Purmo compact c22 technical data. Purmo radiators: technical characteristics of Finnish devices. Purmo tubular radiators

Without high-quality radiators it is impossible to create an effective heating system. The rapid and uniform heating of the room depends on this element. Finnish Purmo radiators have all the technical characteristics necessary to create a comfortable microclimate in the house.

Model range of Purmo radiators

Purmo products allow you to install a heating system of any configuration. The company produces both tubular and panel radiators. In addition, the range includes heated towel rails, pipes, convectors and ventilation systems.

Purmo Compact

This is a basic model of a panel-type radiator with a profiled surface, having 4 side holes with ½-inch threads for supplying heating pipes. Products of this model are marked as follows - 11, 12, 22, 33. The first marking value indicates the number of panels along which the coolant moves, the second - the number of rows of internal U-shaped ribs to improve the convection effect. Accordingly, the larger the designation, the more powerful the device will be, but in this case its depth also increases.

Purmo Compact batteries are designed for use in one- and two-pipe heating systems closed type. Depending on the model, the length of the radiator can be from 40 cm to 3 m, and the height - from 30 cm to 90 cm. The permissible pressure is 10 atm. The maximum coolant temperature is +110°C.

If it is necessary to supply pipes from below, a model with bottom connection Ventil Compact, in which the inlets can be located on the left or right side of the radiators. When ordering by phone, this point must be clarified. The Ventil Compact M model has a bottom connection in the middle of the device.

All models with bottom connection are equipped with a thermostatic valve. Its configuration is carried out in production. Additional adjustment is required in rare cases, if for some reason its operation is not satisfactory.

Purmo Plan Compact

The technical characteristics of this radiator are practically no different from the base model. The only difference is a smooth plate superimposed on a profiled panel and a higher cost.

It should be noted that in all models with bottom pipe supply, the coolant supply hole is on the left, and the coolant outlet hole is on the right.

Purmo Ramo Compact

In this model, as in the previous one, the profiled panel is covered with a plate, but it is not smooth, but made in the form of wide horizontal stripes. This decision emphasizes strict design radiator and looks stylish in the interior of the room. The model has the possibility of side and bottom connections. Devices with bottom pipe supply are designated by the word Ventil. This model range includes the following types of radiators - 11, 21, 22, 33, 44. Devices are produced with lengths from 40 cm to 3 m, and heights from 20 cm to 50 cm. Allowable pressure up to 10 atm.

Purmo Hygiene

Special hygienic type of radiators without internal fins. When convection currents move, dust particles rise along with them, which then settle on the inner surface of the radiator. The absence of ribs makes the device easier to clean. The Hygiene model is recommended for installation in rooms where people with allergic diseases live, as well as in hospitals, kindergartens and other public places. In such radiators, the proportion of heat transferred infrared radiation, significantly exceeds convection heat transfer.

The Hygiene model range includes 3 types of batteries - 10, 20, 30. All of them have modifications with Ventil bottom side connection and Ventil M center connection, as well as Plan Hygiene with a smooth overlay plate with all pipe supply options.

Purmo Vertical

Vertical radiators are designed for rooms with limited horizontal space, but which require a large thermal power. The device has 4 holes for side pipe supply and 2 in the bottom center for bottom connection. Vertical radiators are available in the following types - 10, 20, 21, 22, widths from 30 cm to 75 cm and heights from 1.5 m to 2.3 m. Allowable pressure up to 6 atm., maximum coolant temperature - +99°C .

This type of radiator is classified as a designer type and is more suitable for country houses or apartments with an autonomous heating system.

Purmo Air

Metal-plastic windows have good energy efficiency, but they must be opened periodically to ventilate the room, otherwise there is a disadvantage fresh air may cause you to feel unwell. The company's specialists took this problem into account and developed the Air model, which allows you to ventilate the room without opening a window.

The radiator is mounted on an external wall, a through hole is made nearby and a filter is installed. Having passed through it, the cold air is heated by the radiator and dispersed throughout the room. This creates a miniature heated ventilation system. Ventilation equipment is supplied complete with the radiator.

The line of Air models consists of devices of type - 11, 22, 33, length from 70 cm to 3 m and width from 30 cm to 75 cm. Allowable pressure - up to 6 atm., permissible temperature coolant - +110°C.

Delta Laserline

This model belongs to the tubular type of radiators, consisting of sections. The design of each section consists of two heads connected to each other steel pipes. Depending on the model, the number of rows of pipes may be different. By welding, the sections are connected into a single radiator. In this design, the quality of the welds plays an important role. For the manufacture of tubular radiators, laser welding controlled by a computer system is used.

Delta Laserline models have the traditional shape used in these types of batteries, but in a slightly different design. The pipes are not made round, but in the shape of the letter D, which ensures more efficient heat transfer with smaller dimensions.

The length of such batteries varies from 20 cm to 2.5 m, height from 15 cm to 3 m. It is possible to manufacture radiators of any height according to custom sizes. The permissible coolant temperature is 120°C, at a pressure of up to 10 atm.

The Delta Twin M model is also available, which has a similar design, only in a vertical version. It does not provide for the possibility of lateral connection - the pipes are supplied from the bottom in the center. The model range consists of two batteries with a length of 50 cm and 60 cm, height - from 1 m to 2 m.

Purmo Delta Bar

This radiator can be called truly exclusive. It can serve not only as heating device, but also as a decorative table or even a bar counter. It can also be used as a partition for zoning a room.

The supply pipes are hidden from below in the legs and along appearance the device looks more like a designer table rather than a heating radiator. The cover is not included in the package and will have to be ordered separately. The length of such a product without a tabletop is from 70 cm to 1.1 m, height - from 75 cm to 90 cm. Permissible pressure is up to 10 atm., maximum temperature is +120°C.

Purmo Delta Column Bench

Another exclusive development by Purmo designers. At the same time it can serve as a heating device and a decorative bench. As in the previous model, the supply pipes are hidden in the legs, the only difference is the horizontal arrangement of the pipes. The base model is painted in White color, but on individual order Can be painted in any shade from the color palette. The length of such a “bench” is 1.5 m to 1.8 m, height - 20 cm to 35 cm. The maximum pressure is up to 10 atm, the permissible coolant temperature is +120 ° C.

It is worth noting that Purmo provides a 10-year warranty on all radiator models described.

Advantages and disadvantages of Purmo radiators

For the manufacture of Purmo radiators, high-strength steel with a thickness of 1.25 mm is used. Painting of products is carried out using technology used in the automotive industry. Radiators are immersed in a container with a priming solution, and then a special paint is applied under the influence of an electrostatic field. This technology allows the coating to firmly adhere to the surface of the steel, which completely eliminates the possibility of peeling and swelling of the paint due to temperature fluctuations. Products are painted white, but there is a possibility of painting upon individual order. To select a color, the customer is provided with a palette of 700 shades.

Purmo products have a wide range of advantages:

effective heat transfer due to natural convection and infrared thermal radiation;
the simplicity of the design ensures a long service life, since there is simply nothing to break in the device;
various options for supplying heating pipes allow the installation of radiators in any conditions;
Purmo radiators are lightweight and do not require massive brackets for installation;
Due to the small internal volume of the devices, high efficiency is achieved heating system generally;
the cost of metal radiators is much cheaper than similar products made of aluminum;
the aesthetic appearance of the radiators fits harmoniously into the interior of any room;
Purmo radiators have universal design, allowing them to be used in one- and two-pipe heating systems;
quality paintwork reliably protects the outer surface of radiators from corrosion;
It is possible to choose a color in accordance with the design of the room.

Disadvantages of Purmo radiators:

V centralized systems heating service providers drain the coolant during the summer; if air gets inside the device, the metal may corrode.
due to availability large quantity welded seams, radiators do not withstand water hammer well, which limits their use in heating systems operating under high pressure.

Purmo controls the quality of products at all stages of production and is constantly looking for ways to improve products. All Purmo products are standardized and have appropriate certification.

How to match the radiator power to the area of the room?

For single-family houses we offer one- and two-panel PURMO radiators. If the network is laid in the walls of a building, it is necessary to use radiators with side feeding - typ C. If the network is laid in the floor, you can use radiators with a bottom supply - typ CV. The height of the radiators depends on the distance from the window sill to the floor - the bottom edge of the radiator should be no less than 10 cm from the floor, the top edge should be no less than 10 cm from the window sill. The length of the radiator is determined by the heat requirement for heating the room. The heat requirement must be calculated by the plumbing designer.

These calculations are included with most finished projects, and in individual projects they are usually absent. If we do not have calculations, we can use a very simplified method for selecting radiators based on the footage of the premises. This method is fraught with significant errors. Basically, the heat demand is from 60 to 200 W/m2. In houses with good thermal insulation k = 0.3 W/m2K (10 cm of polystyrene foam in multi-layer walls or single-layer walls of the YTONG type 400 type 36.5 cm thick) the requirement will be 60 W/m2 for two-story houses or houses with a residential attic and 70 W/m2 – for one-story houses. In houses without insulation k = 1.2-1.5 W/m2K, the need will be 130-140 W/m2 for two-story houses or houses with a residential attic and 150-200 W/m2 for one-story houses.

When selecting radiators from the table, it is necessary to take into account the calculated parameters of the water in the system central heating and associated correction factors. If the system is powered by a pendant gas boiler, then it will work at parameters 80/60°C or 75/65°C - we select radiators directly from the table.
For parameters other than standard - for example, 90/70°C, we take a correction factor of 0.8 from the coefficient table and multiply it by the heat demand.
Below we provide a diagram for selecting a radiator in a system operating at 90/70°C parameters:
Room 15 m2 in a house with a residential attic
Wall insulation - polystyrene foam 5 cm thick.
The heat source is a suspended gas boiler.
The distance from the floor to the window sill is 85 cm.
Window width – 90 cm.
Q = m2 x 90 W/m2 x 0.8 = 1080 W.

We can choose the radiator C11 6011 - a single-panel radiator with a height of 60 cm and a length of 110 cm or C21s 6009 - a two-panel radiator of the slim type with one convector, a height of 60 cm and a length of 80 cm, or C22 6007 - a two-panel radiator with two convectors with a height of 60 cm cm and length 70 cm.
The length of the selected radiator should not exceed the width of the window, so you need to choose between C21s 6009 and C22 6007 - the choice may be determined by aesthetic considerations.

A more detailed calculation can be obtained from consultant managers

The Purmo company, which produces steel heating radiators, belongs to the European concern Rettig Heating. At the enterprise great attention pay attention to the quality of their products; all required European and Russian certificates have been obtained. The company's range includes both panel and tubular radiators, there are also convectors, heated towel rails, ventilation systems and pipes. In general, if desired, the entire heating system can be made from products from this company.

Panel radiators

For heating appliances of any type, high-quality painting is very important: it not only improves the aesthetic appearance, but also protects the metal from oxidation. Because painting is one key points production. Purmo radiators are painted using technology used in the automotive industry: first they are immersed in a bath with a priming solution, and then a special type of paint is applied in an electrostatic field. As a result, the paint coating adheres perfectly to the metal surface, does not peel off or swell even with temperature changes.

IN basic version All products are painted white, but if necessary, you can order any color from the standard palette, which is more than 700 shades.

Basic model Purmo Compact (Purmo Compact)

This is a panel steel radiator with a corrugated front panel. Side connection - four outputs with internal thread½". Available in the following types: 11, 12 (or 21 - this is the same thing), 22, 33. The first number indicates the number of panels through which the coolant flows, the second - the number of additional convection panels. The more panels, the more powerful the radiator will be, but its depth will also be greater. They can be used in both one-pipe and two-pipe closed systems.

The technical parameters are as follows:

The thickness of the sheet on the panel is 1.25 mm.
The pitch between the vertical channels for the coolant is 33 mm.
Height from 300 mm to 900 mm (in increments of 100 mm).
Length from 400 mm to 3000 mm (up to 1200, increments of 100 mm, then variable).
The power varies over a very wide range: from 289 W (type 11, size 300*400 mm) to 13058 W (type 33, size 900*3000 mm).
The price also depends on the type and size: from 44 to 598 euros.
Ph from 8 to 9.5.
Working pressure - up to 10 Bar, test pressure up to 13 Bar;
Coolant temperature up to +110 o C.
Warranty period - 10 years.

The same model can be produced with a bottom connection. Then it is called Purmo Ventil Compact. In this modification, the coolant pipes can be located at the bottom right or left (specify the type you need when ordering). There is another modification with a bottom connection, Purmo Ventil Compact M. It differs from the previous model in that the bottom entrance is located in the middle. This option is convenient because you can simply remove the pipes and not mount the radiator for now, which is undesirable and problematic with a side connection.

In all models with a coolant supply from below, a thermostatic valve is installed at the factory. The valve is pre-configured, so it does not need to be adjusted (adjustment is needed if its operating mode does not suit you).

Panel radiators "Purmo" with bottom connection are designed for installation in two-pipe systems(for a single-pipe valve, the hydraulic resistance of the valve will be too large). Technical characteristics completely coincide with basic model, there is a difference in price - they are about 20 euros more expensive (the cost of the valve).

Smooth panel battery Purmo Planora (PCV) or Plan Compact

This is a version of a steel radiator with a smooth front panel.

Connection types, dimensions and thermal power and others specifications coincide with the parameters of the base model:

When installing any Purmo radiator with a bottom connection, you need to remember that the supply pipe is on the left, and the return pipe is on the right.

Front panel with horizontal stripes Purmo Ramo Compact

Wide horizontal stripes are stamped on the front panel. This modification is available with side and bottom connections. For the bottom connection the word Ventil is added. Five types are available: 11, 21, 22, 33, 44. Technical characteristics of “Purmo Ramo Compact”:

Special type Purmo Hygiene (Hygiene)

Any of the above options can be produced without additional fin plates. This will be the Purmo Hygiene type. Such radiators are necessary in hospitals and clinics, as well as for those who have allergic diseases.

Perforated metal plates significantly increase heat transfer, but the small distances between them make cleaning difficult and troublesome: no brushes or even a steam generator can clean them, which is unacceptable for medical institutions. Also, without additional panels, the share of radiant heat increases and the percentage of convective heat transfer decreases, which is important for public places. Available in three types: 10, 20, 30.

The “Hygiene” model does not contain additional ribs, so they are easy to wash

There are options Purmo Hygiene - this is a modification of the Compact model with a side connection, Ventil Hygiene - also but with a right or left bottom connection, Ventil Hygiene M - the bottom connection is located in the center of the heater. There are similar models in the Purmo Plan Hygiene modification. There is also a model “Ventil” and “Ventil M”.

Vertical panel radiator Purmo Vertical (Purmo Vertical)

This unusual model will fit well into those rooms where there are few free horizontal surfaces, and large thermal power is required. There are immediately four pipes for the side connection and two located in the center for the bottom. Coolant supply options are shown in the figure.

Types of vertical panel radiator - 10, 20, 21, 22.

Based on the technical characteristics, we can say unequivocally - this is a model for private houses, or for multi-storey houses with an independent heating system, the parameters of which are not higher than those specified for the radiator.

Radiator with ventilation Purmo Air

Modern metal-plastic windows They conserve heat well, but completely block the access of fresh air to the room. Lack of oxygen can lead to poor health and the development of diseases. The Purmo Air radiator is installed on an external wall, a hole is made in it, from where air comes from the street. It goes directly to the built-in filter, and then passes through the radiator and heats up. It turns out that this type of heating device is a miniature heated ventilation system.

Structurally, the Purmo Air system consists of a standard panel radiator 11, 22, 33 and a small set of ventilation and filtering equipment that is installed behind it.

A variety of models and types, capacities and dimensions, the ability to paint the radiator in any color - all this makes it possible to choose a Pumo panel radiator for any room. But once again we draw your attention to the fact that they are only suitable for closed-type systems (with a low oxygen content and a small amount of suspended particles in the coolant). That is, they will perform best in individual heating systems.

Tubular radiators

Steel tubular radiators are very decorative even in the most simple design, but subject to their high-quality production. And Purmo radiators are famous for their quality. Structurally, this type of heating device consists of two section heads (upper and lower), which are stamped from steel sheet. Steel pipes are then welded to them. There can be from two to six rows of pipes (or columns), and the depth of the section changes accordingly. The finished sections are welded together into a single radiator, after which it is tested for leaks, then undergoes anti-corrosion treatment and painted (in any color from the RAL palette).

The appearance and reliability of tubular steel radiators largely depends on the quality of the welds. At Purmo enterprises, laser welding is used, the process is controlled by computers, so the connecting seams are reliable and visually indistinguishable. It seems that this is a single structure.

Delta Laserline and Delta Laserline VT

The classic shape for this type of radiator, but in a special design: the pipes have no round shape, and the cross-section resembles the letter D. This gives an increase in the heating area, and therefore more power with smaller dimensions.

A very wide range of models allows you to choose a heating device for any conditions and any preferences. General technical specifications are as follows:

The Delta Laserline VT modification is a tubular radiator with a bottom connection. The coolant supply pipes can be located on the right or left, as well as in the center (only in versions with an even number of sections). A thermostatic valve is installed on any of the batteries.

Tall radiators Delta Twin M

This tubular radiator is perfect choice in places where there is not enough free horizontal space for a battery of the required power. Only a two-pipe version is available, with a lower central connection. The mounting brackets (four pieces) are welded to the rear panel, the brackets are included.

The technical characteristics of “Purmo Delta Twin” indicate that they can even work in central heating systems, but always with an independent connection (check with the management campaign):

Length 500 mm and 600 mm (10 and 12 sections).
Height 1000 mm, 1200 mm, 1500 mm, 1800 mm, 2000 mm.
Depth - 63 mm.
Thermal power from 753 W (size 500*1000 mm) to 1762 W (size 600*2000 mm).
Ph from 8 to 9.5.
Warranty period - 10 years.

Practical Purmo Delta Bar

This battery can be designed in the form of a table or bench; it can be used as a dividing partition between zones in the room.

Appearance and parameters of Purmo DELTA Bar - radiator-bench (click on the picture to enlarge its size)

The only connection is possible: supply at the bottom left in the outer section (in the left leg), return pipeline at the bottom right (in the right leg). Supplied without top cover. Standard painting is white varnish, upon request - any color from the RAL palette. The pipe connections are hidden, so few will guess that this is not a designer table, but a heating radiator. The technical specifications are as follows:

Length 720 mm (700 mm without tabletop), 920 mm (900 mm), 1120 mm (110 mm).
Height 940 mm (750 mm without tabletop), 1090 mm (900 mm without tabletop).
Depth:
- 4-pipe 224 mm;
- 5-pipe 262 mm.
Thermal power from 1417 W (4 pipes, size 700*750 mm) to 3230 W (5 pipes pipe size 900*1100 mm).
Working pressure - up to 10 Bar, test pressure up to 15 Bar.
Coolant temperature up to +120 o C.
Ph from 8 to 9.5.
Warranty period - 10 years.

Stylish Delta Column Bench

Decorative design radiator that can serve as a stand, table or dividing element for zoning a room.

Purmo DELTA Bench - battery-bench in a different design (click on the picture to enlarge its size)

Unlike the Delta Bar model, the pipes here are arranged horizontally - from four to seven six-column sections. Only bottom connection, supply on the left, return on the right (hidden in the legs).

Length 1535 mm 2835 mm.
Height 387 mm (200 mm without tabletop), 437 mm (250 mm); 487 mm (300 mm), 537 mm (350 mm).

Working pressure - up to 10 Bar, test pressure up to 15 Bar.
Coolant temperature up to +120 o C.
Ph from 8 to 9.5.
Warranty period - 10 years.

When installing under a window sill, the following distances must be observed: from the floor and window sill at least 10-12 cm. If the distance is 7-10 cm, the power must be increased by 5-10%. An even shorter distance will make heating completely ineffective. In this case, you need to choose a radiator with a smaller height.

The pipework must be done in such a way that after completion of the work there is no tension left, either in the pipes or in the fittings. During installation, radiators must not be heated (for example, with a blowtorch).

PURMO Compact C 22

Panel steel radiators PURMO PURMO Compact C 22, equipped with convection elements, the side surfaces are securely covered with safety elements, top part The radiators are covered with a “grill” type bar. The steel radiator has four side connection holes in each corner of the radiator with internal thread G1/2". This arrangement of holes allows you to connect a panel radiator with three possible ways- lateral connection, diagonal and saddle-shaped. This way we can choose the most suitable option connections.

Side connection

This is the most popular solution, allowing radiators to be half-connected on both the right and left. The supply pipe must be connected to the upper radiator fitting, and the return pipe to the lower one. A connection made the other way around will result in a reduction in heat transfer from the radiator by more than 30%.

Cross connection.

Recommended for radiators longer than 2,000 mm, as well as for those whose length is four times the height. The supply pipe must be connected to the right or left upper fitting, and the return pipe to the opposite lower fitting. A connection made the other way around will result in a reduction in heat transfer from the radiator by more than 30%.

Saddle connection.

Most often used in type “C” radiators, when the central heating system is located in the floor. In addition, it can be used in “H” type radiators, and after removing the thermostatic valve – also in CV and HV type radiators. With this type of connection, the heat transfer from the radiator will be approximately 10% lower than the nominal one.

Hydraulic characteristics of Purmo Compact C 22

The resistance to water flow through the radiator depends on the flow of its mass.

For single-panel radiators of types C11 and H10, the pressure drop in the radiator is described by the formula:

Δp = 0.0160 * q2
Kv = 2.5 m3/h

For multi-panel radiators of types C21s, C22 and C33, as well as H20 and H30, the pressure drop in the radiator is described by the formula:

Δp= 0.0105 * q2
Kv = 3.1 m3/h
Where:
Δp is the resistance to water flow through the radiator, expressed in pascals
q is the flow of mass of water passing through the radiator, expressed in kilograms per hour

Radiators of type V and PV are equipped with a built-in thermostatic tap, and therefore their hydraulic characteristics are determined for a radiator kit with a tap.

Thermal power of Purmo Compact C 22 radiators

We have the pleasure to inform you that thanks to the work of our engineers from international group R&D "Rettig ICC" we managed to increase the thermal power of "Purmo" radiators. Improvements concerned the internal design of our products, as well as manufacturing technology.

Studies carried out by the ISO certified research institute in Stuttgart, Germany, have confirmed that their efficiency increases depending on the size of the radiators. So, for example, the thermal power of the C/V 22 600x1000 radiator increased by 3.76%.

Diversity model range often plays the very role that becomes the reason for the purchase. That is, when we come to the store and come across a brand of heating radiator that has several models, we begin to be inclined to purchase one of them. And if in the model range there are types of batteries that are designed for different types premises, then this is a big and bold point and an absolute guarantee that one or more devices will definitely be purchased. This is the case with Purmo radiators, produced by a Finnish company, whose model range includes more than three dozen types (models).

Steel radiators

Let's start with the fact that the Finnish company, by the way, has its own branch in Poland, so this should not confuse you, produces only Purmo steel radiators. Here panel view and tubular.

Tubular radiators for bathrooms

Would like to note heating batteries, which are produced specifically for bathrooms with heated towel rail functions. This group of devices stands apart because it has a number of technical and functional differences:

Firstly, classic version Bathroom radiators are vertical radiators. There are three groups: traditional with tubular sections, with sections offset relative to the center of the radiator, with sections in the form of window blinds. The last look is new for the season.
Secondly, horizontal devices with curved tubular sections. The manufacturer specially produces this type. It is used for design decisions.
Thirdly, a radiator with one vertical collector. Tubular sections are installed horizontally to the side, on which towels of different widths can be hung for drying. That is, the width is not limited by the second collector. This radiator option is non-standard, but very convenient to use.

We must pay tribute that tubular models are used not only in bathrooms. The company today offers quite a wide variety. For example, Delta Bar. This is a tubular radiator with horizontal collectors and vertical pipes, on top of which the tabletop is installed. Essentially, this is a bar counter that can be used for its intended purpose. But at the same time it is also a heating element. With its help, you can divide the space of the room by organizing two separately operated zones. Comfortable, beautiful and functional.

Let us add that Purmo tubular radiators for ordinary rooms are four full-fledged models that differ from each other in design features.

Panel batteries

For many reasons, steel panel radiators “Purmo” are very popular in Russia, which have an unusual range for Russians such as the height of the device: 300, 450, 500, 550, 600 and 900 mm. This creates some inconvenience, but practice has shown that designers can easily cope with this problem. Moreover, Purmo radiators have good technical characteristics, plus acceptable price, that is, the ratio of these two most important indicators is optimal. This is what most often leads to demand.

Let's focus on one model and look at the technical characteristics of the Purmo radiator. To do this, let's take the most popular look– this is the “Compact” model. This device is specially produced for city apartments, it has side connection, the most popular.

Currently, the manufacturer offers three types of heating device: 11, 22, 33. In relation to the height, each type has its own characteristics, which relate to the volume of sections, their heat transfer and installation dimensions. Below is a table where all indicators are collected in one place.

The heat transfer of the device will depend not only on the height, but also on the length of the radiator. Note that the line given size varies from 40 to 300 cm. It turns out that before selecting a heating battery and calculating its power, it is necessary to determine the size of the installation site. That is, the landing dimensions are determined and the dimensions of the radiator itself are selected for them, taking into account its power. The selection is not difficult; for this you will have to use the ratios of all sizes.

There are several examples of this relationship:

Type 11, height 30 cm, radiator length 40 cm - thermal conductivity will be 218.
Type 11, height 900 cm, length 40 cm – thermal conductivity 1304.
Type 22, height 50 cm, length 100 cm – thermal conductivity 1407.
Type 22, height 90 cm, length 300 cm – 7164.
Type 33, height 30 cm, length 100 cm – 1347.
Type 33, height 60 cm, length 100 cm – 2356.

As you can see, the power of the heating radiator varies depending on the size of the device itself.

Heating device design

Purmo Compact radiators can withstand coolant pressure up to 10 atm, while the water temperature should not exceed +110C. For autonomous system heating is an ideal model. In urban conditions, failures in the form of water hammer occur, but Purmo radiators cope with them without problems, because high-quality materials and Newest technologies welding

Attention! The traditional color of Purmo heating radiators is snow-white (RAL 9016). The manufacturer and designers believe that this is the most democratic color that can fit into any interior. But to order, you can paint the batteries in any shade according to the RAL catalogue.

There is another representative of the Purmo model range on the Russian market, which is very popular - this is the Purmo radiator with a bottom connection of the Ventil Compact model. I would like to draw your attention to the configuration of this type:

Mounting brackets.
Plugs.
Mayevsky crane.
Thermovent.

The last device is factory installed only in this model; the rest will have to be purchased separately. But Ventil Compact is not equipped with locking and connecting units; you will have to buy them. By the way, the connection point can be angular or straight, it all depends on where the pipes of the heating system of the house are laid.

Conclusion

It’s not for nothing that Purmo heating radiators are so popular today. This is actually a high quality heating device with excellent heat output. True, the guaranteed service life provided by the manufacturer is only 10 years. But if you use the radiator correctly and achieve good technical characteristics of the coolant, the service life can be almost doubled.
