Thermostatic Radiator Valves (TRVs)
Thermostatic valves fitted to all your radiators mean that you have ultimate control. You can control the heat given out by your radiators on a room by room basis so you can have different temperatures in each room.
They conserve energy as radiators are not on if they are not required.
I generally use Drayton valves because of their reputation for long life and excellent quality.
Setting my thermostatic radiator valves?
It’s best to set your thermostatic radiator valves to a middle setting and see if the room is warm enough. Then adjust by 1 setting up or down and let the room temperature settle before adjusting again until the room temperature is to your liking. A middle setting corresponds to approximately 20ºC (68F).
It is best not to switch the thermostatic radiator valves fully ON or fully OFF to make the room you are in warmer or cooler – this will waste fuel. Turn it a little way and let it do the work.
