To ensure safe and efficient operation, a gas boiler must be serviced regularly – at least once per year. Maintenance of gas boilers must be performed by a certified specialist.
Even a few millimetres of soot and a poorly adjusted burner consume 5–10% more in terms of energy. Similarly, gas consumption increases if a component of the heating system, such as a pump, filter or valve, doesn’t work as planned. Maintenance is mandatory after the first year of operation.
