Air-to-air heat pumps for Renfrew homes
In Renfrew, 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.
Extensions and garden rooms in Renfrew that are hard to connect to the main heating can have their own air-to-air unit. Top-floor rooms in Renfrew 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.
- Households that already have, or will add, a separate source of hot water
- Homes where fitting radiators and pipework would be very disruptive
- Extensions, conservatories and garden rooms
What's included
- Electrical supply and controls set up for each room
- Free survey covering rooms to heat, unit positions and hot water options
- Condensate drains and neat external pipe covers
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Outdoor unit and indoor units for each room
Installers in Renfrew plan condensate drains and pipe covers so indoor and outdoor runs stay neat.
Grants and rules for heat pumps in Scotland
In Scotland, heat pump funding comes through Home Energy Scotland rather than the Boiler Upgrade Scheme: a grant of up to £7,500 (up to £1,500 extra for eligible rural and island homes) and an optional interest-free loan of up to £7,500. For a Renfrew home, apply and receive the written offer before the installation date is fixed.
There is no VAT on installing a heat pump anywhere in the UK, Scotland included, until 31 March 2027. Scottish permitted development rules and building standards apply, and the surveyor checks the unit position and any listed or conservation-area constraints.
Air-to-air heat pumps prices in Renfrew
These are guide prices for Renfrewshire and Inverclyde, 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.
Short winter days in Renfrew and what they mean
On the shortest day Renfrew gets only about 6 hours 58 minutes of daylight, with the sun around 11° up at noon. Long Scottish winters mean the heat pump runs for much of the year, so careful sizing, good controls and correctly sized radiators make a real difference.
How installation works in Renfrew
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Renfrew; the surveyor measures rooms, windows and radiators and looks at cylinder space.
- The design and quote arrive in writing, including radiator changes and the outdoor unit position.
- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Air-to-air heat pumps in Renfrew: questions
Can you service a heat pump in Renfrew that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Renfrew, whoever fitted them. Tell us the make and model when you book.
Where would the outdoor unit go on a Renfrew 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 Renfrew home.
What size heat pump does a Renfrew 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 Renfrew home.
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.
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.
