Annual Energy Use
In the average 3-bed, semi-detached home, heating and hot water account for
- 84% of annual energy use and
- about 50% of annual energy cost
so installing energy efficient systems makes great financial – and environmental – sense.
Most of our Top Tips have a life expectancy of 10 to 20 years, so the savings can really add up:
- Install a modern, A-rated condensing boiler
If the existing boiler needs replacing, then a new A-rated, condensing boiler could save an average home over £150 to £250/year.
- Install a room thermostat and timer
If the home doesn’t have a thermostat, installing one could easily save £90/year. For greater convenience, install a programmable thermostat (= a combined thermostat and timer), or best of all, an internet-connected smart thermostat.
- Install thermostatic radiator valves – and then use them
Installing and correctly using thermostatic radiator valves (TRVs) could save £80/year.
- Turn down the heating
Turning down the room thermostat by just 1°C could save about £80/year.
- Ensure the water in the radiators is clean and air free
Dirty radiator water, with air in it, does not transfer heat from the boiler efficiently. Adding a sludge filter, de-aerator and chemicals could save £40/year.
- Ensure the radiators and pipework are not blocked - Powerflush them!
If radiators, radiator valves or pipework are partially blocked with system sludge, it reduces the efficiency and the system uses more fuel that needed. Removing this sludge could save £80/year.
- Install high efficiency radiators
Modern radiators are quick to heat and much more efficient than older radiators. New radiators could save £4/year per radiator.
- Install radiator reflectors
Radiators fitted on outside walls will radiate some heat externally, even more so if the walls are solid. Radiator reflectors reduce this by reflecting the heat back inside.
- Install a jacket on the hot water cylinder
A hot water tank insulation jacket could save £30/year.
