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 evacuation system, horizontal or vertical according to 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. Installing a standard bathroom extractor is completed in a single visit; a VMC for renovation requires duct planning. We leave everything connected, tested, and with the correct intake grilles for the system to truly work. Bathroom extractors with a timer or hygrostat that start automatically when humidity rises. Kitchen hoods and extractors with external vents or carbon filters where no duct is available. Controlled Mechanical Ventilation (CMV) systems for homes and renovations, which continuously and silently renew the air throughout the house. We also repair existing equipment: noisy motors, blocked blades, obstructed ducts, and grilles that don't close. Modern homes are increasingly well-insulated, which is excellent for heating bills but creates a problem. The air doesn't renew, and humidity generated from cooking, showering, or breathing remains inside. On the coast, with high ambient humidity for much of the year, this leads to condensation on windows, mould spots in corners and on ceilings. That feeling of stale air typical of apartments closed for months during holiday rentals.

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 excellent 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.
