Radiator thermostats

Self-regulating thermostatic radiator valves can save a lot of energy compared to manual valves. Studies show that the energy savings potential going from manual to thermostatic is between 30-36%. Going from a 15+ year old thermostat to electronic thermostats opens for another 23% savings to tap. The newer the technology, the more savings. Each leave does not represent an exact figure but gives a rough illustration on the energy savings performance.

Comfort performance is closely linked to the thermostats ability to keep the temperature as close as possible to the set point. Two main factors affect the performance; precise temperature control and reaction time. Our thermostats span from 1-22 min response time depending on the filling inside the bellow.
Each house symbol on the overview does not represent an exact figure but gives a rough illustration on the added performance on temperature regulation and comfort. Learn more about the effect of response time below.

Response time is the time it takes before the thermostats detects a change in temperature, and then starts to compensate for it by opening or closing the valve, to either lower or increase the temperature in the room, to reach the desired set temperature. Not to be mixed with the time it takes for the thermostat to restore the set temperature in the room.

Response time is closely linked to the filling medium inside the bellow of the thermostat. Wax is the slowest (40 min) where Danfoss does not have an offering. Then comes liquid (15-22 min) and our premium gas (10 min) which is the fastest reacting mechanical thermostat on the market. Finally, electronic components as the top-performer with 1 min response time.
The faster the response time, the better the comfort.

Tells you what tool is required to install the thermostat. The symbol with the click-lock function represents our patented tool-free installation feature that allows you to install the thermostats using only your hands. This patented solution also makes sure that the clamping force is adequate, so it will not damage the thermostat or the valve but still securing a very firm grip.

Provides you with a quick overview of which connection types fit with our thermostats, so you easily can pick what type of thermostat to choose for replacement. In the mechanical range, you get the most options from the Aveo^TM and the Aero^TM which fits RA, RAV, RAVL and RTD valves. From the electronic range, you get a broad range of options with the adapter system that fits 90+% of all radiator valves out there.
