What is a Room Thermostat?

If your heating system is a boiler with radiators, there will usually be only one room 

thermostat to control the whole house. But you can have different temperatures 

in individual rooms by installing thermostatic radiator valves (TRVs) on individual 

radiators.

If you don’t have TRVs, you should choose a temperature that is reasonable for the 

whole house. If you do have TRVs, you can choose a slightly higher setting to make 

sure that even the coldest room is comfortable, then prevent any overheating in other 

rooms by adjusting the TRVs. 

Room thermostats need a free flow of air to sense the temperature, so they must not 

be covered by curtains or blocked by furniture. Nearby electric fires, televisions, wall 

or table lamps may also prevent the thermostat from working properly.

A room thermostat simply switches the heating system on and off as necessary.

It works by sensing the air temperature, switching on the heating when the air 

temperature falls below the thermostat setting, and switching it off once this set 

temperature has been reached.

Setting a room thermostat to a higher temperature will not make the room heat up 

any faster.  How quickly the room heats up depends on the design & size of the heating 

system.

Similarly reducing the temperature setting does not affect how quickly the room cools 

down. Setting a room thermostat to a lower temperature will result in the room being 

controlled at a lower temperature, and saves energy.

The way to set and use your room thermostat is to find the lowest temperature settings 

that you are comfortable with, and then leave it alone to do its job.

The best way to do this is to set the room thermostat to a low temperature

– say 18°C , and then turn it up by 1°C each day until you are comfortable with the 

temperature. You won’t have to adjust the thermostat further. Any adjustment above 

this setting will waste energy and cost you more money.
