A correctly sized expansion vessel. A new safety valve. A gas connector with an accessible stopcock. A flue gas evacuation system with forced draught, horizontal or vertical as per 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 is the most energy-efficient option but requires a higher initial investment and space for the outdoor unit. For comprehensive renovations with new underfloor heating, aerothermal is clearly worthwhile. For replacing an existing boiler that still works well with installed radiators, switching to aerothermal makes sense, but only when the natural time comes to replace the boiler, not before. 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 that causes damage might not be covered. The mandatory inspection is annual for gas boilers with a power output between 20 and 70 kW, which covers almost all domestic boilers. When you build or undertake a full renovation, the decision about the heating system is one that has the most significant impact on comfort for the next 30-40 years. A decade ago, the automatic answer was radiators with a boiler. Today, water underfloor heating combined with aerothermal is what we mostly install in modern new builds on the Costa Blanca, especially in chalets and large homes. The reasons are several, all converging on comfort and efficiency.

Official manufacturer's warranty (3-5 years) plus our labour coverage. The most common repairs include several. Replacement of electrothermal manifold heads that have failed and block a whole circuit, replacement of the circulation pump when it no longer provides sufficient flow, circuit balancing 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, type of breakdown. Quality multilayer piping has a guaranteed 50-year lifespan. For tighter budgets, Ferroli and Baxi are reasonable alternatives, with noticeably lower quality than premium brands but sufficient for standard domestic use.

The price for underfloor heating in La Nova Esquerra de l'Eixample typically ranges between €196 and €4095. The final amount depends on the property's condition, materials, and labour time. We always provide a fixed quote before starting. Many of these homes have installations from the 70s or earlier that require a complete update. We offer a free initial assessment and a detailed breakdown quote.
