Heating uses the vast majority of energy consumed in our homes, as these figures from the
Energy Saving Trust demonstrate:
-
Heating 83%
-
Fridges and freezers 3%
-
Cooking 2% Lighting 3%
-
Consumer electronics 2%
-
Electric hot water heating 2%
-
Misc electrical appliances 3%
So it makes sense to look at your heating first and how to stop heat loss from your home if you are serious about using less energy.
Try the following:
-
Turning down your thermostat by one degree will knock about 10% (average °30) off your heating bill
-
Use draught excluders under window sills and doors
-
Cover wooden floors with thick rugs
-
If you feel cold, simply put on more clothes! Lots of small, thin layers will keep you warmer than one bulky jumper
-
Consider heating your home for one hour less each day
-
Turn your hot water thermostat down to 60°C.
Around a third of the heat lost in your home is through the walls. So you could reduce your annual heating bill by £130 to £160 by insulating your walls.
Walls
Houses built between 1930 and 1980 are likely to have cavity walls. Insulation involves injecting a material into the walls from the outside to fill the cavity, which results in the walls retaining more heat. Cavity wall insulation costs between £300 and £500, depending on the size of your home, but there are plenty of grants available.
Roof
Up to 25% of your property's heat could be escaping through the roof, so invest in some loft insulation. The cost for the average family home starts from around £230 which could be subsidised by an energy saving grant, and recouped in just over a year by saving around £200 off the annual heating bill. Topping up existing loft insulation to 270mm is also a good idea.
Windows
Heat is also lost through windows and installing double glazing could reduce the heat lost this way by half. By trapping air between two panes of glass, double glazing creates an insulating barrier that reduces heat loss, noise and condensation.
Boilers
If your boiler is more than 10 to 15 years old it is worth replacing it with a new, energy-efficient model. By replacing an old, heavyweight boiler with a new high-efficiency condensing model, the average family household could save up to £100 to £120 on annual fuel bills. In conjunction with full heating controls, the annual saving could be £190 to £240.
New boilers cost anything from £1,500 to buy and install. If this is too expensive, a £10 British Standard lagging jacket will make your existing boiler more energy-efficient and save about £20 a year.
