It begins with calculating the heating and cooling loads of the home, sizing the equipment according to actual needs, choosing between radiators only, underfloor heating only, or a combination, planning space for the domestic hot water tank and outdoor unit, and providing a fixed quote.

We diagnose circuits with a thermal camera, detect leaks without breaking the floor when possible, and repair the manifold or valves as needed. The Mediterranean climate of the Costa Blanca is perfect for a modern heat pump. Mild winters, with minimum temperatures between 8 and 16 degrees. Hot but not extreme summers on the coast. Heat pumps extract energy from the outside air even when temperatures are 4-5 degrees. They use this energy to provide heating in winter, cooling in summer, and domestic hot water. Their efficiency is measured by the COP (Coefficient of Performance), which for a modern pump in this climate ranges between 3.5 and 4.5. This means it produces 3.5 to 4.5 kilowatts of heat for every kilowatt of electricity consumed. We work with natural gas, butane, and propane boilers, as well as condensing and electric models. We carry out complete replacements, commissioning, and specific repairs when a boiler fails to ignite or loses pressure.

A fitted condensing boiler costs €400, depending on the brand, power rating, and necessary work. The replacement cost is usually recovered within 4-6 years due to gas savings. Electric underfloor heating for a 90 m² home costs around €4,000 with zoned thermostats. Replacing individual radiators costs €80-€180 each, depending on size and model. Installing a programmable thermostat costs €120-€280, depending on the brand. Manufacturer's official warranty (5-7 years) plus our coverage on labour.

The price for annual maintenance in Vilassar de Mar typically ranges from €160 to €165. The final cost depends on the property's condition, materials, and working time. We always provide a fixed quote before starting. Call us, message us on WhatsApp, or request your quote online — we'll reply in under 10 minutes during business hours. After an initial assessment, the technician will give you a fixed written quote detailing labour, materials, and VAT. We only start work once you approve it. The agreed price will not change unless a different fault requiring your authorisation arises.
