Room Thermostats

These prevent your home from getting warmer than necessary. They turn the heating on until the room reaches the temperature you have set, and then off until the temperature drops.

Room thermostats need a free flow of air to sense the temperature, so they should not be blocked by curtains or furniture, or placed near heat sources that could give them false readings.

Your room thermostat should be set to the lowest comfortable temperature, which for most is between 18°C and 21°C. If you only have a single-room thermostat for the whole house, for every degree you increase the temperature, it will increase the heating bill by about 10%.

You don’t need to turn your thermostat up when it is colder outside; the house will heat up to the set temperature regardless. It may take a little longer on colder days, so you might want to set your heating to come on earlier in the winter.
