Air Source Heat Pump Installation BELFAST & LISBURN
Thinking about switching to a heat pump?
You’re not alone. More homeowners across Belfast, Lisburn and Newtownards are exploring air source heat pumps as a way to reduce energy bills, lower their carbon footprint and future-proof their homes against rising fuel costs.
But heat pumps aren’t the right solution for every home — and we’ll always tell you that honestly. At Kelly Heating NI, we assess your property properly before we recommend anything. If a heat pump is right for you, we’ll install it to the highest standard. If it isn’t, we’ll tell you that too and point you toward what will work best.
That’s how we do things.
What Is an Air Source Heat Pump?
An air source heat pump is a heating system that extracts warmth from the outside air – even in cold temperatures – and uses it to heat your home and hot water. Unlike a gas or oil boiler, which burns fuel to generate heat, a heat pump moves heat that already exists in the air, making it significantly more energy efficient.
For every unit of electricity a heat pump uses, it typically produces three to four units of heat. That ratio — known as the Coefficient of Performance (CoP) — is what makes heat pumps one of the most efficient heating options available for suitable homes.
Is Your Home Suitable for a Heat Pump?
This is the most important question, and it’s one we take seriously. A heat pump that’s installed in the wrong home, or sized incorrectly, will underperform and cost more to run — which helps nobody.
A home is generally well suited to a heat pump if it:
- Is well insulated, with good loft and wall insulation
- Has double or triple glazing
- Has a reasonable EPC (Energy Performance Certificate) rating
- Has space outside for the external unit — typically on a wall or in a garden
- Has, or is willing to upgrade to, larger radiators or underfloor heating (heat pumps work best at lower flow temperatures)
Newer homes across Belfast and Newtownabbey are often well suited. Older Victorian or Edwardian properties in South Belfast or Lisburn may need insulation improvements first – and we’ll tell you this upfront, not after the installation.
If you’re unsure, the best step is simply to get in touch. We’ll give you an honest answer.
The Benefits of an Air Source Heat Pump
When the conditions are right, an air source heat pump offers significant advantages for Belfast homeowners:
Lower Running Costs: Once installed, heat pumps typically cost less to run than oil or gas boilers, particularly as electricity tariffs for heat pump users improve over time.
Reduced Carbon Footprint: Heat pumps produce no direct emissions at the point of use. Paired with a solar PV system, you can dramatically reduce your home’s overall carbon output.
Long Lifespan: A well-installed heat pump will typically last 15–20 years with minimal maintenance — longer than most boilers.
Low Maintenance: With fewer moving parts than a boiler, heat pumps require very little ongoing maintenance — an annual check is generally all that’s needed.
Works in Cold Weather: Modern air source heat pumps are designed to operate efficiently even when outdoor temperatures drop well below zero — well within the range of a Northern Ireland winter.
Can Be Paired with Solar Panels: Using electricity generated by your own solar panels to power your heat pump significantly reduces running costs further.
What About the Drawbacks?
We believe in giving you the full picture. Heat pumps are not right for every situation, and there are some things worth knowing:
Upfront Cost: The installation cost of a heat pump is higher than a traditional oil or gas boiler.
Your Home Needs to Be Well Insulated: A poorly insulated home will work against a heat pump and increase running costs. If your home needs significant insulation upgrades first, we’ll discuss this with you honestly as part of our assessment.
Larger Radiators May Be Needed: Heat pumps operate at lower flow temperatures than boilers. In some homes this means larger radiators or underfloor heating will give better results. This is something we assess before installation.
Outdoor Unit Space: The external unit needs a suitable location — this is something we check as part of every site visit.
The right way to think about these considerations is not as reasons to avoid a heat pump, but as questions to answer properly before going ahead. That’s exactly what our assessment process does.
We’ll tell you clearly whether a heat pump suits your property, what it would involve and what it’s likely to cost.
