Heater with a premix burner

A heating device has a burner fed by a fuel-air mixture, a combustion chamber, a heat exchanger unit (14) for cooling combustion gas in a low performance range below steam dew point and a bypass device (20) for linking the combustion chamber to a combustion gas eduction device (18) so as to re-heat...

Zusammenfassung:A heating device has a burner fed by a fuel-air mixture, a combustion chamber, a heat exchanger unit (14) for cooling combustion gas in a low performance range below steam dew point and a bypass device (20) for linking the combustion chamber to a combustion gas eduction device (18) so as to re-heat the combustion gas to a value acceptable for a flue connection by introducing heat from the combustion gas.
