A timed extractor installed typically costs between 90 and 180 euros, depending on the model and duct difficulty. We provide a free quote after inspecting the installation point. We install the new boiler with updated accessories. A correctly sized expansion vessel. 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.

Bathroom extractors with timers or hygrostat that switch on automatically when humidity rises. Kitchen hoods and extractors with external outlets or carbon filters when no duct is available. Mechanical ventilation systems (MVHR) for homes and renovations, which continuously and silently renew the air throughout the house. We also repair existing equipment: noisy motors, blocked fans, clogged ducts, and grilles that don't close. Modern homes are increasingly better insulated, which is excellent for heating bills but creates a problem. The air is not renewed, and humidity generated from cooking, showering, or breathing remains indoors. On the coast, with high ambient humidity for much of the year, this leads to condensation on windows, mould stains in corners and ceilings. That feeling of stuffy air typical of apartments closed for months for holiday rentals. We assess humidity, airflow, and extraction points to correctly size the system.

For tighter budgets, Ferroli and Baxi are reasonable alternatives, with noticeably lower quality than premium brands but sufficient for standard domestic use. Saunier Duval offers very good value for money, with the ThemaPlus Condens range as a benchmark for medium-sized 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.
