What is a room thermostat?
... an explanation for householders. 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.
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 aect 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.
