A Guide to Heat Pump Installation Costs for Irish Homeowners

As energy costs rise and environmental concerns grow, many Irish homeowners are exploring heat pumps as a sustainable alternative to traditional heating systems.

With insights from John Valentine of Crystal Air Renewable Energy, this guide walks you through the costs, process and benefits of installing a heat pump in your home.

What Is the Average Cost of Installing a Heat Pump?

The cost of installing a heat pump varies depending on home size, the system type, and the extent of preparatory work required. For a typical home of around 100m², a 5kW air source heat pump might cost between €10,000 and €15,000. However, the SEAI grant of €6,500 can significantly offset this cost.

Factors Influencing Installation Costs

Several variables can impact the cost of installing a heat pump:

Home Size and Insulation: Larger homes require more powerful heat pumps. Homes with a Heat Loss Indicator (HLI) above 2 may need additional insulation, such as cavity wall or attic upgrades, to qualify for grants.
Radiator and Cylinder Changes: Lower operating temperatures of heat pumps often necessitate radiator upgrades or the replacement of old hot water cylinders.
System Type: While air-source heat pumps are generally more affordable, ground-source systems, which require extensive groundwork, are costlier.
Existing Heating System: The removal of old systems, such as boilers or oil tanks, is typically included in the installation quote but may incur additional charges for steel tank disposal.

Process for Installing a Heat Pump in Ireland

The installation process is straightforward, especially when grant aid is involved:

Technical Assessment: A heat loss assessment determines the home's HLI. This costs approximately €600, with a €200 grant available if a heat pump is installed. Homes built after 2007 are usually exempt.
Installation: This includes power flushing radiators, installing the heat pump and associated components, and commissioning the system. Typical installations are completed within a working week.
Post-Works BER: A final Building Energy Rating (BER) assessment (approximately €200) is required to claim the grant.

Maintenance and Running Costs

Heat pumps are highly efficient, but annual maintenance is essential for optimal performance and to uphold warranties. Maintenance typically costs around €200 plus VAT.

Running costs are lower than traditional systems, with potential energy savings of up to 70%. However, the primary benefit, as highlighted by homeowners, is the consistent comfort and reduced reliance on fossil fuels.

Pro Tip: To save on running costs, keep your heat pump on 24/7. Letting the system maintain a steady temperature is far more efficient than reheating a cold home!

Key Benefits and Tips for Cost Savings

Environmental Impact: Heat pumps significantly reduce CO2 emissions and fossil fuel consumption.
Grant Support: The SEAI offers a grant of €6,500 for heat pump installations, making them more affordable for homeowners.
Optimising Efficiency: Run your heat pump continuously to maintain steady indoor temperatures, avoiding the inefficiency of reheating a cold home.

Why Choose Air Source Over Ground Source Heat Pumps?

While ground-source heat pumps are slightly more efficient, the upfront cost is higher due to the extensive groundwork required. Modern air source heat pumps deliver comparable efficiency at a significantly lower cost, making them the preferred choice for most retrofits.

Common Challenges to Anticipate

Radiator Adjustments: The lower water temperatures require larger radiators in some cases.
Cylinder Compatibility: Most homes need a new integrated heat pump cylinder for efficient hot water storage.
Insulation Requirements: Older homes may need upgrades to meet grant criteria.
