Air source heat pumps in Friar's Wash
Air source heat pumps collect heat from outdoor air and bring it inside with electricity running the compressor and fans. It works on the same principle as air conditioning, run the other way, and air-to-air heat pumps are sometimes simply called air conditioning. If the problem is deciding on the outdoor unit position and no space for a hot water cylinder, we can sort it out.

Questions from Friar's Wash
Can I get the Boiler Upgrade Scheme grant in Friar's Wash?
Friar's Wash is in England, where the Boiler Upgrade Scheme runs. The amount depends on the type of heat pump, and the survey confirms which applies. The installer applies, and we are MCS certified.
Is a heat pump in Friar's Wash permitted development?
It comes down to the building and the spot chosen for the outdoor unit. Historic England lists about 4 buildings and structures within half a mile of the centre of Friar's Wash. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights do not reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the planning department at Dacorum council, typically the authority for Friar's Wash.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water replaces the boiler for heating and hot water, while air-to-air heats and cools rooms. The survey helps decide. We install both types.
Do you work in Friar's Wash?
Yes. We work in Friar's Wash and the rest of Hertfordshire, as part of our area across London and the South East. For a fixed-price quote, phone us on 07833 053749 or send an email.
Can landlords and managing agents book you?
Yes. From a single let flat to offices, shops and public buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
Do I need new radiators for a heat pump?
The heat loss survey answers that, room by room. Rooms where the radiator is big enough stay as they are, and any that need upsizing are set out in the quote.
Are you F-Gas certified?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we are Checkatrade members. Engineers who handle refrigerant hold their own F-gas qualifications as well.
