Before you book: air-to-air heat pumps in Mumbles
Most homes can run on a heat pump if the system is designed properly, and Mumbles is no different. The key is matching the heat pump and radiators to the home's heat loss.
Installers in Mumbles plan condensate drains and pipe covers so indoor and outdoor runs stay neat. Extensions and garden rooms in Mumbles that are hard to connect to the main heating can have their own air-to-air unit.
An air-to-air heat pump warms rooms directly with air, and can cool them in summer, but it does not heat your hot water.
- Extensions, conservatories and garden rooms
- Homes where fitting radiators and pipework would be very disruptive
- Households that already have, or will add, a separate source of hot water
What's included
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
- Outdoor unit and indoor units for each room
- Free survey covering rooms to heat, unit positions and hot water options
- Condensate drains and neat external pipe covers
- Electrical supply and controls set up for each room
Top-floor rooms in Mumbles that overheat in summer gain from the cooling an air-to-air system provides.
Grants and rules for heat pumps in Wales
Homes in Mumbles 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.
What to budget for air-to-air heat pumps in Mumbles
The ranges below are typical installed prices for homes in West Glamorgan, including VAT. A survey sets the exact figure, because two similar-looking houses in Mumbles can need quite different radiators and pipework.
| System | Installed guide price |
|---|---|
| Air-to-air heat pump, 1–2 rooms | £2,400–£5,000 |
| Air-to-air heat pump, multi-room 3–4 bedroom home | £4,000–£8,000 |
Installed, inc VAT. Air-to-air systems heat (and can cool) rooms but do not provide hot water. In England and Wales the Boiler Upgrade Scheme gives £2,500 towards an air-to-air system in a home, deducted from your quote where eligible.
Designing for Mumbles's winters
Mumbles sees roughly 7 hours 49 minutes of daylight in late December against 16 hours 39 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.

- We commission the heat pump, show you the controls and register the installation.
Air-to-air heat pumps in Mumbles: questions
What size heat pump does a Mumbles home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Mumbles home.
Where would the outdoor unit go on a Mumbles house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Mumbles home.
How long does installation take in Mumbles?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Mumbles home states the expected time.
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.
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.
