We install the new boiler with updated accessories. A correctly sized expansion vessel. A new safety valve. A gas hose with an accessible shut-off valve. A forced-draught flue system, horizontal or vertical according to your local regulations. And an automatic air vent at the highest point of the circuit. We configure parameters based on the installation type (radiators, underfloor heating, or both) and adjust the heating curve to the local climate.

The official RITE certificate we provide upon completion is what your home insurance requires to be up-to-date to cover any boiler-related incidents. Without a valid certificate, a breakdown causing damage may not be covered. Mandatory annual inspection applies to gas boilers with a power rating between 20 and 70 kW, which covers almost all domestic boilers. Aerothermal energy is the most energy-efficient option but requires a higher initial investment and space for the outdoor unit. For complete renovations with new underfloor heating, aerothermal energy is clearly beneficial. For replacing an existing boiler that still functions well with installed radiators, switching to aerothermal makes sense, but only when the time is right for a boiler renewal, not before. When you are building or undertaking a full renovation, the decision about the heating system has one of the most significant impacts on comfort for the next 30-40 years. A decade ago, the automatic answer was radiators with a boiler. Today, water-based underfloor heating combined with aerothermal energy is what we predominantly install in modern new builds on the Costa Blanca, especially in detached houses and large properties. The reasons are varied and all converge on comfort and efficiency.

Junkers (Bosch) is a second choice with similar quality and slightly more competitive prices. The Cerapur Excellence Compact range is robust and efficient. Saunier Duval offers very good value for money, with the ThemaPlus Condens range as a benchmark for medium-sized apartments and the Renova Condens for larger homes. Official manufacturer's warranty (3-5 years) plus our labour coverage.

The price for aerothermal energy in El Prat de Llobregat typically ranges between €188 and €2240. The final figure depends on the property's condition, materials, and labour time. We always provide a fixed quote before starting. Call us, message us on WhatsApp, or request your quote online — we reply in under 10 minutes during business hours. A complete aerothermal installation is a serious project. It starts with calculating the property's thermal loads, sizing the equipment according to actual needs, choosing between radiators only, underfloor heating only, or a combination, planning space for the DHW tank and outdoor unit, and providing a fixed quote.
