Where is energy lost most in home?
Up and down the country millions of homes are losing significant amounts of money in waste energy. From the attic, to windows, doors and other wastes of energy – we look at the areas where the most waste is lost and what homeowners can do to fix these black holes.
The majority of energy wasted escapes from the roof of a property – hot air rises! Insulating the attic or crawlspace of a home can help trap more heat in the areas needed. For older homes adding insulation is the single most cost-effective way to dramatically reduce heating bills.
Upgrading the cavity insulation in walls also stops energy escaping and reduces heating bills. Walls make up the majority of a home’s outer surface area, giving a lot of potential for energy and money to be wasted. Choosing insulation with a higher value may be of help too.
Are you considering adding insulation to existing walls without the cavities for large scale insulation? Use sprayed-foam insulation. Not only does it mould into any shape, it can be used in the tightest and smallest of gaps.
Seal Gaps in Doors
An estimated 15-30% of a home’s total heating costs are lost through doors and other drafty entrances. Something as simple as placing draft excluders, weather-stripping and caulking over open spaces can help significantly reduce wasted energy.
No one likes standing on a cold floor, and draughty floors are almost unbearable! Insulating floors can stop heat escaping and keep inhabitants toasty without a massive fuel bill. If you’re considering more of a major overhaul, installing under floor heating in conjunction with a boiler or heat pump allows effective home heating – possibly getting rid of radiators for good.
Every Leak Helps
Heat can be lost anywhere from wall sockets to fireplaces. Investing in foam gaskets can help stop waste by blocking off gaps in the walls. Closing a fireplace’s damper when it’s not in use can also stop heat and energy escaping.
If a home is losing a significant amount of heat, it may be time to consider upgrading the boiler. The boiler in most UK homes tends to be a mains gas boiler. A new energy efficient condensing boiler should be roughly 90% efficient, converting 1 unit of gas into 0.9 units of heat.
Boilers that are older than 10 years old may not be as efficient, possibly operating at 65% or less Efficiency.
Other heating solutions available include air and ground source heat pumps which benefit from the Renewable Heat Incentive Scheme (RHI). This pays for every unit of hot water produced. RHI also benefits those who install biomass boilers. These run on biomass pellets which are carbon neutral – meaning homes can be heated in an energy efficient way!
