The climate for heat pumps in Llucmajor
Llucmajor lies at about 146 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 11.6 °C, and the municipality has about 339 heating degree days a year, 14% more than Palma (297). For comparison, Palma has 297 and Campos 320.
In this climate, for a 120 m² home built between 1980 and 2006 we estimate a heating demand of about 6,164 kWh a year and about 7.5 kW of power, covered by a 8 kW Vaillant aroTHERM plus.
Compared with an oil boiler (about €1,653 a year for heating and hot water for 3 people), a heat pump with radiators would cost about €514: indicative savings of €1,139 a year. Underfloor heating or fan coils improve efficiency further.
Heat pump grants in Llucmajor
If the heat pump replaces an oil, propane or gas boiler, a Vaillant unit earns about €2,000 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 8 kW unit would have received up to €5,600 (€700 per kW of heating output). If you already applied, we help you with the final paperwork.
What to consider in Llucmajor
On rural properties we often replace oil or propane boilers; a heat pump removes the fuel tank and deliveries.
Near the sea we protect the outdoor unit against salt air and position it to reduce noise.
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 Llucmajor: large houses and pools
Homes in the Llucmajor developments tend to be large and single-storey, which suits underfloor heating and cooling very well. Where there is a pool, we heat it with the same unit. In the old town, with sandstone walls and high ceilings, we size the system with a little more margin.
