Clivet R290 heat pump replaces LPG
23rd August 2026
UK: The first Clivet Edge Pro R290 heat pump installation in the UK has been installed in an historic Lincolnshire home to replace a 40kW LPG boiler.
The 16kW Edge Pro installation has taken place at Gorse Cottage near Boston, the home of Simon Wardle and Diane Saunders of Ultimate Renewables Supplies, Clivet’s sole UK distributor.
Parts of Gorse Cottage date back to 1844, with several later extensions creating a five-bedroom, multi-generational property incorporating a two-bedroom annex.
The previous system included a 40kW LPG boiler and large LPG storage tank. However, detailed room-by-room calculations established an actual design heat loss of just 14.58kW, enabling the system to be correctly specified with the 16kW Clivet unit.
The Edge Pro is said to be capable of producing water temperatures of up to 80°C, achieves A+++ heating efficiency at 35°C, and can operate in outdoor temperatures down to -25°C.
Despite the age and complexity of the property, the retrofit required the replacement of just three radiators.
The complete installation also incorporates Clivet Adia Zero Disrupt, a 300-litre Supercoil cylinder and whole-house booster pump, with equipment neatly housed in a purpose-built insulated external plant room.
As an eligible off-gas-grid property moving from LPG to a heat pump, the project also benefited from the enhanced £9,000 BUS grant.
