Replacing electric heating with a heat pump means taking out storage heaters, panel heaters or an electric boiler and installing an air-to-water heat pump that heats water for radiators or underfloor heating and a hot water cylinder. If you already have an electric boiler and radiators, the change is similar to a boiler swap. If you have storage or panel heaters, there is no wet system yet, so radiators and pipework need to be installed throughout.
Installers in County Armagh work room by room, so you can stay in your home while radiators go in. For County Armagh homes with solid floors, the survey plans pipe routes through walls and ceilings to keep disruption predictable. Owners across County Armagh moving off storage heaters can arrange a survey in County Armagh that compares running costs on their real tariff.
Who it suits
- Owners planning redecoration or other building work at the same time
- Bungalows and houses with suspended timber floors that make pipe runs easier
- Homes with storage heaters or panel heaters throughout
- Properties with an electric boiler and existing radiators
Grants and rules for heat pumps in Northern Ireland
The Boiler Upgrade Scheme covers England and Wales only, and there is currently no dedicated heat pump grant for homeowners in Northern Ireland. Our quote for a home in County Armagh is therefore shown without a grant deduction; if support becomes available we will tell you how it applies.
Installing heat pumps has been zero-rated for VAT in Northern Ireland since 1 May 2023, in line with the rest of the UK, until 31 March 2027. Northern Ireland has its own permitted development rules and building regulations, and we confirm what applies to your property at survey.

Replacing electric heating with a heat pump questions
Do I qualify for the Boiler Upgrade Scheme if I have electric heating?
In England and Wales, owners of existing homes replacing electric heating can qualify, provided the heat pump meets the home's full heating and hot water needs and the other scheme conditions are met. The grant is £7,500 for an air-to-water system. The scheme does not cover Scotland or Northern Ireland; Scotland has separate Home Energy Scotland funding.
How disruptive is fitting radiators in a home that has none?
More disruptive than a boiler swap, but planned. Floorboards are lifted to run pipes, some holes are drilled through walls and radiators are hung room by room. Rooms are worked on in a set order so you can keep living at home, and holes are made good, while redecoration is usually yours. The programme in your quote shows how long each stage typically takes.
Can I keep my electric immersion cylinder?
Usually not for heating by the heat pump, because a standard immersion cylinder has no coil, or one too small to take heat at low flow temperatures. A heat pump cylinder replaces it, often in the same cupboard, and keeps an immersion element as backup. If you choose an air-to-air system instead, which does not make hot water, the existing cylinder stays in use.
What if I live in a flat?
Many flats can have a heat pump, but you need a suitable outdoor position, such as a balcony, yard or wall bracket, and leaseholders need consent from the freeholder or management company. Planning permission may be needed depending on the nation and the building, which we check at survey. Where a wet system is impractical, an air-to-air heat pump with separate hot water is an alternative.
