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 West Glamorgan that overheat in summer gain from the cooling an air-to-air system provides. A survey in West Glamorgan covers indoor unit positions, pipe routes and hot water for homes across West Glamorgan. Extensions and garden rooms in West Glamorgan 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
- Homes where fitting radiators and pipework would be very disruptive
- Extensions, conservatories and garden rooms
- Rooms that get too hot in summer as well as cold in winter
Grants and rules for heat pumps in Wales
Homes in West Glamorgan 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.

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.
How much sound do the indoor units make?
Indoor units are designed to run quietly, with a fan you will hear most when heating or cooling at full output. Lower fan settings and night modes reduce sound in bedrooms. Siting matters for the outdoor unit too: it needs airflow and a position that passes the MCS noise assessment. Ask to see the sound levels of the proposed units at survey.
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.
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.
