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. 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 a specific connection). Yes, with chemical barrier injection methods and waterproofing mortars. We guarantee the treatment for 5 years. Painting over it without treating the damp never works, it always returns.

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