We install the new boiler with updated accessories: an expansion vessel of the correct size, a new safety valve, a gas hose with an accessible shut-off valve, and a forced-draught flue system (horizontal or vertical, according to your community's regulations). We also install an automatic air vent at the highest point of the circuit. Parameters are configured based on the installation type (radiators, underfloor heating, or both), and the heating curve is adjusted to the local climate.

Common repairs include: replacing electro-thermostatic manifold actuators that have failed and are blocking a circuit; replacing the circulation pump when it no longer provides sufficient flow; balancing the circuit when there are thermal imbalances between zones; and complete bleeding when there's air in the system. Leaks in embedded pipes are the most serious, but also infrequent, issues. Quality multilayer pipes are guaranteed for 50 years. For a property on the Costa Blanca with existing underfloor heating that has started to fail (a cold zone that isn't heating, a leak, noise in circulation), diagnosis requires specific tools: a thermal imaging camera to identify malfunctioning circuits, an electronic leak detector to locate loss points without breaking the floor, and manometers to check circuit pressures. In most cases, we can diagnose and repair without lifting the entire floor. When it's time to replace an old boiler, the complete process typically takes one day. We start by cutting off the gas and draining the heating circuit. We dismantle the old boiler, connecting pipes, and obsolete accessories. We clean the space and check the electrical panel's condition to confirm it has capacity for the new boiler (modern modulating boilers consume very little but require specific connections).

Official manufacturer's warranty (3-5 years) plus our labour coverage. For tight budgets, Ferroli and Baxi are reasonable alternatives, with quality noticeably lower than premium brands but sufficient for standard domestic use. Saunier Duval offers excellent value for money, with the ThemaPlus Condens range being a benchmark for medium-sized apartments and the Renova Condens for larger homes.

The price for aerothermal systems in La Trinitat Nova 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. Multilayer pipes for water or heating mesh for electric systems, pressure testing, and thermostats. Calculation of heat loss per room and system sizing based on actual usage.
