<p>A system, device and method for indicating the performance of a combustion boiler(l) used for heating water, the boiler comprising a burner(2), an air intake for the burner, a flue (3) for exhaust gas from the burner, and a water heating circuit having a flow heating water outlet(4) and heating water inlet (5), the water flowing within the boiler from the water inlet to water outlet past the burner. The system comprises a temperature sensor for obtaining a measurement of combustion air intake temperature (Ta) in the air intake for the burner; a temperature sensor for obtaining a measurement of flue gas temperature (Tg) in the flue for exhaust gas from the burner,- a temperature sensor for obtaining a measurement of heating flow water temperature (Tf ); and a temperature sensor for obtaining a measurement of heating inlet water temperature (Tr). A processor receives inputs from the temperature sensors and provides an output based on the obtained temperature measurements. An indicator (6) receives the output from the processor and provides an indication to a user relating to the performance of the combustion boiler.</p> |
