Insulate for the Greatest Savings
A sure-fire way to lower your heating bills is to improve the insulation in your property. Whether it’s the attic, walls or pipes, proper insulation makes a difference.
Insulate the attic. You can save heating costs by laying a fibreglass insulation blanket over the joists or filling the spaces between joists with loose-fill granules. Since up to 25% of your home’s heat is lost through the roof, you should recoup the cost within a few years.
Check existing insulation. Older houses often have only a thin layer of insulation. Ideally, it should be at least 20 cm (8 in.) deep. Top it up by 10-15 cm (4-6 in.) and you could be more comfortable and save money on heating costs.
Insulate the pipes. Insulate hot-water pipes with electric heat tape or flexible foam tubing, which you can buy from a plumbers’ supply or DIY store. You could save more than just the cost of lost heat-proper insulation helps to stop pipes freezing and bursting in winter.
Insulate the hot-water tank. Put an 8 cm (3 in.) thick insulating jacket around your hot-water tank to reduce heat loss by up to 75%. Check the owner’s manual to make sure a blanket is recommended for your model.
