Air source heat pump installation for Donaghadee homes
Every property in Donaghadee 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.
Installers working in Donaghadee plan the order of work so heating and hot water are off for as short a time as practical. Terraced streets in Donaghadee often mean a compact unit position at the rear, so siting and sound levels are checked carefully.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Households with room for a hot water cylinder
- Homes replacing a gas, oil, LPG or electric heating system
- Owners who want one contract covering design, fitting and paperwork
What's included
- Radiator and pipework changes where the design needs them
- System design, unit sizing and a written quote
- Free home survey and room-by-room heat loss calculation
- Outdoor unit, hot water cylinder and weather compensation controls
- MCS registration and certificate, plus network operator notification
In Donaghadee, cylinder space is planned with you, often in an airing cupboard, utility room or garage.
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 Donaghadee.
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.

Short winter days in Donaghadee and what they mean
On the shortest day Donaghadee gets only about 7 hours 14 minutes of daylight and the noon sun sits around 12° 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.

Air source heat pump installation in Donaghadee: questions
Do I need new radiators for a heat pump in Donaghadee?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Donaghadee home gives a room-by-room list.
What size heat pump does a Donaghadee 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 Donaghadee home.
How long does a heat pump survey take in Donaghadee?
A home survey in Donaghadee usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
What grants can I get for a heat pump?
It depends on where you live. In England and Wales the Boiler Upgrade Scheme gives £7,500 towards an air-to-water heat pump, which the installer claims and deducts from your quote. In Scotland, Home Energy Scotland offers a grant of up to £7,500, with up to £1,500 more for eligible rural and island homes, but you need a written funding offer before work starts. Northern Ireland has no dedicated homeowner heat pump grant at present.
