For the user
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.
What is a room thermostat? ... an explanation for householders
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.
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.
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.
