Heating Controls

Heating controls allow you to decide how your home is heated, by controlling your boiler and making it warm when you want it but switching off when you don′t.

A properly controlled system should have :

  • A programmer.
  • A room thermostat.
  • A combined programmable room thermostat (instead of separate programmer and room thermostat).
  • A cylinder thermostat (if you have a hot water cylinder).
  • Thermostatic radiator valves (TRVs).

More advanced controls, such as boiler energy managers are also available. Knowing how to get the most out of your current heating controls will benefit you financially and help reduce energy wastage. Read on to find out about each of the different types of heating controls and what they do.

What is a programmer?

Programmers allow you to set ′On′ and ′Off′ time periods. Some models switch the central heating and domestic hot water on and off at the same time, while others allow the domestic hot water and heating to come on and go off at different times.

If everyone with gas central heating installed a high efficiency condensing boiler, we would save enough energy to heat millions of homes

What is a room thermostat?

A room thermostat simply switches the heating system on and off as necessary. It works by sensing the air temperature, switching on the heating when the air temperature falls below the thermostat setting and switching it off once this set temperature has been reached.

If you are too warm, try reducing your thermostat by 1°C. This can cut up to 10% off heating bills and save energy

What is a programmable room thermostat?

A programmable room thermostat lets you choose what times you want the heating to be on and what temperature it should reach while it is on. It will allow you to select different temperatures in your home at different times of the day and days of the week. This means you can save money and energy by not heating your home unnecessarily

What is a cylinder thermostat?

A cylinder thermostat switches on and off the heat supply from the boiler to the hot-water cylinder. It works by sensing the temperature of the water inside the cylinder.

Control individual room temperatures with thermostatic radiator valves

What is a thermostatic radiator valve (TRV)?

TRVs sense the air temperature around them and switch the radiator off and on accordingly. They help improve comfort in your home by allowing you to set different temperatures in different rooms. This also helps to save money and energy.

Please note: TRVs cannot turn off the boiler when the whole house is warm. To do that you will need a room thermostat as well. The radiator in the room with the room thermostat should not normally have a TRV but if it does, keep the TRV on the maximum setting and adjust the room thermostat as explained in the instructions.

If you install the right heating controls, you could save up to 40% on your fuel bill.

To make sure you are doing all you can to ensure your heating controls are working efficiently, refer to the manufacturer′s user guide for more advice.

* Caution - programmable thermostats, room thermostats and TRVs all need a free flow of air to sense the temperature. They must not be covered by curtains or blocked by furniture. Nearby electric fires, televisions, wall or table lamps may prevent them from working properly.
