A correctly sized expansion vessel. A new safety valve. A gas flexible hose with an accessible shut-off valve. A flue gas evacuation system with forced draught, horizontal or vertical depending on 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.

Aerothermal systems are the most energy-efficient option but require a higher initial investment and space for the outdoor unit. For full renovations with new underfloor heating, aerothermal systems are clearly cost-effective. For replacing an existing boiler that is still working well with installed radiators, switching to aerothermal makes sense but only when the boiler naturally reaches the end of its life, not before. When it's time to replace 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, connecting pipes, and obsolete accessories. We clean the space and check the electrical panel's capacity for the new boiler (modern modulating pump boilers consume very little but require a specific connection). For a property on the Costa Blanca with existing underfloor heating that has started to fail (cold spots, leaks, circulation noise), diagnosis requires specific tools. A thermal imaging camera to identify non-functioning circuits, an electronic leak detector to locate points of loss without breaking the floor. Manometers to check circuit pressures. In most cases, we can diagnose and repair without having to lift the entire floor.

Official manufacturer's warranty (3-5 years) plus our coverage on labour. The most common repairs include several. Replacement of electrothermal manifold heads that have failed and block a complete circuit, replacement of the circulation pump when it no longer provides sufficient flow, circuit balancing when there are thermal imbalances between zones. Full bleeding when there is air in the system. Leaks in embedded pipes are the most serious but also infrequent breakdowns. Quality multilayer piping has a guaranteed 50-year lifespan. Junkers (Bosch) is a second option with similar quality and slightly more competitive prices. The Cerapur Excellence Compact range is robust and efficient.

The price for radiators in La Trinitat Nova typically ranges between €174 and €3360. The final amount depends on the property's condition, materials, and labour time. We always provide a fixed quote before starting. Many of these buildings have installations from the 1970s or earlier that require a complete upgrade.
