An air-to-air heat pump takes heat from the outside air and delivers it straight into rooms as warm air through indoor units, usually mounted high on a wall. The same system can run in reverse to cool rooms in summer. Unlike an air-to-water heat pump, it does not use radiators or underfloor heating and does not heat a hot water cylinder.
Top-floor rooms in Argyll and Bute that overheat in summer gain from the cooling an air-to-air system provides. Flats in Argyll and Bute on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework. A survey in Argyll and Bute covers indoor unit positions, pipe routes and hot water for homes across Argyll and Bute.
Who it suits
- Households that already have, or will add, a separate source of hot water
- Flats and apartments with storage or panel heaters
- Rooms that get too hot in summer as well as cold in winter
- Homes where fitting radiators and pipework would be very disruptive
Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Argyll and Bute can apply to Home Energy Scotland for a grant of up to £7,500 towards a heat pump, with up to £1,500 more for eligible rural and island homes, plus an optional interest-free loan of up to £7,500.

Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Scotland has its own permitted development rules for air source heat pumps and its own building standards, so we confirm what applies to your property at survey.

Air-to-air heat pumps questions
How do I look after an air-to-air system?
Clean the indoor unit filters regularly, typically every few weeks during heavy use and following the manufacturer's guidance, and keep the outdoor unit clear of leaves and snow. Annual servicing is recommended and is often a condition of the manufacturer's warranty. Any work on the refrigerant circuit must be done by an F-gas certified engineer.
Is there a grant for air-to-air heat pumps?
In England and Wales, yes: the Boiler Upgrade Scheme includes a grant of £2,500 for air-to-air heat pumps in homes, from 28 April 2026. The MCS-certified installer applies to Ofgem and deducts it from your quote, subject to the scheme's conditions. The scheme does not cover Scotland or Northern Ireland; in Scotland, Home Energy Scotland has its own rules.
Can air-to-air heat pumps cool as well as heat?
Yes. Most air-to-air systems can reverse their cycle to cool and dehumidify rooms in summer, which makes them useful for loft rooms, south-facing extensions and home offices that overheat. Cooling uses electricity, so running costs rise if it is used heavily. You control heating and cooling for each room separately.
Are air-to-air heat pumps suitable for flats?
Often, yes. They need no radiators, pipework or cylinder, so they suit flats heated by storage or panel heaters. You need a position for the outdoor unit, such as a balcony, wall bracket or ground-floor yard, and leaseholders normally need the freeholder's or management company's consent. Planning rules for flats differ by nation, so we check what applies at survey.
