Introduction

Fitting room thermostats to control room temperatures can be the simp­lest way to save energy and increase comfort. Room thermostats control
the temperature at which your heating system operates, and in doing so
helps save energy by cutting down on wasteful overheating.
Fitting room thermostats also cuts down on heating costs because by
turning down the setting by just 1 °C you can cut the heating fuel bill by
up to 10 %. Reducing wasteful overheating also helps the environment
by reducing harmful emissions.

What is a room thermostat?

The thermostat controls the heating in your home by keeping it at the
temperature you have set. Room thermostats switch off the heat when
the temperature reaches a set point, and switch it on when it falls below.
The heating will not come on if the room temperature is above the room
thermostat set temperature.
Remember that turning the thermostat up will not heat the room any
faster. The higher the thermostat setting the more gas you will use.
