Thermostatic Radiator Valves (TRVs)
It is a common misconception that the numbers displayed on thermostatic radiator valves relate to the radiator’s temperature.
These numbers are instead used to convey the room’s temperature.
A TRV is a self-regulating valve that controls a room's temperature by managing the flow of hot water to a radiator.
It is estimated that the use of thermostatic radiator valves can help you save up to 40% on your energy consumption (energysavingtrust, 2022) , resulting in significantly lower energy bills.
Aside from the economic benefits, setting your ideal room temperature by selecting the number on the TRV will boost your comfort levels. For example, you may wish to increase the level of heat in your living room but find it more comfortable to sleep in a cooler bedroom
What should I set it at?
Here’s an estimated guide of the room temperatures relating to the numbers displayed on TRVs:
0 – Off
* – 7°C
1 – 10°C
2 – 15°C
3 – 20°C
4 – 25°C
