What is a room thermostat? … an explanation for householders
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.
Turning a room thermostat to a higher setting will not make the room
heat up any faster. How quickly the room heats up depends on the
design of the heating system, for example, the size of the boiler and
radiators.
Neither does the setting affect how quickly the room cools down.
Turning a room thermostat to a lower setting will result in the room
being controlled at a lower temperature, and saves energy.
The heating system will not work if a time switch or programmer has
switched it off.
The way to set and use your room thermostat is to nd the lowest
temperature setting 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 18oC and then turn it up by
one degree 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.
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 (TRV’s) on individual radiators. If you
don’t have TRV’s you should choose a temperature that is reasonable
for the whole house. If you do have TRV’s 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 TRV’s.
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 prevent the
thermostat from working properly.
