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 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.
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.
