Most households are already trying to cut energy bills by switching off lights, taking showers instead of baths, or timing the heating carefully. But one simple positioning mistake could be silently increasing costs and leaving rooms cold.
When radiators feel slow to heat up even after bleeding and thermostat adjustments, the problem may not be the heating system itself. Energy experts at Fuse said it could be down to how furniture is arranged around them.
Why sofas in front of radiators waste heat
Many households short on space place sofas directly in front of radiators, but the experts recommend moving them away. The area around radiators must stay clear to keep a home warm without turning up the thermostat.
The experts cautioned: "Placing large items like sofas directly in front of radiators creates a physical barrier, trapping heat and preventing it from spreading efficiently into the room." This forces the heating system to work harder and longer to reach the desired temperature, leading to wasted energy and higher bills.
"Obstructing radiators can significantly reduce their efficiency, meaning a portion of the heat generated never properly warms your living space."
Damage to furniture and air quality
Beyond higher costs and chillier rooms, positioning furniture too close to radiators can harm belongings and indoor air quality. Extended heat exposure risks damaging upholstery by causing it to shrink, sag, fade, or crack and warp, depending on the material.
When furniture blocks airflow around radiators, moisture and condensation become trapped, creating ideal conditions for mould to develop and spread.
How much space radiators need
To ensure proper heat distribution, the experts advised keeping at least 30cm of clearance between furniture and radiators. This gap allows warm air to rise and circulate naturally rather than being absorbed by furnishings. Even slightly more space can help a room heat up quicker and more evenly.
The same principle applies to curtains. When heating is on, curtains should not drape over the radiator, as this pushes warmth towards the window. Instead, tuck curtains neatly behind the radiator so it remains fully exposed and heat circulates throughout the room.
Alternatives for small spaces
For those short on space, vertical radiators take up far less horizontal wall space and offer more flexibility for furniture placement. They fit into narrow wall sections, freeing prime wall space for sofas and larger items.
To get the most out of heating, a reflective panel can be positioned behind a sofa to redirect warmth back towards the radiator, or a protective sofa cover can help preserve upholstery.
