Air-to-air heat pumps for Haverfordwest homes
In Haverfordwest, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
Top-floor rooms in Haverfordwest that overheat in summer gain from the cooling an air-to-air system provides. A survey in Haverfordwest covers indoor unit positions, pipe routes and hot water for homes across Dyfed.
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
- Flats and apartments with storage or panel heaters
What's included
- 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
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
- Outdoor unit and indoor units for each room
- Electrical supply and controls set up for each room
Installers in Haverfordwest plan condensate drains and pipe covers so indoor and outdoor runs stay neat.
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 Haverfordwest 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 Haverfordwest
These are guide prices for Dyfed, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.
| 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.
Winter daylight and heating in Haverfordwest

Air-to-air heat pumps in Haverfordwest: questions
Can you service a heat pump in Haverfordwest that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Haverfordwest, whoever fitted them. Tell us the make and model when you book.
Do you cover Milford Haven as well as Haverfordwest?
Yes. We arrange surveys and installation in Milford Haven, which is about 7 miles south-west of Haverfordwest, and across Dyfed.
Where would the outdoor unit go on a Haverfordwest 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 Haverfordwest home.
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 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.
