BBC article 9 hours ago............
Heat pumps are still too expensive and too few people know about them, the government has been warned.
Despite its target, only 55,000 heat pumps were sold in the UK in 2022. Sales must increase dramatically, said the UK's spending watchdog.
To meet UK climate change targets, the government wants to install 600,000 low-carbon heat pumps annually by 2028.
The government told the BBC it was "helping rather than forcing families to install heat pumps".
The National Audit Office (NAO) said ministers were optimistic to think that target could be reached by 2028.
It urged the government to increase public awareness of the green technology and work to reduce costs.
Its director Simon Bittlestone told the BBC: "The government has got some big questions to answer about how it plans to decarbonise home heating."
Heating in UK homes produces 18% of the country's greenhouse gas emissions, which are responsible for climate change.
Heat pumps use electricity rather than gas like boilers and, as the UK produces more electricity from renewable energy, fewer emissions will be created by heating our homes this way.
