What is Heat Pump?
A device that extracts heat from the air or ground to heat your home, often paired with solar panels for maximum savings.
Quick Answer
Heat pumps are heavily promoted by the SEAI as part of Ireland's decarbonisation strategy. SEAI grants of up to €6,500 (air source) or €12,500 (ground source) are available. Combining solar PV with a heat pump is increasingly common in Ireland — the solar panels generate the electricity the heat pump needs, reducing running costs to near zero. This combination is standard in new NZEB homes.

Heat Pump Explained
A heat pump is a heating system that extracts warmth from the outside air (air source) or ground (ground source) and transfers it to your home. Heat pumps are highly efficient — they typically produce 3–4 kWh of heat for every 1 kWh of electricity consumed (a COP of 3–4). They can provide both space heating and hot water. When paired with solar panels, the solar electricity can power the heat pump, creating an extremely efficient heating system.

Frequently Asked Questions
Should I get solar panels or a heat pump first?
If your home is well-insulated, either works first. Solar panels are cheaper and have faster payback. A heat pump gives bigger heating savings. Ideally, plan for both.
