An air source heat pump repairman from Valiant replaces a Wilo pump inside a Vaillant Arotherm plus 7kw air source heat pump unit at a house in Folkestone, United Kingdom on the 23rd of December 2021. Nearly all new Valiant air source heat pumps come with a 7 year guarantee, this unit broke down and the part was replaced within 48 hours by a Valiant technician. With gas prices increasing and the increasing need to reduce fossil fuel air source heat pumps are slowly starting to replace the gas boiler use in properties in the UK.
