Air-to-air heat pumps for Porthmadog homes
The question for a Porthmadog home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
Top-floor rooms in Porthmadog that overheat in summer gain from the cooling an air-to-air system provides. For terraced homes in Porthmadog, the outdoor unit can often sit in a rear yard with tidy pipe runs to each room.
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
- Flats and apartments with storage or panel heaters
- Homes where fitting radiators and pipework would be very disruptive
What's included
- Outdoor unit and indoor units for each room
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
- Condensate drains and neat external pipe covers
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Free survey covering rooms to heat, unit positions and hot water options
A survey in Porthmadog covers indoor unit positions, pipe routes and hot water for homes across Gwynedd.
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 Porthmadog 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.

Air-to-air heat pumps in Porthmadog: questions
How soon can you survey a home in Porthmadog?
Survey dates depend on how busy installers are in Gwynedd. We offer the next available dates when you enquire and confirm them in writing.
What size heat pump does a Porthmadog 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 Porthmadog home.
How long does installation take in Porthmadog?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Porthmadog 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.
