 10. When I add pressure, the boiler starts and runs after a while and turns off again. Is it that the expansion tank is capped?
Answer: No, not expansion tank. There may be problems in the heating system or in the boiler (heat exchanger), etc.
Question: When the DHW is turned on, either hot or cold water flows. Code E-27 is displayed, but the DHW pressure is good, what could it be?
Answer: Setting up the boiler, if it started immediately after the first start-up. So whatever - the gas block does not modulate or is clogged with shavings in the pipe, flow switch, etc.
Question: Tell me, have you installed an immergas boiler, it heats the water great, but the heating doesn’t heat at all?
Answer: 1. Please turn on the winter mode (snowman). Then the boiler will start working in heating mode.
2. Look at the set temperature of the coolant (water) in the heating system (buttons with a picture - radiator). Maybe there is simply no need to work in heating mode - summer, warm.
3. If you use room thermostat, then look at what temperature is set on it. Maybe there is simply no need to work in heating mode - summer, warm.
4. If the boiler is not working properly, it should go into emergency mode and indicate an error code on the display. Follow the instructions in the user manual or call customer service.
Question: Yesterday we got connected to the Immergas Eolo Star boiler. During the briefing, they explained that during summer operation of the boiler, you can use either warm or cold water. Those. cannot be mixed. Explain why?
Answer: You can install any comfortable temperature preparing hot water. And in any mode (winter, summer). They simply recommend setting a comfortable hot water temperature, so that the cooked hot water, mix with cold as little as possible. This is to save gas. For example, a comfortable water temperature is 42-43 C, then set it to 45-46 C, not 55 C.
Question: We have an Immergas gas boiler connected. Can you tell me what is the correct temperature to set in summer?
Answer: DHW temperature. - Turn it on in the summer summer mode(umbrella) and set yourself a comfortable temperature of hot water, as in other things in winter. Heating temperature - If it suddenly becomes cold and there is a need for heating, then turn on the winter mode (snowman). And also set any coolant temperature. The best thing, of course, use a room thermostat.
Question: I have an Imergaz eolo star 24 3e boiler installed, the problem is that when I turn on the hot water, the boiler makes a wheezing sound and wheezes until I turn off the water, what could this be?
Answer: The boiler needs to be serviced: the heat exchanger is clogged and needs to be flushed. Clean the fan when turning on the boiler DHW mode, the boiler reaches maximum operation, and the fan cannot cope due to dust (dirt), noise and vibration begin.
Question: I have an IMMERGAS NIKE STAR gas boiler. Eight months in use. Summer mode is now enabled. There is no hot water. Displays error code 10. Water pressure is normal. But if you switch to winter mode, hot water appears. How to find out the reason?
Answer: Error 10 - no pressure in the heating system. Options: problem with the heat exchanger, the make-up valve does not hold.
Question: I installed a new Immergas turbocharged boiler, 01 is flashing. I rebooted - it doesn’t help, I called a specialist and replaced it with another new board, it still gives the 01 signal. What should I do?
Answer: 1. Check whether there is gas at all in the house. Turn on gas stove, if there is no gas there, then call the gas utility. If there is gas in the stove, then open the gas tap, sometimes people forget to open it.
Call a specialist:
Check the gas valve setting to minimum.
- check the gas valve for modulation (drive it)
- it happens that the valve sticks (knock on it, and it will start working without problems), this can only happen when the boiler is put into operation for the first time. if problems are visible, replace it.
Check the grounding, there are cases under certain conditions when the flame ionization sensor does not work and displays error 01.
Question: It’s been six months since the Immergaz Eolo mini boiler was connected. The problem is that the ignition periodically did not work, mainly for hot water, and at first fault code 04 was displayed. After the preventive maintenance, it worked perfectly for half a day, after which the ignition disappeared altogether, neither the hot water nor the heating works, the display does not show a fault code. What is the reason?
Answer: The problem is in the control board, or in the ignition electrode (which happens very rarely).
Question: Tell me, who knows whether this problem can be eliminated at all. I have an Immergas boiler connected, almost new, only 1 year old. There is no hot water supply in the system constant temperature, what temperature do not set it is unpleasant to wash, the water flows either hot or cold, what can be done? And so everything works properly, no errors are displayed.
Answer: It shouldn't be that way. The boiler has a modulation function, and the boiler must instantly respond to the water flow and its temperature. It must also clearly maintain the set temperature. This may be due to incorrect settings of the boiler or it was not set up at all. It is necessary to know whether this was from the very beginning (the first launch) or happened during the process.
Question: my Imergas boiler EOLO STAR 24 3 E has been running for three years, now sometimes this problem occurs when turning on the hot water, the pressure in the heating system drops and error 10 blinks. What can I see?
Answer: Close the heating system feed tap tightly. Call the service, you need to replace the heat exchanger (this can only happen during annual flushing of the heat exchanger).
Question: Boiler Immergas Eolo Star 23KW. The boiler is about 6 years old, recently the pressure has dropped to 0, often after using hot water for 10 minutes or more. It drops to zero several times a day. I checked the RB, it turned out the pressure was 0. I bought a pump with a pressure gauge and pumped it up to 1 bar. I filled the system to 1.2 bar, in the morning error 10, pressure 0. Day 3 I’m experimenting, looking for the problem.
The make-up valve is turned on and does not flow, I checked the discharge valve, screwed on the Mayevsky valve to check. I shut off the heating and hot water circuit from the boiler at night to understand where the leak was - in the system or in the boiler itself - overnight the pressure dropped from 1.2 to 0.5, error 10. This means the problem is in the boiler itself. I checked the pressure in the RB again, 1 bar. For the experiment I added up to 1.7.
It didn't help, it crashes. A day later, that is, today, I drained all the air from the RB and pumped it back up to 1 bar. On this moment, after 4 hours of observation, the pressure remains 1.8 on the pressure gauge at the moment. I hope everything is back to normal. The question is, and yet, if the pressure drops again, where to look next, considering that I have already checked everywhere. The last thought is that the problem may be a breakdown of the heat exchanger wall, when water from the heating circuit leaks into the DHW circuit and, accordingly, the pressure drops when using DHW. What are your thoughts?
Answer: Clean the filter on the heating system. If cleaning the filter does not help, call service and repair the pump.
Question: I have an immergas boiler connected, the display is flashing 10 pressure 0.5, I checked there are no leaks anywhere. I turn the pressure regulator or nothing. the pressure does not rise. What to do?
Answer: This means low pressure in the cold water supply, and the heating system cannot be pumped up. Reduce the pressure in the heating system and try to increase it back to 0.5 atm. If it works, then you need to pump up the heating system using a pump. The pressure gauge may be broken, but if you drain water from the heating system, it will show the same pressure. Replacement.
Question: when you turn on the hot water, the Immergas Eolo mini boiler begins to vibrate, the higher the temperature, the greater the vibration, and when you turn on the water and heating at the same time, nothing works at all! what could it be?
Answer: Please do annual maintenance. Fan cleaning. If that doesn't help, then you need to look at the balancing rings. Or replacing the entire fan. It is impossible to turn on heating and hot water at the same time in boilers (of any manufacturer). Priority is always hot water.

Has the Immergas boiler failed? Operation is blocked and errors are shown on the display? Don't worry, this is how the security system reports a problem. What to do? Look at the instructions and find out the code designation. If the instructions are lost or you do not understand the technical language, then refer to our publication. We have clearly described the errors of Immergaz boilers.
Operation and installation of Immergas boilers
Italian manufacturer heating technology Immergaz is aimed at all segments of the population. From a wide range you can choose Economy Class models or high-tech devices at a high price.
The equipment is adapted for operation with unstable pressure in the gas main - up to 3 mbar. The design is equipped with the following components and parts:
- Gas burner with electric ignition;
- Circulation pump from Grandfos. The equipment has proven itself to be reliable and quiet;
- A bypass with a regulation system protects the heat exchanger from overheating;
- The reed sensor measures the temperature of the coolant flow;
- Antifreeze mode. If the temperature drops to 4 degrees, the boiler starts automatically. After which constant heating is maintained at 40 degrees;
- External thermostat available. It can be connected as desired.
The range includes conventional convection models, as well as condensing ones. The latter are characterized by increased efficiency of more than 100%. By design, there are single-circuit and double-circuit units. Combustion chambers - open and closed type.
Anti-scale protection is provided. The pump does not stop when heating is complete. He pumps for about 3 more minutes cold water throughout the system, relieving the heat load.
Errors and malfunctions
Equipment is not insured against breakdowns. If you see an error code, you can find its meaning and solutions in the table presented. First of all, it is recommended to restart the boiler to avoid a system failure. If the symbols appear again, proceed with the repair.

Problems with Immergaz with automatic unlocking
Once you eliminate the cause of the malfunction, the board will automatically resume operation and heating.
What codes are found:
- b 18 - violation of heating of the supply circuit (over 95 ° C). Eliminate the causes of poor coolant circulation (clogged filters, heat exchanger, pump blockage);
- b 19 - the return heating level has exceeded 90°C. See solution for b 18;
- b 24/b 30 - supply and return thermistors give different readings. The difference is 10°C. Diagnostics of the heat exchanger. Descaling;
- b 25 - rapid increase in degree on the supply line. Feed the circuit with water;
- b 26 - pressure decreased. Measure readings, add coolant to the circuit, configure the pump;
- b 28/b 29 - the fan does not function. Replace the unit if it breaks;
- b 33/b 38 - short circuit, break in the DHW thermistor. Connect the new part;
- b 65 - the fan does not start for a long time. Diagnostics and replacement.
Another common fault is a yellow, uneven flame. In this case, the burner should be cleaned of soot and dust. Also remove dirt from the chimney shaft - it disrupts draft.
Not all models are equipped with a display. Some issue a failure code by glowing indicators. For example, Immergas Nike Star/Mini.
If you cannot fix the problem yourself and the symbols appear on the screen again, it is better to call a technician.
Nowadays, autonomous heat supply systems have become very popular. The main component of such a system is the heat source. Most often this is a gas boiler. Such equipment has good quality and decent characteristics.
Modern boilers have their own protection system:
- Lack of traction;
- Burner goes out;
- Heat exchanger overheating.
If malfunctions occur, you can use the equipment only after they have been eliminated.
In some cases, repairs can be done yourself. But in order to prevent breakdowns from occurring, you need to observe and carry out:
- Operating rules;
- Preventive actions.
Compliance with these measures will allow you to operate the equipment for a long time without breakdowns.
Having heating system and hot water supply, you can fully experience the benefits self-adjustment temperature conditions. But in order for operation to be completely safe and the services received to be of high quality, it is necessary to periodically repair the heating boiler.
What you need to know about the system design
Any heat generator can break down, this can happen for several reasons, for example:
- Damage to the expansion tank;
- The instructions and operating rules have been violated;
- Poor quality elements or components.
Whatever the malfunction, repairs must be carried out carefully and in accordance with established standards.
When repairing, you need to pay Special attention on the serviceability of the sensors. For example, if a carbon monoxide sensor fails, there will be a high probability of inhaling dangerous gases.
Any master or person who decides to carry out repairs on their own should know what safety groups there are and what they consist of:
- Traction sensors along with plates. They are rated at seventy-five degrees. This device helps to monitor the state of drafts in the chimney or their exit into smoke eliminators. In the latter, the sensor heats up and triggers. It is best if a gas alarm is purchased in conjunction with this sensor;
- A monostat is installed to protect turbo boilers from poor removal flue gases. May be due to a contaminated heat exchanger or chimney;
- Limit thermostat. It controls the water in the boiler. If it boils, the overheating sensor turns off the boiler;
- Ionization electrode. Installed to monitor the presence of flame. Often, repairing a heating boiler begins with checking the electrodes, because operating gas boilers without a flame can lead to an explosion;
- Burst valve. Serves to monitor pressure. At a pressure above 3 bar, the boiler discharges dangerous excess.
Fulfill renovation work Control boards can only be installed by specialists. Because they have the experience and the necessary equipment.
Important! In most cases, the control panel fails due to power surges electric current, so you need to take care of installing a voltage stabilizer.
The repair work itself for such boards is in most cases the same for all brands of manufacturers, but there may be slight differences. Therefore, there is no need to get into the “brains” of your boiler, as you can cause trouble.
Repair Notes
Never immediately supply full voltage to the equipment, because repairs of heating boilers may stop there due to failure of the automation and wiring.
For installation, you need to use only sensors that are correct for the job, as recommended by the manufacturer. Use stabilizers to avoid damaging wiring and sensors. Most manufacturers' instructions indicate all sorts of problems with the operation of the boiler and what errors it may show. Carefully studying the instructions is already half the battle!
Self-repair – important point, on the quality of which your life will depend. People have been studying this work for many years.
Do I need to do the repairs myself?
All heating boilers- This complex systems. Their main danger is the use of explosive fuel. To control the operation of the heat source, automation is used. In addition to maintaining optimal operation, it also signals problems with the equipment.
We agree with the opinion of experts and argue that boiler repairs should only be carried out by professionals, but in some cases (replacing a small unit) you can limit yourself to repairs yourself.
Let's look at the most common problem with flame loss. The reason for this may be:
- Damper clogged;
- Emergency valve activation.
To deal with the first reason, you need to make sure that the room does not smell of gas and check the chimney draft. In the event that flue gases enter the premises, it is prohibited to operate the equipment. You need to urgently contact a repair shop.
If the equipment overheats, then it is quite possible that the heat exchanger is dirty (you can find its photos and videos in our gallery) or the automation has failed. You need to ventilate the room well and seek help from specialists.
Important! If you smell gas in the room, turn off the boiler, turn off the gas and leave the room. In this case, repairs can only be performed by professionals.
Your actions:
- We wait until the boiler cools down and check the draft and the smell of gas;
- If there is draft and there is no smell of gas, we try to start the boiler;
- If the startup fails, then it is quite possible that the combustion sensor has broken down. There may also be contamination in the pipe through which the gas flows.
Bottom line
It is better not to repair the boiler yourself, because this can lead to serious consequences. It is best to have periodic inspections performed by professionals; the cost of these services is negligible.
