Reducing heat loss in your home is important for lowering your heating bills, reducing your carbon footprint, and improving your energy efficiency. We’re specialists in energy-efficient heating solutions, but effective heating starts with a well-insulated home.
Cavity walls, usually found in homes built after 1920, consist of two layers of brick with a gap (or cavity) between them. Without insulation, these walls can let significant amounts of heat escape your home. Insulating cavity walls can reduce heat loss by up to 35%.
A professional will inject insulation material (such as mineral wool or foam) into the cavity through small holes drilled in the wall. This generally a quick and cost-effective installation which can help to significantly reduced your heating bills.
Older homes (pre 1920’s) often have solid walls. These lose more heat than cavity walls. Solid wall insulation can be applied internally or externally:
Installing solid wall insulation can reduce heat loss by up to 45%. Internal insulation can also be a great option for properties in conservation areas.
Uninsulated floors can account for up to 10% of all heat loss in a home. Both suspended timber floors and solid concrete floors can benefit from insulation. If you have suspended floors, insulation is placed between the floor joists, with a membrane to prevent draughts. If you have solid floors, insulating material can be added on top of the floor with a layer of flooring on top. Insulating your floors can reduce draughts from below, make your floors warmer to walk on, and increases your home’s energy efficiency.
Up to 25% of a home’s heat can escape through the roof. Roof and loft insulation is one of the most cost-effective ways to improve your home’s energy efficiency.
Installing roof and loft insulation can help keep heat inside during the colder months, and keep heat out during the warmer months. It’s generally a long-lasting solution, and can provide a quick return on investment.
Sealing any gaps in windows, doors, and even chimneys that let cold air in and warm air out is an affordable way to reduce home heat loss. You should consider draught proofing:
You can use foam strips or brushes for windows and doors, flexible sealant for cracks in flooring and skirting boards, and letterbox and keyhole covers. These are inexpensive, easy to DIY solutions that can provide immediate improvements in your warmth and comfort.
Windows and doors can account for up to 20% of home heat loss. Consider upgrading to double or triple glazing – these windows have multiple panes of glass with gas or air in between to reduce heat transfer. If you live in a listed building where replacing windows isn’t feasible, you could consider secondary glazing. Modern insulated doors are designed to minimise heat loss, and adding draught-proofing measures improves their efficiency even further. These insulation measures can reduce condensation on windows, improve sound insulation, and cut your heating costs.
We recommend a combination of the above measures to make your home as energy efficient as it can be. Pairing your well-insulated home with energy efficient heating solutions such as our German A++ ELKATHERM® electric radiators and Sunamp hot water batteries can help you maximise energy bill savings. Opting for a full HeatElectric system: Qcells solar system with ELKATHERM® electric heating and Sunamp thermal store for hot water can provide exceptional energy bill savings whilst also reducing your carbon footprint.
