Home heat loss facts and figures There can be miscomprehension about where most heat is lost in the home, so we thought it would be helpful to give some facts and figures about this topical issue. It’s a common belief that heat mainly flows upwards. Heat can flow in any direction, which means that any part of our homes can lose heat. The four main sources of heat loss in the home are: 1️⃣ Walls – account for the greatest heat loss, at 35-45%. 2️⃣ Roof – if you live in a house, rather than a flat with a home above you, heat loss through the roof can be up to 20%, especially when insulation is absent or minimal. 3️⃣ Windows and doors – a typical house loses 10% of its heat through its windows and the same is true of doors. 4️⃣ Floor – in older homes and those with poor insulation, the floor can account for up to 10-20% of heat loss. Addressing heat loss in your home through adequate insulation will reduce the amount of fuel that is required to heat it, which has a direct impact on reducing energy bills.
