Danfoss markets products through wholesalers and installers. Please contact your preferred installer for advice on your heating installation. You need a professional to help you get things right.
Danfoss is a well-known brand available from all professional installers. Please contact your local installer to learn more about, and order Danfoss thermostats.
Danfoss recommends you contact a professional installer. A professional installer can advise you on replacing radiator thermostats and choosing the correct thermostats for your house and your needs. A professional installer can also advise you about optimising your heating system in other respects.
The manual radiator valve does not open or close by itself and it does not use the advantage of free heat. A thermostatic radiator valve automatically regulates the room temperature and uses the advantage of free heat. If you replace manual radiator valves with the new electronic living eco or living connect, you can save up to 46% energy. If you replace thermostatic radiator valves, you can save up to 23% energy.
Please contact your local installer to enquire about prices in your area.
Regular Danfoss thermostats use liquid or gas to regulate their valves – they operate mechanically. living design also operates mechanically, whereas living eco and living connect use a motor and electronics. This ensures more precise regulation and the possibility to create programs with set-back periods – thereby ensuring energy savings.
Yes, we recommend the new living by Danfoss radiator thermostats for all types of flats and single-family houses as the new thermostats provide you with an optimised energy use. living design, living eco and living connect fit on the most common valve types: RA and M30. living eco and living connect can even be mounted on very old types of valves (called RA/V or RA/VL), but Danfoss recommend you replace these old valves with Danfoss RA valves with pre-setting for even better energy optimisation. Your professional installer can advise you about radiator thermostats and radiator valves.
You probably have different needs, preferences and lifestyle from those of your neighbours. This is exactly why we are introducing a product family for you to choose from. If you want total convenience and easy access to energy savings, or you are passionate about new technology, you should choose Danfoss Link + living connect. However, living eco is the right choice if you are looking for an intelligent means to control your heating in the most cost-effective way with the shortest payback time. If you prefer using your radiator thermostat like you used your old one, and are simply keen on aesthetics, living design is ideal.
On your old radiator thermostat, you can not see if it is controlling accurately. Old radiator thermostats typically have a wear-out effect, meaning that their reaction slows down and they become less precise over time. One consequence of this is wasted energy. Radiator thermostats older than 15 years always have a certain wear-out effect. On the other hand, living eco and Danfoss Link + living connect have functionalities you do not find on traditional radiator thermostats.
A number of factors in the heating system and the room can influence the thermometer readings, e.g. the size of the radiators, if the living thermostat is mounted horizontally or vertically, if cold drafts from windows occurs, how the furniture is arranged, etc. Or the temperature difference can simply be caused by thermometers being inaccurate and having different positions in the room.
Make sure your furniture are not preventing the radiator heat to circulate in the room and try to place your thermometer close to the living thermostat.
The version or model number of your living eco is printed on the inside of the battery cover.
The newest version is called 1.24.
No. As a general rule pressing the plus (+) or minus (-) button will toggle between winter and British summer time.Please refer to the user instructions for your specific model.
If the programmer is failing to work there is no mains power getting to the unit. Check the mains power supply.
There are older versions of the 103E7 and 102E7 (purchased before 1994) which pre-date the instructions on the website.
No. These devices use unique identity coded radio signals that ensure secure communications.
Replacement slider switches for the 922 are not available. A direct plug-in replacement for the 922 and 972 is the FP975.
For these models of programmers, the battery is used as a back-up power reserve to hold the programmed settings during a power-cut. If the battery symbol is flashing then this means that the mains power is not getting to the unit. You will need to check the mains power supply to the unit. The battery is non-replaceable as it is soldered into the unit.
The battery in the 702 programmer is only used to hold the programmed settings during a power-cut. If there is a power-cut you will have to re-programme the unit. The Varta 600DK battery is no longer available. Varta stopped manufacturing it 10 years ago, and we cannot source a replacement manufacturer.
The following Danfoss controls are standard battery powered models. They all take 2 x high quality alkaline AA size batteries - TP5000, TP7000, HC6000, WP75-RF and RET-B.

Heat pump systems can be over four times as energy efficient as the most efficient gas or oil boiler. Instead of burning a fuel and producing the associated emissions, they simply move energy that already exists – stored solar energy.
Seasonal performance express the performance of a heat pump over a full year given the heating distribution system, hot water system and the actual customer demand. Proper dimensioning, installation and commissioning are needed to obtain the highest possible seasonal performance.
Seasonal performance is the standard measure for Danfoss heat pumps when designing and building heat pumps, as seasonal performance is the real measure of efficiency.
This choice is dependent on various factors; your local authorized installer will be able to guide you through the entire process.
Either in your utility room or basement. You could even put it out in the garage if you so desired.
No, they hum like a large refrigerator. The units we supply have had many years of research and development factored into their manufacturing, including major noise and vibration reduction.
Yes, under floor heating, radiators or a mix of both can be used for heat distribution in your building. In commercial buildings, air distributed systems can be used.
With the correct design and equipment, all domestic hot water requirements would be provided by the air source or ground source heat pump throughout the year.
Yes. Thousands of these systems have been installed for many years in some of the most northern parts of Scandinavia, where the winters are very harsh and long. The key is the design and specification process, so the system provides enough energy for the application.
Yes, of course. And there are many alternatives – from simple additions to complicated systems – that provide extra energy. Talk to your installer.
Yes, a properly commissioned Danfoss control system will work perfectly fine with single room controls. Contact your authorized installer for assistance.
There is no general answer to this question. The cost depends on your house, energy consumption and what features you want. Your local distributor can give you a precise quotation depending on your circumstances.
There are many manufacturers with a wide range of products available. Danfoss is the only one in the heating and refrigeration industry with 80+ years of experience and expertise in designing, manufacturing and installing heat pump systems.
Our first heat pump with integrated hot water tank was manufactured in 1973, and we have been researching and improving our technologies ever since. Danfoss is ideally situated to provide valuable advice and information in all areas of the heat pump market, from product selection to system design and commissioning.
The principle of floor heating is to heat the room from below, which is an exceptionally comfortable heating method. Floor heating pipes can be embedded directly into the concrete slab (heavy/wet floor heating), or special heat distribution panels can be used (e.g. SpeedUpTM) located closer to the finished floor (light/dry floor heating).Please note: Up to 95% of all systems are installed as heavy floor heating. Contact your installer if you are in doubt as to whether your system has been installed as heavy or light floor heating.Heavy floor heating has a relatively long response time. It will generally take about 1-2 hours per adjusted degree for the system to reach the desired room temperature. On very few days in the year, typically during transitional periods, temperatures slightly over or under those set must be expected. This occurs when the weather changes faster than the controller is able to keep up, e.g. in the event of sudden periods of intense sunlight or sudden, significant drops in temperature. Light floor heating has a relatively short response time. It will generally take about 20 minutes for the system to achieve the desired room temperature for each adjusted degree.
Yes, you can, as long as you keep certain things in mind. Heavy floor heating We recommend one long temperature reduction period (at least 7 hours) with a slightly lower economy temperature setting. The difference between the comfort and the economy temperature must not be more than 1-2 degrees. Lowering the temperature too much will prevent the system from reaching the low temperature and no energy saving will be achieved. If you attempt to achieve too great a reduction in temperature you risk that the heat source (e.g. boiler) will work inefficiently. This will have a negative impact on your energy consumption.Light floor heatingWe recommend setting a lower economy temperature for one or two extended periods. The difference between the comfort and the economy temperature must not be more than 3-4 degrees, as otherwise the system will not be able to keep up. If you attempt to achieve too great a reduction in temperature you risk that the heat source (e.g. boiler) will work inefficiently. This will have a negative impact on your energy consumption.
When the battery-operated units are close to running out of power, an alarm will be issued. The system will not “forget” anything even if a unit temporarily loses power. In the event of a battery-operated unit running completely out of power, the unit will set the room to a certain temperature before the batteries die.If you experience that battery life time is less than 2 years, there can be several possible causes:• Rechargeable batteries are being used. Solution: Switch to non-rechargeable alkaline batteries.• Old batteries (batteries also have an expiry date). Solution: Switch to non-rechargeable alkaline batteries.• Only applies to wireless systems: Unstable wireless network. Solution: Contact your installer. If the wireless network is unstable, the room device will communicate more often than normal, resulting in increased battery consumption.
Why maintain a high room temperature when you’re not at home? Lowering the room temperature by one degree will reduce your heating costs by approx. 5%. For this reason it makes perfect sense to use temperature setbacks. If you have hydronic floor heating, you should not lower the temperature by more than 1-2 ˚C, as the cooling/heating time is very long.
Room temperature too high:• Only applies to battery operated devices: When batteries are running low, the device will automatically set the room to a certain temperature before the batteries die. Solution: Replace the batteries• Someone may have set the room device too high. Solution: Reduce the room temperature• Strong solar gains in low energy homes. Solution: Solar screening / blindsRoom temperature too high:• The heat source is providing no or insufficient heat. Solution: Check if the heat source is active and increase the supply temperature. Note: Increasing the supply temperature will make the heat source operate less energy efficient – especially a heat pump. It may also result in more fluctuating room temperatures. • The heat source itself is operating with an automatic temperature reduction schedule. Solution: Deactivate temperature reduction schedule on the heat source if it conflicts with the desired operation. • Defective circulation pump. Solution: Check the circulation pump. If necessary, contact your installer.• The room thermostat has been set too low. Solution: Set the thermostat to the desired temperature, at ½-degree intervals, if possible.• If the room has never been able to reach the desired temperature, it may be due to an incorrectly dimensioned heat emitter (too long or limited pipe circuits) or insufficient hydronic balancing (insufficient water flow to the floor heating circuit). Solution: Contact your installer
