What to know about air-to-air heat pumps in Mountain Ash
Most homes can run on a heat pump if the system is designed properly, and Mountain Ash is no different. The key is matching the heat pump and radiators to the home's heat loss.
Flats in Mountain Ash on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework. Top-floor rooms in Mountain Ash that overheat in summer gain from the cooling an air-to-air system provides.
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.
- Homes where fitting radiators and pipework would be very disruptive
- Rooms that get too hot in summer as well as cold in winter
- 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
- 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
- Outdoor unit and indoor units for each room
A survey in Mountain Ash covers indoor unit positions, pipe routes and hot water for homes across Mid Glamorgan.
Grants and rules for heat pumps in Wales
In Wales the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027; £2,500 for air-to-air). The MCS-certified installer named in your quote applies to Ofgem for you, and the grant comes off your Mountain Ash quote.
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 Mountain Ash
The ranges below are typical installed prices for homes in Mid Glamorgan, including VAT. A survey sets the exact figure, because two similar-looking houses in Mountain Ash 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.
Short winter days in Mountain Ash and what they mean
On the shortest day Mountain Ash gets about 7 hours 48 minutes of daylight, with the noon sun around 15° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

Air-to-air heat pumps in Mountain Ash: questions
How long does a heat pump survey take in Mountain Ash?
A home survey in Mountain Ash usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
How soon can you survey a home in Mountain Ash?
Survey dates depend on how busy installers are in Mid Glamorgan. We offer the next available dates when you enquire and confirm them in writing.
Do you cover Aberdare as well as Mountain Ash?
Yes. We arrange surveys and installation in Aberdare, which is about 4 miles north-west of Mountain Ash, and across Mid Glamorgan.
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.
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.
