Heating Controls

Heating Controls

The right Heating Controls will let you keep your home at a comfortable temperature without wasting fuel or heat - so you'll reduce your carbon dioxide emissions and spend less on heating bills.

If your home is heated by a system of water-filled pipes and radiators running from a boiler (a 'wet' central heating system,). Your full set of controls should ideally include a boiler thermostat, a timer or programmer, a room thermostat and thermostatic radiator valves (TRVs).


Whatever the age of your boiler, the right controls will let you set your heating and hot water to come on and off when you need them, heat just the areas of your home you want, and decide how warm you want each area to be. Here are the average savings you could make in a typical three-bedroom semi-detached home, heated by gas:

  • Install a room thermostat if you didn't have one before: £70 and 280kg carbon dioxide a year.

  • Fit a hot water tank thermostat: £30 and 130kg carbon dioxide a year.

  • Fit a hot water tank insulation jacket: £45 and 170kg carbon dioxide a year.

You can also make savings by using your controls more effectively:

  • Turn down your room thermostat by one degree: save around £65 and 260kg carbon dioxide a year.

You can upgrade or install heating controls without replacing your boiler, and it's a particularly good idea to think about this if your controls are over 12 years old. Room thermostats, for example, are much more accurate than they used to be.

How it works

Room thermostats prevent your home getting warmer than it needs to be: they will 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 must not be blocked by curtains or furniture, or put near heat sources.

Thermostatic Radiator Valves (TRVs) do not control the boiler: they just reduce the flow of water through the radiator they are fitted to when the temperature goes above a certain setting. Set them to the level you want for the room: a lower setting uses less energy and so will save you money.

Zone control help save money by not overheating parts of your home that are unoccupied or need lower temperatures – bedrooms or rooms with lots of glazing, for example. You can have separate heating circuits with their own programmer and room thermostat (or programmable room thermostat) or set zones by using thermostatic radiator valves (TRVs).
