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 is still working well with installed radiators, switching to aerothermal makes sense but only when the natural time to renew the boiler arrives, 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 condition of the electrical panel to confirm it has capacity for the new boiler (modern ones with modulation pumps consume very little but require specific connection). 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.

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