We install the new boiler with updated accessories. A correctly sized expansion tank. A new safety valve. A gas hose with an accessible shut-off valve. A forced draught flue gas extraction 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 type of installation (radiators, underfloor heating, or both) and adjust the heating curve to the local climate.

Aerothermal heating is the most energy-efficient option but requires a larger initial investment and space for the outdoor unit. For comprehensive renovations with new underfloor heating, aerothermal clearly pays off. For replacing an existing boiler that is still working well with installed radiators, switching to aerothermal makes sense but only when the boiler naturally needs renewing, not before. 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, connection pipes, and obsolete accessories. We clean the space and check the electrical panel to confirm it has the capacity for the new boiler (modern ones with modulation pumps consume very little but require a specific connection). If your atmospheric water heater is over 12 years old and still works, it remains legal as long as you don't renovate. However, it's advisable to schedule a replacement because parts are scarce and any serious breakdown will require mandatory replacement.

Saunier Duval offers excellent value for money, with the ThemaPlus Condens range as a reference for average-sized flats and the Renova Condens for larger homes. For tighter budgets, Ferroli and Baxi are reasonable alternatives, with noticeably lower quality than premium brands but sufficient for standard domestic use. Junkers (Bosch) is the second option with similar quality and slightly more competitive prices. The Cerapur Excellence Compact range is robust and efficient.

The price for post-construction cleaning in Porta typically ranges between €61 and €555. The final figure depends on the property's condition, materials used, and working time. We always provide a fixed quote before starting. Gas water heaters have two clear advantages. First, they provide instant hot water without waiting for a tank to fill, which is convenient for large families. Second, the cost per litre of hot water is lower than with electricity if you use water frequently. The disadvantage is the complexity of installation. It requires a gas connection, adequate ventilation, a flue for smoke extraction (chimney or forced draught), and mandatory annual legal maintenance. Professional calculation considers all these factors and correctly sizes the equipment. The budget difference between well-sized and poorly-sized equipment may seem significant initially. The real cost is ultimately paid by the end customer who visits the shop or restaurant. A poorly air-conditioned venue loses customers in summer when the heat becomes unbearable. For hospitality, where customer comfort directly determines revenue, the right equipment is an investment, not an expense.
