That makes it a practical fit for homes and spaces without a wet heating system: flats on storage or panel heaters, extensions and garden rooms, open-plan living areas, and homes where installing radiators and pipework would be very disruptive. One outdoor unit can serve a single indoor unit, or several rooms through a multi-split system, with each room controlled separately.
Top-floor rooms in County Armagh that overheat in summer gain from the cooling an air-to-air system provides. Installers in County Armagh plan condensate drains and pipe covers so indoor and outdoor runs stay neat. Extensions and garden rooms in County Armagh that are hard to connect to the main heating can have their own air-to-air unit.
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

Air-to-air heat pumps questions
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.
Can an air-to-air heat pump heat my water?
No. An air-to-air heat pump heats and cools the air in rooms but does not produce hot water. You need a separate source, such as an existing immersion cylinder, a hot water heat pump or an electric water heater. If you want one system for heating and hot water, an air-to-water heat pump with a cylinder is the alternative.
