Radiators would have to run 10 degrees cooler under changes to homes needed for Britain to hit net zero, the public has been warned. The Government has said it wants 600,000 heat pumps replacing gas boilers every year by 2028 to help decarbonise the country’s home heating, which accounts for 10 per cent of the UK’s greenhouse gas emissions. But MPs and experts have warned that without a massive programme to address the UK’s draughty homes and scale up engineering skills, people could be left in the cold by the technology, which works by drawing in heat from the air or ground outside. While gas boiler heating systems can pump 60C water into a home’s radiators, the Climate Change Committee, which advises the Government, assumes heat pumps will operate at 50C. To keep homes warm, that may require bigger radiators, underfloor heating and improved insulation, with full modifications estimated to cost on average £18,000. Homeowners will currently have to cover the costs themselves as the government scrapped its grants scheme after just six months.
