An installed extractor with a timer typically costs between 90 and 180 euros, depending on the model and ducting 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 gas extraction 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.

We start by measuring humidity and checking current extraction points. We propose the simplest solution that resolves the problem, without oversizing. The installation of a standard bathroom extractor is completed in a single visit; a CMV in a renovation requires duct planning. We leave everything connected, tested, and with the correct admission grilles so the system truly works. Modern homes are increasingly well insulated, which is excellent for heating bills but creates a problem. Air is not renewed, and humidity generated from cooking, showering, or breathing remains inside. On the coast, with high ambient humidity for much of the year, this translates into condensation on windows, mould stains in corners and ceilings. That feeling of stifled air typical of apartments closed for months as holiday rentals. We evaluate humidity, airflows, and extraction points to size the correct system.

Saunier Duval offers excellent value for money, with the ThemaPlus Condens range as a benchmark for medium-sized 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. Junkers (Bosch) is the second option with similar quality and slightly more competitive prices. The Cerapur Excellence Compact range is robust and efficient.
