The climate for heat pumps in Calvià
Calvià lies at about 118 m above sea level, in climate zone B3 of the Spanish Building Code (CTE). According to the 2014–2023 PVGIS series (European Commission), the coldest month is February, averaging 12.9 °C, and the municipality has about 203 heating degree days a year, 32% less than Palma (297). For comparison, Palma has 297 and Bunyola 371.
In this climate, for a 120 m² home built between 1980 and 2006 we estimate a heating demand of about 4,050 kWh a year and about 6.2 kW of power, covered by a 7 kW Vaillant aroTHERM plus.
Compared with an oil boiler (about €1,230 a year for heating and hot water for 3 people), a heat pump with radiators would cost about €385: indicative savings of €845 a year. Underfloor heating or fan coils improve efficiency further.
Heat pump grants in Calvià
If the heat pump replaces an oil, propane or gas boiler, a Vaillant unit earns about €1,750 in Energy Saving Certificates (CAE). For a main home, Spanish taxpayers can also deduct 40% of the investment from income tax, up to €3,000. And the installation can be financed interest-free.

The Balearic Government’s FACTOR 2026 programme closed to applications on 17 October 2026 because its budget ran out. For reference, a 7 kW unit would have received up to €4,900 (€700 per kW of heating output). If you already applied, we help you with the final paperwork.

Heat pumps in Calvià: pools and seasonal use
Many homes in Calvià are only used part of the year, so we set the system up for remote control: the house is ready when you arrive and uses little while it is empty. In villas with a pool we heat the water with the same heat pump, using the midday solar surplus.
