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 system, horizontal or vertical depending on 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.

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 condition of the electrical panel to confirm it has capacity for the new boiler (modern ones with a modulating pump consume very little but require 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 clearly pays off. For replacing an existing boiler that is still working well with installed radiators, switching to aerothermal makes sense, but only when it's the natural time to renew the boiler, not before. Yes, with chemical barrier injection methods and waterproofing mortars. We guarantee the treatment for 5 years. Painting over without treating the damp never works, it always returns.
