Abstract: Method (100) for measuring the flow rate of a fluid in a conduit system (6) of a combustion appliance (1), in particular a gas boiler, the method (100) comprising measuring (S101) a first temperature value (T1) of the fluid at a first point (P1) of the conduit system (6) by a first temperature sensor (2) and generating a first temperature signal (S1); measuring (S102) a second temperature value (T2) of the fluid at a second point (P2) of the conduit system (6) by a second temperature sensor (3) and generating a second temperature signal (S2), the second point (P2) being downstream the first point (P1); calculating (S103) a time delay (Δt) between the temperature measurement at the first point (P1) and at the second point (P2); and determining (S104) the flow rate based on said time delay (Δt) and a volume of the fluid in the conduit system (6) between the first point (P1) and the second point (P2).
