Energy Efficient Heating Controls

70% of homes in the UK  have inadequate heating controls. Contact us today and we can start reducing your energy bills by installing effective controls.

When it comes to heating your home efficiently – wasting as little fuel and heat as possible – then a full set of energy saving or heating controls is just as essential as having the right kind of boiler. We can offer advice on what controls can help save you money and heat your home from simple controls to learning thermostats such as the Nest thermostat or Weather Compensation.

So what are Energy or Heat Saving Controls?

As their name implies, heating controls allow you to choose when the heating is on, how warm it is, and where you want the warmth. They will also make sure that the boiler is only turned on when it needs to be.

Fitting the correct heating controls could typically save you around 17% of your heating bill. What’s more, installing a condensing boiler along with a full set of heating controls could save as much as 40% of your heating fuel bill. This is a considerable sum of money which is going to rise as gas and oil prices continually rise.

Once you have installed the controls, it is important to ensure they are used correctly. This is the easiest way to keep your rooms at a comfortable temperature and in doing so, they’ will help to reduce your household’s fuel bills and CO2 emissions, too.

What makes a full set of heating controls?
A properly controlled heating system should typically have:
  • A time programmer
  • A room thermostat
  • A combined programmable room thermostat
  • A cylinder thermostat if your home has a regular condensing boiler with a hot water cylinder.
  • Thermostatic radiator valves (TRVs).


Are you making the most of your heating controls?

You may already have a full set of heating controls in your home – but are you getting the best from them?nest

Take a little time to find out what each control does using our quick guide below and you could save money and valuable energy. If you do have any of these controls already refer to the instruction manuals that came with them, for specific advice on your particular make and model. If you don’t have any manuals to hand, copies can usually be downloaded from manufacturer’s website.

What is a programmer?

Programmers allow you to set when the heating and hot water come ‘On’ and go ‘Off’ again. By installing a programmer, and heating your home and hot water only as and when necessary, you will save energy and money.

What is a room thermostat?

A room thermostat constantly measures the air temperature of a space and can be set to whatever temperature suits you best. They are usually in halls, stairs or landing areas to sense the temperature of a home’s main living spaces. When the temperature falls below the setting, the thermostat switches on the central heating; once the room reaches the set temperature, the thermostat switches the heating off. Please note that the timer or programmer needs to be switched on for the thermostat to work.

 What is a programmable room thermostat?

A programmable room thermostat lets you choose the times you want your home to be heated and the temperature you want it to reach while it is on. In other words, it allows you to heat rooms or the whole house to different temperatures in your home at appropriate times of the day and week. And again, by heating your home and hot water only as and when necessary, it can save energy and money too.

What is a cylinder thermostat?

A cylinder thermostat keeps a constant check on the temperature of the water in a hot-water cylinder. It switches the heat supply from the boiler on and off as necessary to keep the water at a set temperature.

Installing a cylinder thermostat could save you up to £40 and 110kg of CO2 a year.

What are thermostatic radiator valves (TRVs)?

TRVs sense the air temperature around them and regulate the flow of hot water entering the radiators to keep a set temperature in a room. Again, they can  save money and  energy – by allowing temperatures in some rooms than in others, and to turn off the heating in rooms that aren’t used.

In the majority of cases TRVs can not turn off the boiler when the whole house has reached the right temperature. To do that, you will need a room thermostat as well. Radiators in the  space containing the room thermostat should not normally have TRVs. But if they do, you should keep the TRVs on their highest possible settings, and set the room thermostat to the  required temperature instead. By                          installing TRVs, you could save around £20 a year and around 45kg of CO2 a year.
