Heat pumps are quickly becoming the preferred heating solution for Irish homes. With rising energy costs and strong government incentives, thousands of homeowners are now switching from oil or gas heating to renewable systems.
The Sustainable Energy Authority of Ireland (SEAI) offers generous grants to help homeowners install heat pumps and improve home energy efficiency.
If you’re planning to install a heat pump in Ireland, understanding the process can help you avoid delays and maximise your grant support.
This guide explains exactly how to start a heat pump installation, from choosing an installer to claiming your SEAI grant.
Step 1: Choose a SEAI-Registered Installer
The first step in installing a heat pump is selecting a qualified contractor.
Always choose an SEAI-registered heat pump to ensure the system meets Irish energy standards and qualifies for government grants.
Tips for choosing the right installer
- Contact multiple installers before making a decision
- Request detailed quotes for the full installation
- Ask for customer references or reviews
- Speak to friends or neighbours who have installed heat pumps
Comparing quotes helps you understand the true installation cost and available system options.
Step 2: Choose the Right Heat Pump System
There are several types of heat pump systems available, and choosing the right one depends on your home’s size, insulation level, and available space.
Common systems include:
Air-to-Water Heat Pumps
The most popular option in Ireland.
Benefits:
- Lower installation cost
- Works well in Irish climate
- Ideal for retrofits and urban homes
Ground-Source Heat Pumps
More efficient but higher installation cost.
Benefits:
- Very stable performance year-round
- Lower long-term running costs
- Ideal for homes with larger gardens
Your installer will assess your property and recommend the most suitable heat pump system.
Step 3: Apply for the SEAI Heat Pump Grant
Before any installation work begins, you must apply for your grant through the Sustainable Energy Authority of Ireland.
There are two main grant options available.
Individual Heat Pump Grant
This option is suitable if you only want to install a heat pump.
Best for:
- Homes that are already well insulated
- Homeowners planning a single heating upgrade
One Stop Shop Grant Programme
A One Stop Shop provider manages the entire project, including:
- Home energy upgrades
- Grant application
- Installation coordination
This option is ideal if you plan to carry out multiple upgrades such as insulation, windows, or solar panels along with the heat pump installation.
Step 4: Heat Pump System Design
Once your grant application is approved, the installer will design the heating system.
A heat pump is designed to provide:
- 100% of your home heating
- At least 80% of hot water demand
Heat Demand Calculation
Your installer will calculate the heat demand for each room in your house.
This helps determine:
- The correct heat pump size
- Radiator requirements
- System efficiency
Radiator and Underfloor Heating Assessment
Heat pumps operate at lower temperatures than traditional boilers, so your installer may recommend:
- Larger radiators
- Underfloor heating upgrades
Funding may be available through the Better Energy Homes Programme to help cover these upgrades.
Outdoor Unit Placement
If installing an air source heat pump, you’ll need space for the outdoor unit.
Placement considerations include:
- Close to the house for efficiency
- Away from bedroom windows
- Proper airflow around the unit
Your installer will advise on the best location.
Step 5: Heat Pump Installation and Commissioning
Once everything is approved and designed, installation can begin.
What to expect during installation
- Installation usually takes 2–5 days
- Heating may be unavailable temporarily
- New pipework or radiators may be installed
After installation, the system goes through commissioning.
What Is Commissioning?
Commissioning ensures your system is running efficiently.
During this process, the installer will:
- Configure system settings
- Test heating performance
- Adjust controls for maximum efficiency
They will also explain how to operate your heating system.
Important Questions to Ask Your Installer
Before they leave, make sure you ask about:
- System controls and thermostat settings
- Warranty coverage
- Maintenance schedule
- Service contracts for future support
Heat pumps require very little manual adjustment once properly set up.
Step 6: Submit Documents and Claim Your Grant
After installation, the final step is claiming your grant.
If you applied for the individual heat pump grant:
- You have 8 months to complete installation
- A post-works BER assessment must be completed
- Submit documentation to SEAI
The grant payment is then transferred directly to your bank account.
If You Used a One Stop Shop
The process is simpler.
The One Stop Shop provider:
- Handles all paperwork
- Applies for the grant on your behalf
- Deducts the grant from the project cost upfront
