摘要

Method for cleaning a waste gas heat exchanger (7) of a heating device (1) comprises taking the heating device out of service, filling the heat exchanger with a cleaning liquid over a defined time and bleeding off the liquid. Preferred Features: The heat exchanger is flushed after the liquid is bled off. In the case of a non-condensing calorific value heating device, the waste gas tube connection is closed or connected with a cleaning liquid supply container (9) before filling the heat exchanger. In the case of a condensing calorific value heating device, the condensate runoff is closed or connected with a cleaning liquid supply container (9) before filling the heat exchanger.
