Air-to-air heat pumps in Coleraine: what to expect
A heat pump suits most Coleraine homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
For terraced homes in Coleraine, the outdoor unit can often sit in a rear yard with tidy pipe runs to each room. Extensions and garden rooms in Coleraine 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.
- Rooms that get too hot in summer as well as cold in winter
- Extensions, conservatories and garden rooms
- Homes where fitting radiators and pipework would be very disruptive
What's included
- Free survey covering rooms to heat, unit positions and hot water options
- Electrical supply and controls set up for each room
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Condensate drains and neat external pipe covers
- Outdoor unit and indoor units for each room
Top-floor rooms in Coleraine that overheat in summer gain from the cooling an air-to-air system provides.
Grants and rules for heat pumps in Northern Ireland
Northern Ireland does not have a dedicated heat pump grant for homeowners at present, and the Boiler Upgrade Scheme does not apply here. Heat pumps have sometimes been funded through the Northern Ireland Sustainable Energy Programme, so it is worth checking what is open when you enquire about a home in Coleraine.
There is no VAT on installing a heat pump in Northern Ireland until 31 March 2027, the same as in Great Britain. Planning and building control here follow Northern Ireland's own rules, so the survey checks the unit position against them.
Guide prices for air-to-air heat pumps in Coleraine
These are guide prices for County Londonderry, 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 | £2,350–£4,850 |
| Air-to-air heat pump, multi-room 3–4 bedroom home | £3,900–£7,750 |
Installed, inc VAT. Air-to-air systems heat (and can cool) rooms but do not provide hot water.
How long is the heating season in Coleraine?
On the shortest day Coleraine gets only about 7 hours 08 minutes of daylight and the noon sun sits around 11° above the horizon. Northern winters tend to be longer, so a well-designed, efficient system matters more here because it runs for more of the year.
How installation works in Coleraine
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Coleraine; 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 Coleraine: questions
How long does installation take in Coleraine?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Coleraine home states the expected time.
How soon can you survey a home in Coleraine?
Survey dates depend on how busy installers are in County Londonderry. We offer the next available dates when you enquire and confirm them in writing.
What size heat pump does a Coleraine 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 Coleraine home.
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.
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.
