The advantages of our products
Saving up to 46% of energy
Radiator thermostators allow you to spend exactly the amount of energy that is currently necessary to maintain a comfortable room temperature. Different thermostatic elements cope with this task in different ways. Compared with the manual adjustable valve, the thermostats with liquid or paraffin filling make it possible to save 31%, with gas filling - 36%. The use of electronic radiator thermostats Danfoss Living ECO allows you to save up to 46% of energy to heating.
* According to a study conducted by the Rhine-Westphalical Technical University,
g. Achen, Germany.
Fast reaction
DANFOSS RA series thermostators are equipped with gas filling bellows. The heat capacity of gas is significantly less than liquids and, moreover, paraffin. As a result, gas regulators with gas filling react much faster to change the temperature indoors. Therefore, Danfoss thermostators maintain a temperature with greater accuracy and provide greater energy savings. Radiator thermostat with a gas-filled thermostatic element ("gas") are patented and manufactured only by Danfoss.
Simple installation and configuration
A set of adapters will allow you to install Danfoss Living Eco thermostat on most thermostatic valves present in the market. Ensure yourself, looking at this short video.
Reliable work
Danfoss thermostators are fully adapted to work in Russian conditions. It makes it possible to approve this to us more than 40 years of experience of operating thermostators in Russia. For the first time in Moscow, Danfoss thermostators were installed in 1964 in the hotel "Russia", where they served before her demolition
Safety thermal heads for heating radiators
In thermal heads for radiators heating Danfoss. Living ECO provides a blocking function from children. The study of the surrounding world will be safe even for the smallest.
Comfort in all rooms
The amount of heat required by each room changes during the day. In the morning the sun shines in the windows on the eastern side of the house, at noon on the southern, evening on Western. If you control the heating of the whole house around the temperature in the same room, the temperature will change during the day.
Now you can buy a thermostat with modern design.
Red Dot - known worldwide "quality mark" in the field of industrial design. Only exceptionally from the point of view of aesthetics and functionality products are obtained by this high evaluation. In 2010, Danfoss was awarded Red Dot award for the development of the Living series thermostats.
In the countries of the post-Soviet space, up to 40% of energy resources goes to the needs of heating and ventilation of buildings, it is several times more than that of advanced European countries. The issue of energy saving costs sharply, more than ever, especially against the background of constant increase in the cost of energy carriers. One of the devices that save thermal energy in the house is the thermostat for the battery whose installation can reduce heat consumption up to 20%. But for this, it is necessary to correctly select regulators to the heating system and perform their installation, which will be told in this article.
The principle of operation of the thermostatic valve
The first thermostats for radiators designed to maintain a permanent temperature in the room were invented back in 1943 by Danfoss, she also owns the championship in the production and sale of such devices. For this reason, our article will rely on the materials and recommendations of the company Danfoss, whose many years of experience is not subject to doubt.
For the years since the invention, the thermostators for radiators were changed and became such as we know them. Structurally, they consist of two main elements: valve and thermal heads that are connected by a locking mechanism. The appointment of the thermal heads - perceive the temperature ambient And to regulate it, influence the actuator - the valve, it overlaps the flow of the coolant entering the heating device.
This method of regulation is called quantitative, since the device affects the flow rate of the coolant passing into the radiator. There is another method - high-quality, the temperature of the water in the system changes with it. This carries out a temperature controller (mixing unit), installed in a boiler room or thermal point.
To understand the principle of operation of the thermal heads, it is proposed to study the scheme of the device shown in the context:
Inside the element housing is a bellows filled with a heat-sensitive medium. It happens two types:
- liquid;
- gas.
Liquid bellows are easier in the manufacture, but losing gas to speed, so the latter got very widespread. So, with an increase in air temperature, the substance in the closed space expands, the bellows is stretched and presses on the valve stem. That, in turn, moves down a special cone that reduces the valve flow cross section. As a result, the flow rate of the coolant decreases. When cooling the ambient air, everything occurs in the reverse order, the number of flowing water grows to a maximum, this is the principle of operation of the thermostat.
Depending on the type of heating system and the installation conditions of the device, the sets of the thermal head can be used to control the flow of the coolant. different combinations. In one-tube heating systems, it is recommended to install valves with elevated throughput and low hydraulic resistance (marking Production of Danfoss - RA-G, RA-KE, RA-KEW).
The same recommendation concerns two-pipe samotane systems, where the coolant circulates naturally, without compulsory motivation. If the heating scheme is two-pipe with circulating pumpYou should choose a valve with the ability to adjust the bandwidth (Marking Danfoss - RA-N, RA-K, RA-KW). This adjustment is quite simple and the special tool is not needed for it.
When a question with the selection of the valve is resolved, you need to decide on the type of thermal head. They are offered in the following versions:
- With an internal thermoelement (as in the diagram presented above).
- With a remote temperature sensor.
- With an external regulator.
- Electronic (programmable).
- Antivandal.
An ordinary thermostat for heating radiators with an internal sensor is received to the installation, if it is possible to arrange its axis horizontally so that the air of the room freely washed the body of the instrument, as shown in Figure:
Attention! It is not allowed to install a thermostat for a battery in a vertical position, the thermal stream, rising from the feed pipe and the valve body, will influence the bellows, as a result of which the device will not work correctly.
If horizontal head mounting is not possible, it is better to purchase a remote temperature sensor in a set with a capillary tube with a length of 2 m. It is at such a distance from the radiator that this device can be placed by attaching it to the wall:
In addition to the vertical installation for buying a remote sensor, there are other objective reasons:
- heating radiators with temperature regulator are behind dense curtains;
- in the immediate vicinity of the thermal heads pass pipes with hot water or there is another source of heat;
- the battery is under a broad windowsill;
- the internal thermoelement enters the area of \u200b\u200bthe draft.
In rooms with high battery interior requirements, often hide under decorative screens from various materials. In such cases, the thermostat that fell under the casing registers the temperature of the hot air accumulating in the upper zone and can entirely block the coolant. Moreover, it is completely closed access to head control. In this situation, the choice should be made in favor of the remote controller combined with the sensor. Options for its placement are shown in Figure:
Electronic thermostats with display are also two types: with a built-in and removable control unit. The latter is characterized by the fact that the electronic unit is disconnected from the thermal head, after which it continues to function as usual. Assigning similar devices - adjustment of the temperature in the time of day in accordance with the program. This allows you to reduce the heating power in working timeWhen there are no one at home and in other similar cases, which leads to additional energy savings.
When there are small children in the house, which everyone wants to try their handles, it is better to establish an anti-vandal type thermostat with a casing that protects the settings of the device from unqualified intervention. This applies to the thermostats facing other public buildings: kindergartens, schools, hospitals, and so on.
How to install a thermostat on the battery
The first recommendation is not to put thermal heads on all heaters within sight. Here the following is the following: the regulation must be subjected to radiators whose total power is 50% or more of all in the same room. For example, when there are 2 heater in the room, then the thermostat should be equipped with 1 battery, whose power is greater.
Council. If pig-iron radiators are used as heating devices, then maintaining the microclimate using thermostatic valves will be ineffective. The fact is that work cast-iron batteries Very inertial, after overlapping the coolant flow, they emit heat for a long time and vice versa for a long time they accelerate. Installation of valves does not make sense, you will only spend your time and means.
The first part of the device is the valve - it is recommended to mount on the supply feed pipe at the time of connection of the radiator to heating system. In the case when it is required to embed it into the collected system, the feed liner will have to be dismantled. It will deliver some difficulties if the connection is executed steel pipesMake a tool for cutting pipes and cutting threads.
After the thermostat on the heating battery is set, the thermal head is mounted without a tool. It is enough just to combine tags on the housings and smoothly pressing the head in the nest. The signal will serve as a fixing mechanism.
It is a bit more difficult to install an anti-vandal thermostat, for this you will need a hex key of 2 mm. By combining the required tags, as shown in the diagram, you need to press the thermal head, and the hexagon is tightened to the locking bolt on the side.
Installation of the remote sensor and the regulator is carried out on the parts free of the interior parts and furniture, placing them at an altitude of 1.2-1.6 m from the floor, as shown in the diagram:
First, the mounting plate is attached to the wall to the wall, and then the housing is snapped by simply by pressing it. The capillary tube is fixed to the wall of plastic homutics, as a rule, they are included with the product.
In addition to the standard temperature adjustment in the heads, the thermostat is set to the maximum and minimum limits, on which the rotation of the wheel becomes impossible. This contains restrictive pins that are in the rear of the product. You need to pull out one of them and after debugging the system insert into the hole under the appropriate label:
Conclusion
To make a selection of the thermostat - the task is simple, it is important to understand what the valve is purchased under which heating system is purchased and know where it will be. Definitely recommended programmable devices, as the most economical.

The main task of any heating system is to provide a comfortable air temperature in the room. This temperature can be different depending on the purpose of the room, but if mandatory condition It is its immutability during the day, the thermostat becomes an indispensable structural element of the heating device.
Danfoss radiator thermostat consists of two parts: valve and thermostatic element (thermal heads). Inside the thermostatic element is a thin hermetic cylinder - a belliff filled with liquid or gaseous heat-sensitive working substance. When the temperature is raised, the bellows stretch and moves the rod associated with it, which presses on the rod in the valve, and the valve reduces the coolant flow into the radiator. When the temperature decreases, the process goes in reverse order. Thus, the thermal head is the control mechanism, and the valve is executive.
Manufacturer: Danfoss (Denmark).
Danfoss radiator thermostators valves
Valves of radiator thermostators are divided into:
- valves for a two-pipe pumping system of heating (type Ra-n) of increased resistance with the installation device of their bandwidth for performing hydraulic balancing of the pipeline system;
- Valves of increased bandwidth type Ra-G for pumping single-tube or two-pipe gravitational heating system.
Valve housings Danfoss are made of brass. The compound provides a simple and accurate mounting of the thermostatic element on the adjusting valve. To identify Ra-N valves, their protective caps are painted in red, and Ra-G is in gray.

Thermostatic elements of Danfoss.
Thermostatic elements (thermal heads) Danfoss are automatic temperature control devices intended for a complete set of radiator thermostators.
The thermostat equipped with a thermostatic element maintains a constant temperature in the room at the desired level in the range from + 5 ° C to + 26 ° C with an accuracy of ± 1 ° C.
It should be remembered that thermostators are mostly regulatory reinforcement but not shut-off (With the exception of the thermostats RA2940 and RAW 5110), so if you need to disassemble the radiator, the thermal head should be replaced with a bronze shut-off handle, which will ensure the complete overlap of the coolant flow.

By installing thermostat, it should be remembered that the effect of their use will be tangible if they control radiators with low thermal inertia. Practically, these are all the well-known types of modern radiators besides cast iron. The latter, due to the large mass of the cast iron and the water will be heated and cool very slowly, reducing the control effect.
RLV shut-off and connecting valves are designed for lateral connection to the radiator of pipelines of a two-pipe heating system. We are produced in direct and corner execution.

Thermostatic elements of the RA 2000 series
Thermostatic elements of the RA 2000 series are automatic temperature control devices designed to complete the RA radiator thermostators. The radiator thermostat is a proportional direct-action air temperature regulator with a small proportion zone, which is currently equipped with systems for the heating of buildings of various purposes. The thermostat Ra consists of two parts:
All thermostatic elements can be combined with any regulating valves of type RA. Clip connection provides simple and accurate mounting of the thermoelement on the valve. The protective cover of thermoelements RA 2920 and RA 2922 prevents their unauthorized dismantling and reconfiguration to unauthorized persons. The technical characteristics of the radiator thermostators of the type RA correspond to European standards EN 215-1 and Russian GOST 30815-2002.
Specifications of thermostatic elements of the RA 2000 series
The main device of the thermostatic element is a bellows that provides proportional regulation. The thermoelement sensor perceives the change in the ambient temperature. The bellows and the sensor are filled with an easy-to-sleep liquidity and its pairs. The adjusted pressure in the bellows corresponds to the temperature of its charging. This pressure is balanced by the power of the tuning springs. With increasing air temperature around the sensor, part of the fluid evaporates, and the pressure of vapors in the bellows grows. In this case, the bellows increase in the volume by moving the valve spool towards the closing of the hole for the coolant duct into the heater until the balance between the spring force and the vapor pressure is reached. When the air temperature decreases, the pairs are condensed, and the pressure in the bellows decreases, which leads to a decrease in its volume and the movement of the valve spool towards the opening to the position in which the equilibrium of the system will again be established. Steam filling will always be condensed in the coldest part of the sensor, usually most remote from the valve body. Therefore, the radiator thermostat will always respond to changes in room temperature, which does not feel the temperature of the coolant in the underwater pipeline. However, when the air around the valve is still heated by heat, given by the pipeline, the sensor can register a higher temperature than indoors. Therefore, it is recommended to establish thermostatic elements to eliminate this influence, as a rule, in a horizontal position. Otherwise, it is necessary to apply thermoelements with a remote sensor.
Select the type of thermostatic element
Thermostatic elements with built-in sensor
When choosing a thermostatic element, it should be guided by the rule: the sensor should always react to the air temperature in the room.
Thermostatic elements with a built-in sensor should always be arranged horizontally so that the ambient air can freely circulate around the sensor. Do not install them in a vertical position, since the thermal effect on the sensor from the valve body and the heating system pipe will lead to the incorrect functioning of the thermostat.
Thermostatic elements with a remote sensor
Thermostatic elements with a remote sensor should be applied if: o Thermal elements are closed with a deaf curtain; o The heat flux from the heating system pipelines affects the built-in temperature sensor; o The thermoelement is located in the draft area; o required vertical installation of thermoelement. The remote sensor of the thermostatic element must be installed on the furniture-free and curtains or on a plinth under the heating device if there are no pipelines of the heating system. When installing the sensor, the capillary tube should be pulled out to the required length (maximum of 2 m) and fasten it on the wall using the accompanying brackets or a special pistol.
Thermostatic elements of the RAW series
Thermostatic elements of the RAW series - devices of automatic temperature control, designed to complete the RA radiator thermostators. Radiator thermostat is a proportional direct-acting air temperature regulator with a small proportionality zone, which is currently equipped with systems for the heating of buildings of various purposes. The RA type thermostat consists of two parts: a universal thermostatic element of the RAW series and an adjusting valve with a pre-adjustment of the RA-N bandwidth (for two-pipe heating systems) or Ra-G (for a single-tube system).
The program of the production of thermostatic elements of the RAW series includes:
The thermostatic elements of the RAW series are equipped with system protection devices from freezing, fixing and restricting the temperature setting. RAW 5012 is equipped with an ultra-thin capillary tube with a length of 2 m, which is swept inside the sensor housing and connects a remote sensor with a thermostatic element. In the process of installation, the pipe is pulled into the required length. Clip connection provides simple and accurate mounting of the thermoelement on the valve.
The technical characteristics of radiator thermostators with thermoelements of the RAW series correspond to European standards EN 215-1 and Russian GOST 30815-2002.
In order to prevent unauthorized dismantling, the thermoelement can be fixed on the valve using a special retainer (see additional accessories).
Specifications of thermostatic elements of the RAW series
The main device of the thermostatic element is a bellows that provides proportional regulation. The thermoelement sensor perceives the change in the ambient temperature. The bellows and the sensor are filled with a special heat sensitive liquid. The adjusted pressure in the bellows corresponds to the temperature of its charging. This pressure is balanced by the power of the tuning springs. When the air temperature is raised around the sensor, the liquid is expanding, and the pressure in the bellows grows. In this case, the bellows increase in the volume by moving the valve spool towards the closure of the heat carrier duct into the heating device until the equilibrium between the spring and the fluid pressure is reached. When the air temperature decreases, the liquid begins to shrink, and the pressure in the bellows decreases, which leads to a decrease in its volume and the movement of the valve spool towards the opening to the position in which the equilibrium of the system will again be established. To eliminate influence warm air From heating nozzle of the heating device, it is recommended to set thermostatic elements, as a rule, in a horizontal position. Otherwise, it is necessary to apply thermoelements with a remote sensor.
Thermostatically elements of the RAW-K series
Thermostatic elements of the RAW-K series are automatic temperature controllers with a small proportionality zone. RAW-K are designed to install on the thermostators of the thermostators of HEIMEIER, OVENTROP or MNG, built into the design of steel panel radiators type Biasi, Delta, Dianorm, Diatherm, Ferroli, Henerad, Kaimann, Kermi, Korado, Purmo, Radson, Superia, Stelrad, Veha, Zehnder-Completto Fix. The thermostatic element of the RAW-K series has a liquid sensor with a temperature setting range of 8-28 ° C and is equipped with a device for protecting the heating system from freezing.
The company "Danfoss" produces 3 modifications of the thermoelements of the RAW-K series:
RAW-K 5032 is equipped with an ultra-thin capillary tube with a length of 2 m, which is swept inside the exhaust sensor housing, connecting it with the thermostatic element working bellows. In the process of installation, the tube is pulled into the required length. The thermostatic elements of the RAW-K series comply with European standards EN 215-1 and Russian GOST 30815-2002.

The thermoelectric mini-actuators of the TWA series are designed for a two-position control of various control valves in heating systems and heat-drying of local ventilation plants.
The drive is equipped with a visual indicator of the stroke, which shows, in which position is the valve - closed or open.
TWA actuators depending on the modification can be used with valves of the RA, RAV8 and VMT series manufactured by Danfoss, as well as with HEIMEIER, MNG and OVENTROP valves, having a thread for fastening the drive M 30 x 1.5. In the case of applying a drive with other types of valve valve, the valve must be tested for compatibility of geometry and ensuring its closure. Power supply voltage - 24 or 230 V. Valves can be normally closed in the absence of voltage (NC) and normally open (NO). In addition, the normally closed drive with feed voltage 24 V is supplied with a limit switch (NC / S).
The thermostat valves with the pre-tuning RA-N and RA-NCX DU \u003d 15 mm (chrome)
RA-N and RA-NCX regulating valves are assigned to use in two-pipe water heating pumping systems.
RA-N is equipped with a built-in device for preliminary (mounting) adjusting its bandwidth within the following ranges:
Ra-n and Ra-NCX valves can be combined with all the thermostatic elements of the RA, RAW and RAX series, as well as with thermoelectric drive TWA-A.
To identify RA-N and RA-NCX valves, their protective caps are painted in red. The protective cap should not be used to overlap the coolant flow through the heating device. Therefore, the handle should be applied (code number 013G3300).
Valve housings are made of pure brass with nickel coating (Ra-N) or chrome (RA-NCX).
The technical characteristics of the RA-N and RA-NCX valves in combination with thermostatic elements of the RA, RAW and RAX series correspond to European standards EN 215-1 and Russian GOST 30815-2002, and the size of the connecting thread is the HD 1215 standard (BS 6284 1984). All radiator thermostators manufactured by Danfoss are manufactured at factories with ISO 9000 quality certificate (BS 5750).
To prevent deposits and corrosion, RA-N and RA-NCX thermostat valves should be used in water heating systems, where the coolant meets the requirements of the Rules technical exploitation Electrical stations and networks of the Russian Federation. In other cases, it is necessary to contact the company "Danfoss". It is not recommended to use compositions containing petroleum products (mineral oils) to lubricate the valve parts.
Setting on the calculated value is made easily and accurately without the use of special tools. To do this, make the following operations:
Pre-configuration can be performed in the range from "1" to "7" at intervals of 0.5. The "N" position valve is fully open. Installation should be avoided on a dark zone scale.
When the thermostatic element is mounted, the pre-tuning is hidden and, thus, protected from an unauthorized change.
The thermostat valve with a pre-tuning RA-N with a compound fitting
The RA-N valve is designed for use in two-pipe water heating pump systems with copper or stainless steel pipelines. To connect the valve with a pipeline with a pipeline, special crimping tools are required. Valve Case for appearance and the technical characteristics are identical to the standard valves Ra-N DN \u003d 15 mm. Ra-n can be used with any types of thermal static elements of the RA or RAW series, as well as with thermostatic elements of a special design of type RAX and thermoelectric TWA-A thermoelectric drive.
The RA-N control valve is equipped with a built-in device for preliminary (monkent) adjusting its KV bandwidth in the range from 0.04 to 0.73 m3 / h.
To identify valves, the protective cap is painted in red. The cap should not be used to overlap the adjustable medium. To this end, it is necessary to use a special metal handle (code number 013G3300). The valve body is made of nickel-plated brass DZR, and the pressure pin is made of stainless steel. The pin does not require lubrication over the entire life of the valve. The gland seal can be replaced without emptying the pipeline system. Ra-n should be used in water heating systems, where the coolant meets the requirements of the maintenance rules of electrical stations and networks of the Russian Federation. In other cases, it is necessary to contact the company "Danfoss". It is not recommended to use formulations containing oil products (mineral oils) to lubricate the valve parts.
The thermostat valve with increased bandwidth RA-G
The valve thermoregulating with increased bandwidth RA-G is designed for use, as a rule, in single-pipe systems of water heating with a pumping circulation of the coolant that meets the requirements of the technical operation of electric stations and thermal networks of the Russian Federation. The valve is not recommended to be used if impurities of mineral oil are present in the coolant.
RA-G is equipped with a seal that can be replaced without emptying the heating system. The pressure pin in the gland is made of chrome steel and does not require lubrication over the entire life of the valve. All performances of RA-G valves are combined with any thermostatic elements of the RA series.
Ra-G valves are supplied with gray (for identifying) protective caps that should not be used to overlap the coolant flow. Therefore, a special metal service locking handle should be applied (code number 013G3300).
A set of X-TRATM thermostatic reinforcement for heated towel rails and design radiators.
The thermostatic X-TRA ™ kit is specifically designed for heated towel rails. It consists of a valve of the thermostator, the thermostatic element and shut-off valve with drainage function. Innovative self-adhesive connection of valves to the radiator is carried out using a thread one second inches. Valves and thermoelement are available in white, chrome-plated and steel versions, suitable for most heated towel rails. This kit is the perfect ending of the heated towel rail. Attractive and compact design allows you to install the thermostat under the heated towel railway parallel to the wall, eliminating random strikes on it.
