Air-to-air heat pumps for Merthyr Tydfil homes
Every property in Merthyr Tydfil is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
A survey in Merthyr Tydfil covers indoor unit positions, pipe routes and hot water for homes across Mid Glamorgan. Extensions and garden rooms in Merthyr Tydfil 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.
- Households that already have, or will add, a separate source of 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
What's included
- Free survey covering rooms to heat, unit positions and hot water options
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Condensate drains and neat external pipe covers
- Electrical supply and controls set up for each room
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
For terraced homes in Merthyr Tydfil, the outdoor unit can often sit in a rear yard with tidy pipe runs to each room.
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 Merthyr Tydfil quote.
There is no VAT on installing a heat pump anywhere in the UK, Wales included, until 31 March 2027. Planning rules for heat pumps in Wales are set by the Welsh Government and differ from England's, so the surveyor checks the unit position against them.

| Air-to-air heat pump, multi-room 3–4 bedroom home | £4,000–£8,000 |

Air-to-air heat pumps in Merthyr Tydfil: questions
How soon can you survey a home in Merthyr Tydfil?
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.
Can you service a heat pump in Merthyr Tydfil that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Merthyr Tydfil, whoever fitted them. Tell us the make and model when you book.
What size heat pump does a Merthyr Tydfil 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 Merthyr Tydfil home.
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 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.
