Like your thermostat in your home, your radiator can also have a thermostat. This is called a Thermostatic Radiator Valve (TRV).

Just like your room thermostat, this measures the air temperature in the room. When the room temperature matches the setting on the radiator, the radiator will turn off.

Step-by-step: Using your heating controls

It's easy to set your radiator thermostat:

  1. Make sure your radiator is free from clothing, curtains, or furniture. If the thermostat is covered, it will not be able to accurately record the room temperature.
  2. Make sure your doors and windows are closed as you set the radiator temperature. If you let cold air into the room, the radiator will stay on longer than needed. Also, you will risk increasing your energy use and your energy bills.
  3. On your radiator is a large, numbered dial from 0 to 5. 0 means 10°c, and 5 means 30°c. Set your dial to 3, which will keep the room at 20°c.
  4. When the room temperature matches the radiator temperature, the radiator will turn off.
  5. If you feel that 20°c is not enough, you can increase the temperature. Remember that this will impact your energy bills, so try small adjustments instead.

These thermostats let you set the temperature of each room in your home. That means in rooms you rarely use throughout the day, you don't need to set the temperature as high. You can set the radiators in these rooms at a level of 1 or 2. This will save you money on your energy bills over a 12 month period.
