How much does underfloor heating cost to run?
Ben Gallizzi, energy expert at Uswitch, said: “Underfloor heating can be a more energy-efficient alternative to radiators, but households will have to consider the cost of installation to see if it’s a worthwhile change.
“Radiators have to reach a high temperature to warm up the air in the room.
“Underfloor heating requires much lower temperatures to work, which means using less energy overall.”
Ben explained that there are two types of underfloor heating – wet systems which pump heated water through pipes under the floor and dry versions that use electric heating wires.
He said: “A dry system uses 150 watts to heat a square metre, so a typical bedroom might require 900W.
“If the heating is on for 12 hours a day, this would cost 27p a day now, and just under 25p from October 1.”
“The wet version is estimated to be about 25% more efficient than running a radiator, but exact savings are hard to calculate as the boiler provides the whole home’s hot water and heating.”
If you have the wet version, then you might want to figure out how much heating and hot water you use before underfloor heating and then watch out for extra costs once you’ve turned it on.
