Heat Pump
Are Heat Pumps Suitable for Older Homes in Ireland?
Many older homes in Ireland can be suitable for heat pumps — but only when the home is properly assessed and prepared. This blog explains how heat pumps work in older properties, what upgrades may be needed first, and how Churchfield Home Services uses a Home Energy Assessment to confirm suitability before any installation.

The Short Answer: Yes — But Not Automatically
One of the most common questions we hear at Churchfield Home Services is whether heat pumps work in older Irish homes. The honest answer is yes, many older homes can be suitable, but not without proper planning.
Older homes behave very differently to modern builds. That’s why suitability is never assumed — it’s confirmed through assessment.
What Makes Older Homes Different
Older Irish homes, particularly those built before modern building regulations, often have:
- Solid block or stone walls
- Lower levels of insulation
- Higher heat loss
- Older radiators or heating layouts
These factors don’t rule out a heat pump, but they do affect how the system needs to be designed and what supporting upgrades may be required.

Why Insulation Comes First
Heat pumps work best in homes that can hold onto heat.
In older homes, this usually means upgrading insulation before or alongside the heat pump. This may include attic insulation, wall insulation, or other fabric improvements. At Churchfield Home Services, we focus on getting the home ready first so the heat pump can run efficiently and comfortably.
Installing a heat pump without addressing heat loss can lead to poor performance — which is exactly what the assessment step is designed to prevent.
Do Heat Pumps Work with Older Radiators?
In many cases, yes — but not always without changes.
Older homes may have smaller or fewer radiators designed for high-temperature oil or gas boilers. Heat pumps deliver steady, lower-temperature heat, so radiators may need to be upgraded or resized in some homes.
This is assessed during the Home Energy Assessment so expectations are clear before any decisions are made.
How the Home Energy Assessment Confirms Suitability
A Home Energy Assessment is the key step in determining whether a heat pump is suitable for an older home.
Through Churchfield Home Services, the assessment looks at:
- Heat loss through walls, roof, and floors
- Existing insulation levels
- Radiator and heating system layout
- Ventilation and air quality
This allows us to confirm whether a heat pump will work well in your home and what upgrades, if any, are needed to support it.
Grants and Older Homes
Heat pumps for older homes are supported by the Sustainable Energy Authority of Ireland (SEAI) through the One Stop Shop Home Energy Upgrade pathway.
When a heat pump forms part of a qualifying upgrade, grant support of up to €12,500 may be available. As a Registered SEAI One Stop Shop, Churchfield Home Services manages the full process, including assessment, planning, grant application, and installation.
Grants are approved in advance and deducted upfront, so there are no surprises later.
When a Heat Pump May Not Be the Right Choice
In some older homes, a heat pump may not be the best immediate option — particularly if major fabric upgrades are not feasible or planned.
That’s why we always say: the goal is not to install a heat pump at all costs, but to recommend what genuinely suits your home and your long-term plans.
What Happens Next?
If you live in an older home and are considering a heat pump, the first step is a Home Energy Assessment.
With Churchfield Home Services, this gives you clear, honest guidance on suitability, required upgrades, and grant support. From there, you decide if and when you want to proceed. There is no obligation to upgrade.
