As more homeowners in Ireland look to sustainable energy solutions, heat pumps are the preferred option for heating homes. A heat pump can provide efficient and environmentally friendly heating, but before you make the switch, it’s important to assess whether your home is “heat-pump ready”.
1. Understanding Heat Pumps
A heat pump is a device that extracts heat from the air, ground, or water outside your home and transfers it inside to provide heating. Unlike traditional boilers, which burn fuel to generate heat, heat pumps move existing heat, making them highly efficient. This efficiency translates into lower energy bills and a reduced carbon footprint.
2. Insulation: The Foundation of Heat-Pump Readiness
One of the most critical factors in determining whether your home is ready for a heat pump is its level of insulation.
Wall Insulation: Homes with solid walls should have external or internal insulation installed. Cavity walls should be properly insulated to minimise heat loss.
Roof Insulation: Ensure your attic or roof is insulated to the recommended levels. SEAI suggests at least 300mm of insulation for optimal performance.
Floor Insulation: Insulating floors can further reduce heat loss and improve the heat pump’s efficiency.
Without adequate insulation, a heat pump may struggle to maintain a comfortable temperature, leading to higher running costs and less effective heating.
3. Window and Door Upgrades
Heat pumps work best in homes that are airtight. Draughty windows and doors can significantly undermine a heat pump’s efficiency. The SEAI advises upgrading to double or triple-glazed windows and ensuring that doors are properly sealed. This reduces heat loss and prevents cold air from entering, making your home more heat-pump friendly.
4. Heating System Compatibility
Another key consideration is the compatibility of your current heating system. Heat pumps work most efficiently with low-temperature heating systems such as underfloor heating or larger radiators designed for lower flow temperatures.
Underfloor Heating: If your home already has underfloor heating, it’s likely well-suited to a heat pump. This type of heating works well with the lower temperatures that heat pumps provide.
Radiators: Homes with radiators should be assessed to ensure that they are adequately sized. Larger radiators may be needed to compensate for the lower water temperatures provided by a heat pump.
5. Sizing and Location of the Heat Pump
The size of the heat pump is crucial for its performance and efficiency. An undersized pump will struggle to heat your home adequately, while an oversized pump can lead to inefficiency and higher operational costs. Our Retrofit Project Coordinators will advise the correct size based on your home’s specific requirements.
6. Grants
In Ireland, we benefit from generous grants through the SEAI for installing heat pumps which help offset the cost of installation. An second tier of grants are available through the Community Energy Grant scheme for additional measures such as airtightness, windows and doors to make your home more heat-pump ready. These grants aren’t available as individual measures through the Home Energy Grants scheme.
7. Technical Assessment
Finally, a technical assessment of your home must be conducted before installing a heat pump through the Community Energy Grant scheme. A qualified technical assessor can evaluate your home’s insulation, heating system, and other factors to determine the best approach for increasing the efficiency of your home, while ensuring best value for your money.
Transitioning to a heat pump is a significant step toward reducing your home’s carbon footprint and improving energy efficiency. However, ensuring that your home is heat-pump ready is essential for maximising the benefits.
