...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 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 find 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 18°C – 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.
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 prevent the thermostat from
working properly.
