How boiler controls could help with fuel bills
Use boiler controls to maximise energy efficiency
Even though condensing boilers are already over 90% efficient, the performance of your heating system can be further improved using boiler controls.
How can heating controls help with fuel bills?
Using the right boiler controls with a condensing boiler offers annual savings of up to £235 (source: EST*) and can help to ease your home’s impact on the environment.
Heating controls give you the freedom to decide how your home is heated, making it warm when you need to, but switching off when you don’t.
Making small adjustments to your boiler controls can help to save money. By turning your room thermostat down by just 1 degree, you could save £55* annually.
Improving the energy efficiency of your home could also help, for example by installing cavity wall insulation.
Which heating controls do I need?
All new or replacement boilers require a minimum level of controls installed alongside them, either:
- A timer or programmer with a room thermostat and thermostatic radiator valves (TRVs)
- A programmable room thermostat and thermostatic radiator valves
If your heating system includes a hot water cylinder, that will require a thermostat too.
What is a timer?
A boiler timer is a basic device that allows you to set times for your central heating.
What is a programmer?
A boiler programmer allows you to set different times for heating and/or hot water.
What is the difference between timers and programmers?
A timer operates your heating system at the same times every day whereas a programmer allows different heating times for different days of the week to suit your lifestyle.
What is a room thermostat?
A room thermostat enables you to set the target temperature for a room.
Room thermostats are usually best positioned in the hall or landing. They should be sited away from direct sunlight and clear of curtains and furniture.
What is a programmable room thermostat?
A programmable room thermostat enables you to set different room temperatures for different times of the day and night.
When set up correctly, a programmable room thermostat prevents the system from having to heat the house from a ‘cold start’. The control always maintains a temperature within the property and this ensures that the boiler is only ever ‘topping up’ the temperature in the home. As a guideline, target temperatures should be set at 21 C for comfort temperature and 15 C for economy temperature.
What is a thermostatic radiator valve (TRV)?
TRVs allow you to control the temperature of each room individually, thus helping to improve comfort in your home as well as saving money and energy. Most radiators will be fitted with these. Ideally, TRVs should be well exposed and not obstructed by curtains or blocked by furniture.
