Heat pumps are becoming an increasingly popular heating solution in Ireland due to their energy efficiency, eco-friendliness, and potential cost savings. As the country moves toward more sustainable energy solutions, homeowners are turning to heat pumps as a long-term investment.

However, the question remains – how much does heat pumps cost in Ireland? The total cost depends on various factors, including the type of heat pump, the size of your home, and installation complexity.

In this guide, we’ll explore heat pump types, costs, potential savings, and available grants.

How Much Does Heat Pumps Cost in Ireland?

The exact cost of a heat pump installation can vary based on several factors, including the type of heat pump, the size of your home, and its compatibility with your existing heating system.

For an average 3-bedroom home in Ireland, the estimated costs are as follows:

  • Air Source Heat Pump: €12,000 – €18,000
  • Ground or Water Source Heat Pump: €17,000 – €28,000

These costs include the purchase of the heat pump and installation but may vary depending on specific site conditions and the installer’s rates.

Types of Heat Pumps and How Much Do They Cost?

The cost of heat pumps in Ireland varies depending on the type of system. Below is a breakdown of the most common types:

1. Air Source Heat Pumps

  • Cost: €12,000 – €18,000
  • How It Works: Transfers heat from the air outside your home into your heating system. There are two types:
    • Air-to-Water Heat Pumps: Heats both air and water, making it suitable for radiators and underfloor heating.
    • Air-to-Air Heat Pumps: Only heats air, primarily for space heating.
  • Pros: Easier and less costly to install compared to other types.
  • Cons: Less efficient during colder weather and cannot heat water if using air-to-air systems.

2. Ground Source Heat Pumps

  • Cost: €17,000 – €28,000
  • How It Works: Extracts heat from the ground using buried pipes. Ideal for well-insulated homes with large outdoor space.
  • Pros: More efficient than air source heat pumps, especially in cold climates.
  • Cons: High upfront cost and requires significant outdoor space for installation.

3. Water Source Heat Pumps

  • Cost: €17,000 – €28,000
  • How It Works: Captures heat from open water sources like lakes or rivers. The heated water is used in radiators, underfloor heating, or hot water systems.
  • Pros: Highly efficient, especially in colder weather.
  • Cons: Installation depends on proximity to a water body, making it less feasible for many homeowners.

What Factors Affect Heat Pump Costs in Ireland?

Several factors influence the total cost of installing a heat pump:

1. Type of Heat Pump

As outlined above, air source heat pumps are generally cheaper to install than ground or water source systems.

2. Size of the Heat Pump

The size of your home and its heating needs will determine the size of the heat pump required. A larger system will cost more but will also provide adequate heating for a bigger space.

3. Installation Complexity

Ground and water source heat pumps involve more complex installations, requiring excavation and pipework, leading to higher costs compared to air source systems.

4. Home Insulation

Well-insulated homes require less energy to heat, meaning a smaller and less expensive heat pump can be installed. An SEAI assessment ensures that homes meet insulation standards before installation.

What Grants Are Available for Heat Pump Installation in Ireland?

The Sustainable Energy Authority of Ireland (SEAI) offers grants to help reduce the cost of heat pump installation.

  • Grant Amount: Up to €6,500 for homes built before 2021.
  • Assessment Grant: €200 to cover the cost of a home assessment by an SEAI registered technical advisor.
  • Eligibility Criteria:
    • The home must have adequate insulation to retain heat.
    • A technical assessment must be completed before applying for the grant.

For air-to-air heat pumps, grants of up to €3,500 are available, but they are typically smaller as they do not provide hot water.

How Much Can You Save by Using a Heat Pump?

Although the upfront cost of installing a heat pump may seem high, it offers long-term financial benefits in the form of reduced energy bills.

1. Lower Energy Costs

  • Air Source Heat Pumps: Up to 50% reduction in energy bills a year.
  • Ground and Water Source Heat Pumps: Up to 75% reduction.

2. Annual Running Costs

  • €600 to €1,000 per year, depending on the type of heat pump and household energy consumption.
  • Elimination of gas or oil costs, with only electricity required for operation.

Which Heat Pump is Best for Your Home?

Choosing the right heat pump depends on several factors, including:

  • Your Location: Water source heat pumps require proximity to a large body of water.
  • Climate: Ground and water source pumps are more efficient in colder climates, whereas air source heat pumps perform better in milder conditions.
  • Property Size: Ground source heat pumps need enough outdoor space for pipework, while split systems require more indoor space than monobloc systems.
  • Budget: While ground and water source heat pumps are more expensive upfront, they offer greater efficiency and long-term savings.

Conclusion

Heat pumps are a sustainable and cost-effective heating solution for Irish homes, offering significant long-term savings. Depending on the type, installation costs range from €12,000 to €28,000, but SEAI grants can help reduce the upfront expense. Whether you're considering an air, ground, or water source heat pump, choosing the right system depends on your home's size, location, and budget.

How to clone into other project?

  • Press "Ctrl + E" or "Cmd + E" in the Designer and enable "Select on-page element".

  • Search for the class named, "Cloneable Area".

  • Copy the element inside this container to your own project.

  • Rename the classes accordingly if they are clashing with your project.

  • Ensure custom code from the in-page setting has been copied into your project as well (if there's any).

  • 'Page Trigger' interaction can't be copied directly. You can only clone the whole project, or rebuild it.
    A simple trick to copy the 'Page Trigger' interaction into another project is as below:

    1. Create a dummy element.
    2. Apply any type of 'Element trigger' into the dummy element and select the 'Page Trigger' animation.
    3. Copy the dummy element with the animations applied into your new project.
    4. The animation should have been copied into your project and you can reapply the 'Page Trigger' animation into your project.

  • If you have further inquiry or need assistance, feel free to contact us.

  • Lastly, please do not copy this project and claim it as your own. We wish to continue sharing and giving to the community. In order to do so, we will need your cooperation and full support. Thank you very much,
