Warmth from the earth and air: could heat pumps replace our gas boilers?

At least 36,000 heat pumps were installed in homes and businesses across the UK last year, according to the Heat Pump Association, and installations are expected to almost double this year.

The RHI pays out £6,000 in quarterly instalments over a seven-year period to help defray the costs of heat pumps. Ministers are reported to be considering replacing it with a £400m boiler scrappage scheme, which would offer £7,000 grants.

Heat pumps are already popular, but the cost is many times the price of a gas boiler, starting at £6,000 for an air source pump; for a ground source pump the price could climb from £10,000. And many homes need extensive insulation work before they can be installed.
