Heat pumps in Costitx,
gentle heat for stone houses.

Your village

Costitx: thick walls and quiet streets

Costitx is one of the small villages in the centre of the island. Its traditional houses are stone-built, with thick walls; at night, the only noise in its streets is whatever a badly placed machine makes.

Stone holds the heat

A thick stone wall has a lot of thermal inertia: it is slow to warm up and slow to cool down. The house stays more stable, and the heat pump can work for many hours on end instead of delivering bursts of heat.

Noise is decided at the design stage

An outdoor unit makes little noise, but on a quiet street it can be heard. We choose a model with a low declared sound power, place it away from bedroom windows, yours and the neighbours', and mount it on anti-vibration supports. The limits come from the municipal noise bylaw and from the values to which the Balearic Noise Act 1/2007 refers (art. 16 and fourth transitional provision).

Fincas in the municipality

On the fincas there is plenty of room for the outdoor unit and, often, an oil boiler to replace. If there are or will be solar panels, the heat pump can do a good part of its work in the sunny hours.

Grants

Heat pump grants in Costitx

In Costitx, as in the whole of Mallorca, a private individual's heat pump has the Govern's FACTOR 2026 grant: 70 % of the eligible cost. That cost is limited to €1,000/kWt of heating output (and to an additional €450/kWt for new distribution), and the grant to €25,000 per installation (BOIB no. 83, 2 July 2026). Open until 28 February 2027, while there is budget.

It can be applied for by anyone with a home address in the Balearic Islands, for units with an SPF above 2.5. Air-to-air units in homes do not qualify.

The Costitx tax bylaws we have reviewed provide no rebates for heat pumps.

If the energy certificates from before and after show the improvement the law requires, in your main home or in one you let, the income tax (IRPF) deduction for energy-efficiency works may apply (additional provision 50 of the Income Tax Act 35/2006; works until 31 December 2026). You claim the income tax (IRPF) deduction yourself in your Spanish tax return, with the invoices and certificates we give you.

We prepare the paperwork and, with your authorisation, submit the grant application and its justification; you sign the application and the grant is paid into your bank account. Whether it is awarded is up to the authorities.
