The climate for heat pumps in Sóller
Sóller lies at about 45 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 January, averaging 10.2 °C, and the municipality has about 530 heating degree days a year, 78% more than Palma (297). For comparison, Bunyola has 371 and Valldemossa 482.
In this climate, for a 120 m² home built between 1980 and 2006 we estimate a heating demand of about 9,450 kWh a year and about 9.5 kW of power, covered by a 10 kW Vaillant aroTHERM plus.
Compared with an oil boiler (about €2,310 a year for heating and hot water for 3 people), a heat pump with radiators would cost about €713: indicative savings of €1,597 a year. Underfloor heating or fan coils improve efficiency further.
Heat pump grants in Sóller
If the heat pump replaces an oil, propane or gas boiler, a Vaillant unit earns about €2,500 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 10 kW unit would have received up to €7,000 (€700 per kW of heating output). If you already applied, we help you with the final paperwork.
What to consider in Sóller
Winters in the Serra de Tramuntana are colder and damper than on the coast, so we size the heat pump with a margin and position the outdoor unit to fit the protected landscape.
For holiday homes, app control lets you switch on heating or cooling before you arrive.
Complete, certified installation
We calculate heat loads, choose the emitters, install the unit and hot-water tank, certify it under RITE and handle the CAE and the energy certificates for the income-tax deduction.

Heat pumps in Sóller: the coldest part of the island
In the Sóller valley and the Serra temperatures drop further than on the coast, so we size the heat pump with margin and pay particular attention to pipe insulation. The stone houses, with their thermal mass, work very well with underfloor heating running continuously.
