From 4 to 400 kW
One service every calendar year
Gas, fuel oil or solid fuel boilers from 4 to 400 kW: one service per calendar year, by a qualified professional. After an installation or a replacement, the first one takes place during the following calendar year at the latest. The log and the reminder list follow that deadline.

The certificate handed over, kept 2 years
The person who serviced the boiler draws up the certificate within 15 days of the visit and hands it to the customer who ordered the service, who keeps it for at least 2 years. The Excel file calculates the hand-over deadline, the log keeps the hand-over date.

Who orders the service
Rented home with its own boiler: the tenant calls the qualified heating engineer of their choice, unless the lease puts the landlord in charge. Shared boiler: the owner or the co-owners’ association. That is the “commanditaire” named on the certificate.

The carbon monoxide reading
Measured in the boiler room, after the adjustments. Below 10 ppm: “La situation est normale”. From 10 to under 50 ppm: abnormal, the flue draught and the room ventilation must be examined. 50 ppm or more: serious danger, boiler kept off. The Excel file writes the exact statement.

A comparison with the reference
Efficiency and emissions are read from the tables of the order, then compared with a reference: for gas and fuel oil, a condensing boiler of the same power and 35 or 90 mg/kWh of nitrogen oxides. Below 70 kW, the energy class appears too. The advice stays indicative.
