Boiler Controls

Save money with the best heating controls

Out-of-date central heating system components and controls can lead to wasted energy, costing you money. They can also create potential heating problems.


  • hot water cylinder supplied by gravity-fed water - stored water is slow to reheat

  • no cylinder thermostat - stored water can become too hot and risk scalding

  • no cylinder insulation - heat is wasted through the surface of the cylinder

  • no room thermostat - rooms are too hot or too cold

  • lack of thermostatic radiator valves (TRVs) - excessive room temperatures and poor heating system balancing no boiler interlock - this means the boiler stays hot and cycles unnecessarily during programmed heating periods.


You might not notice these issues in your home, but they'll be wasting your money in the long run. To find out how much an inefficient boiler could be costing you, and to work out if you need a new boiler, take a look at our guide on boiler energy efficiency. 


Get the best heating controls to save you money


The type of heating controls you need will depend on the type of heating system you have and whether your hot water comes direct from your boiler or via a hot water cylinder.


When you have a new boiler or heating component installed, you should discuss which controls you need for your home with your heating engineer 


There are five main types of heating control:


  • timer – turns your boiler on or off at set times

  • room thermostat – measures how warm your room is and adjusts the boiler operation accordingly programmer – lets you set different times and temperatures for different days of the week

  • thermostatic radiator valves (TVRs) – allow you to adjust the temperature of individual radiators and turn them off completely

  • smart thermostats - allow you to control the temperature in your home when you are not there
