Heat pumps in Mayo
Census 2022 counted 51,996 households in Mayo. 9% heat with electricity, the group heat pumps are counted in, against 12% nationally: the 17th highest of the 26 counties. 29% of Mayo homes have a renewable energy source, such as a heat pump or solar panels. Oil still heats 63% of Mayo homes, the fuel a heat pump most often replaces.
7% of Mayo homes were built since 2011, and 498 new homes were finished in 2025, with 390 more from January to September 2026. New homes have to meet Part L's renewable energy rules, which is why so many have a heat pump and mechanical ventilation. Their first warranties end within a few years, and that's when yearly servicing pays for itself.
The Mayo climate
Castlebar gets 2,028 heating degree days a year, the 13th highest of the 26 counties' main towns. That's milder than much of the midlands and the north-west, so heat pumps in Mayo work less hard, but damp air still means regular defrosts in winter.
Near the Mayo coast, salt air builds up on outdoor coils and fins. A coastal service costs €180 to €240, and the unit should sit out of the direct sea wind.
