Aerothermal systems are the most energy-efficient option but require a higher initial investment and space for the outdoor unit. For full renovations with new underfloor heating, aerothermal is clearly beneficial. For replacing an existing boiler that is still working well with installed radiators, switching to aerothermal makes sense but only when the boiler reaches its natural end of life, not before. When it's time to replace an old boiler, the complete process typically takes one day. We start by shutting off the gas and draining the heating circuit. We remove the old boiler, connecting pipes, and obsolete accessories. We clean the space and check the electrical board's condition to confirm it has sufficient capacity for the new boiler (modern ones with modulation pumps consume very little but require a specific connection). Common repairs include: Replacing electrothermal collector heads that have failed and are blocking a complete circuit, replacing the circulation pump when it no longer provides sufficient flow, balancing the circuit when there are thermal imbalances between zones. Complete bleeding when there is air in the system. Leaks in embedded pipes are the most serious but also infrequent issues. Quality multilayer pipes have a guaranteed lifespan of 50 years.

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