Boilers, gas and aerothermal heating
The boiler is the home appliance with mandatory maintenance and the most inconvenient failures: it never breaks down in June. Aerothermal heating has entered strongly as the efficient alternative in the city.
Mandatory inspections
Gas installations require periodic inspections depending on type, power and age, and the community or the gas distributor can demand them. Keep the certificate current: without it, no sale and no calm insurance.
Replace or repair
With an old boiler and an expensive part, the math usually tips toward replacing for efficiency. Always ask for both options priced: the good technician offers both unprompted.
Aerothermal and communities
Individual aerothermal units work well in the city and subsidies have accelerated adoption; in buildings, shared central heating is another conversation that starts at the owners' meeting.
