When you’re planning and building your own home, every decision matters. From the insulation levels you choose to the heating system that will keep your house warm for decades to come.
For many self-builders in Ireland, choosing the right heating system is one of the most important long-term decisions in the entire project. A well-designed heat pump system can help improve comfort, lower running costs, support a better BER rating and future-proof your home for years to come.
Heat pumps are now a go-to option for new builds, but understanding which type of system is best suited to your property is the main question. This guide looks at key considerations self-builders should consider when choosing a heat pump system for their home.
Air Source Heat Pumps Vs Ground Source Heat Pumps – Which is better for a Self-Build?
Both air-source and ground-source heat pumps provide renewable heating and hot water for a property. The right solution will depend on factors such as available space, installation requirements and budget.
Air source heat pumps are often the most practical option for self-build projects because they are simpler to install, require less groundwork, and suit a wide range of property types and plot sizes.
Ground source heat pumps can offer excellent long-term efficiency, however they generally require more outdoor space and higher upfront installation costs.

What should self-builders consider before choosing a heat pump?
Insulation and air tightness
Heat pumps perform best in homes with high levels of insulation and airtightness. Reducing heat loss allows the heating system to operate more efficiently while maintaining comfortable indoor temperatures throughout the home.
Heat pump sizing
Correct heat pump sizing is one of the most important parts of the heating system design process. A professional heat loss calculation should always be carried out to determine the heating requirements of the property.
An incorrectly sized heat pump can affect both comfort levels and system efficiency, making professional system design essential.
Planning the heating system early
Heating design should ideally be considered early in a self-build project. Decisions around insulation, heat emitters, hot water storage, and room layouts can all influence the overall efficiency and performance of the heating system.
Heat emitters
Heat pumps work particularly well with low-temperature heat emitters such as underfloor heating and correctly sized radiators.
Many self-build homes choose underfloor heating for ground floor areas because it distributes heat evenly across large spaces and works efficiently at lower flow temperatures. However, modern aluminium radiators can also provide an effective solution when correctly specified.
Why many self-builders choose the Grant Aerona R290
The Grant Aerona R290 air source heat pump range has been designed to deliver efficient low-carbon heating for modern homes. With A+++ energy ratings, natural R290 refrigerant, low sound levels, and compatibility with smart controls, the Aerona R290 is designed to perform efficiently in Irish weather conditions while helping homeowners improve comfort and energy efficiency. Available in outputs ranging from 4kW to 16kW, the Aerona R290 range can suit a variety of self-build property types and heating requirements.
Choosing the right heat pump for a self-build home is about balancing comfort, efficiency, running costs and future-proofing.
By considering the heating demands of the property and ensuring the system is correctly designed and sized, self-builders can create an efficient and comfortable home for the future.
