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 community's 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. When it's time to change an old boiler, the complete process typically takes one day. We start by shutting off the gas and draining the heating circuit. We dismantle the old boiler, connection pipes, and obsolete accessories. We clean the space and check the condition of the electrical panel to confirm it has the capacity for the new boiler (modern modulating pump boilers consume very little but require specific connections).

For a home on the Costa Blanca with existing underfloor heating that has started to fail (cold zone not heating, leak, circulation noise), diagnosis requires specific tools. A thermal imaging camera to identify non-functioning circuits, an electronic leak detector to locate loss points without breaking the floor. Manometers to verify circuit pressures. In most cases, we can diagnose and repair without lifting the entire floor. The most common repairs are varied. Replacement of electrothermal collector heads that have failed and block a complete circuit, replacement of the circulation pump when it no longer provides sufficient flow, balancing the circuit when there are thermal imbalances between zones. Complete bleeding when there is air in the system. Leaks in embedded pipes are the most serious but also infrequent issues. Quality multi-layer piping has a guaranteed 50-year lifespan. The official RITE certificate we issue upon completion is what your home insurance requires to be up-to-date to cover any incidents related to the boiler. Without a valid certificate, a breakdown causing damage may not be covered. The mandatory inspection is annual for gas boilers with a power output between 20 and 70 kW, which covers the vast majority of domestic boilers.

Official manufacturer's warranty (3-5 years) plus our coverage on labour. Junkers (Bosch) is a second option 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.

The price for aerothermal systems in Centre (l'Hospitalet) typically ranges between €188 and €2240. The final figure depends on the property's condition, materials, and work time.
