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 dierent 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 ow of air to sense the temperature, so they must not
be covered by curtains or blocked by furniture. Nearby electric res, televisions, wall
or table lamps may also prevent the thermostat from working properly.
A room thermostat simply switches the heating system on and o 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 o 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 aect how quickly the room cools
down. Setting a programmable 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 nd 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.
