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 community's regulations. And an automatic air vent at the highest point of the circuit. We configure parameters according to the installation type (radiators, underfloor heating, or both) and adjust the heating curve to the local climate.

When it's time to replace an old boiler, the entire 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 condition to confirm it has sufficient capacity for the new boiler (modern modulating heat pumps consume very little but require a specific connection). Aerothermal heating is the most energy-efficient option but requires a higher initial investment and space for the outdoor unit. For full renovations with new underfloor heating, aerothermal heating clearly pays off. For replacing an existing boiler that still functions well with installed radiators, switching to aerothermal heating makes sense but only when the natural time to renew the boiler arrives, not before. When 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, underfloor water heating combined with aerothermal systems is what we primarily install in modern new builds on the Costa Blanca, especially in chalets and large homes. The reasons are several and all converge on comfort and efficiency.

Junkers (Bosch) is a second option with similar quality and slightly more competitive prices. The Cerapur Excellence Compact range is robust and efficient. For tighter budgets, Ferroli and Baxi are reasonable alternatives, with quality notably inferior to premium brands but sufficient for standard domestic use. Saunier Duval offers a very good quality-price ratio, with the ThemaPlus Condens range as a benchmark for medium-sized apartments and the Renova Condens for larger homes.

The price for aerothermal heating in Les Roquetes typically ranges between €188 and €2240. The final figure depends on the property's condition, materials, and working time.

A complete aerothermal installation is a serious project. It starts with calculating the home's thermal loads, sizing the equipment according to actual needs, choosing between radiators only, underfloor heating only, or a combination, planning space for the Domestic Hot Water (DHW) tank and the outdoor unit, and providing a fixed quote.
