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.
Extensions and garden rooms in Powys that are hard to connect to the main heating can have their own air-to-air unit. Installers in Powys plan condensate drains and pipe covers so indoor and outdoor runs stay neat. Flats in Powys on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework.
Who it suits
- Rooms that get too hot in summer as well as cold in winter
- Extensions, conservatories and garden rooms
- Flats and apartments with storage or panel heaters
- Households that already have, or will add, a separate source of hot water
Grants and rules for heat pumps in Wales
Homes in Powys can use the Boiler Upgrade Scheme, which applies in Wales as well as England: £7,500 towards an air source heat pump, or £9,000 when it replaces oil or LPG heating for installations from 21 July 2026 to 31 March 2027. The MCS-certified installer named in your quote applies and deducts the grant.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Wales has its own permitted development rules for air source heat pumps, so we check what applies to your property, including listed building and conservation-area constraints, at the 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.
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.
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.
