Turn down your room thermostat by 1°C and it could save you 10% on your fuel bill. But don't skimp on heat if you are elderly or if your health is at risk.
Make sure your heating system is not set to come ‘ON' too early. Setting it to come ‘ON' about 30 minutes before you get up would normally be adequate.
Similarly, the heat left in your heating system at the end of the day can still be used. Setting your heating to go ‘OFF' about 30 minutes before you go to bed could save you money without affecting your comfort in any way.
It is usually more efficient to use a lower home heating setting for a longer time. This is cheaper and more comfortable than running heating for short bursts at high temperatures.
If you don't have double glazing, consider the use of low cost secondary glazing, such as plastic sheet (e.g. Polycell) or “cling-film” type. These are not normally permanent, but do cut down heat loss through the glass, and can help eliminate draughts. You can fit them for winter and remove them for the rest of the year if you wish.
Use gas fires or individual room heaters when there is no need to heat the whole house. Fires and heaters are normally designed to keep the individual room at a comfortable temperature.
Don't open doors or windows to cool down a room which is too warm - turn down the heating thermostat instead. This is heat that has to be paid for, so it is better to use only that which is needed rather than using it to no effect.
Putting reflective foil behind radiators reflects valuable heat back into the room where you need it, rather than heating the wall behind the radiator. This is even more cost effective when the radiator is sited on an uninsulated external wall.
Don't overheat unused rooms - use only minimal heat. But make sure you keep the fabric of the building warm enough to prevent condensation problems occurring.
Draw the curtains at dusk. Make sure curtains don't cover radiators as the heat will escape through the window rather than heating the room. Thick, lined curtains also help retain heat.
Don't put furniture in front of radiators and heaters - heat is not cheap and should be used for heating people, not three piece suites!
Fill in gaps between floors and skirting boards using modern sealants which will ensure draught-free rooms. Also make sure your loft hatch fits snugly - don't forget that warm air rises and will find a way out if it can.
