What is a Digital Room

Thermostat?

A room thermostat simply switches the heating system on

and off based on room temperature. 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 house insulation quality is a key factor in heating control.

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 until you are comfortable with the temperature

(20°C is the usual preferred set point). 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 building regulations Part L require houses above a

certain size to have more than 1 heating zone).
