This is a stark contrast to the 82.5% efficiency of gas boilers highlighted in previous studie
Tamsin Lishman, CEO of Kensa, said: “This new research shows beyond doubt that heat pumps are the most efficient way of heating homes, three to four times more efficient than gas boilers.
“As a manufacturer and installer of ground source heat pumps, it’s pleasing to see real-world data confirming the technology is the most efficient heating technology available, over 40% more efficient even than air source heat pumps.
Heat pumps hold their own in winter
“Importantly, the report shows ground source heat pumps perform well even when temperatures drop below zero, meaning reduced electricity demand and less pressure on the grid. This is a critical finding for how we achieve the mass roll-out of heat pumps, with millions of homes poised to switch to electrified heating.
“However, even with these efficiencies, today’s energy prices still mean it’s only slightly cheaper to run a heat pump than a gas boiler in a typical British home.
“At a time when we need to be weaning ourselves off fossil fuels, it doesn’t make sense that electricity is still four times the price of gas. It’s critical the government acts now to remove the levies artificially pushing up the price of electricity.
“Combine the continually improving efficiencies of heat pumps with lower power prices, and we’ll see the significant real-world savings consumers can make by switching to low-carbon heating.
“With this and ending the installation of gas boilers in new homes, the government can normalise heat pumps in UK homes and kick start the transition to clean affordable heat.”
