A rural 1844 home has transitioned from LPG to a Clivet Edge Pro R290 heat pump, delivering high-performance residential heating and lower carbon output.
A historic rural property dating back to 1844 has successfully converted its primary heating setup from liquid petroleum gas (LPG) to an air-source heat pump (ASHP). The installation utilised the Clivet Edge Pro, a high-performance residential unit that operates using R290 refrigerant to supply both heating and cooling functions.
Retrofitting older properties that lack access to the mains gas network presents specific technical challenges. Historically, rural off-grid homes have relied heavily on oil or LPG tanks, both of which suffer from high fuel cost volatility and substantial carbon emissions. The application of monobloc heat pumps capable of running on natural refrigerants like R290 allows installers to achieve high flow temperatures without requiring extensive internal system overhauls.
R290 propane refrigerant is gaining traction across the heating sector due to its low Global Warming Potential (GWP) rating of just 3. This property makes it compliant with tightening environmental regulations while maintaining strong performance metrics in colder conditions.
What does this mean for a UK tradesperson or DIYer actually buying this kit — does it change what they should pay, buy, or watch out for? For heating engineers and plumbing contractors, this case study demonstrates that propane-based R290 monoblocs are now fully viable alternatives to off-grid LPG or oil boilers in solid-wall retrofits. Installers looking to capture business under the Boiler Upgrade Scheme should note that units using R290 allow higher flow temperatures, which often saves customers from having to swap out every radiator in an older property. When purchasing through trade merchants, factors to evaluate include the pre-charged monobloc format, which simplifies outdoor siting, though installers must ensure they carry the correct flammability safety training required for handling propane systems.
