How To Set Your Thermostatic Radiator Valves

  1. Play around until you find the right temperature for you
  2. Resist the temptation to open the valve all the way when you go into the room in the morning and find its too cold
  3. Avoid setting the valve to minimum when it’s too hot
  4. Let the thermostatic bulb do its work naturally

Taking the below table as a guide, here are recommended approximate settings for each type of room:

115°CUnoccupied room

Please note: This table is just an approximate guide to heating temperatures and settings.

*Valve position corresponds to a frost protection temperature and position 3 is approximately 20°C.

Top Tips

  1. An ideal heat setting is between 18-20 degrees. The higher the temperature the more the cost will be per kW/h.
  2. By turning your thermostat down, even reducing the temperature by 1°C could save you energy and money, without you noticing any difference.
  3. By using the manual setting on your thermostat, you can control the times your heating is turned on. Turn your heating off during the night. You will be under the covers and the room will not need to be too warm during the night.
  4. Draw the curtains. Especially at night, to keep the warmth in and the cold out. Also, tuck your curtains behind the radiators if possible.
  5. Avoid drying clothes on your radiators. This lowers the amount of heat released by the radiators, so the boiler has to run for longer to achieve the same room temperature, thereby using more fuel overall.
  6. Keep furniture away from radiators. The foam in upholstered furniture is a very effective heat insulator and prevents it getting into your room.
  7. Use the sun. It’s the most readily available source of heat and it’s the cheapest! When it’s sunny, make the most of it by opening your internal doors and let the warm air flow through your home.
  8. You could put an extra layer of clothing on which will help to keep you warm.
