Abstract (en)
[origin: EP0109620A2] Fuel-heated heat source, in particular a circulating water heater which has a combustion chamber, in which a heat exchanger acted upon by a burner is arranged, the combustion chamber being connected to the atmosphere only via a fresh air supply pipe and a waste gas outlet pipe, and a fan being provided in one of the two pipes. Between the two pipes, there is arranged a bypass flap which bypasses the heat exchanger in terms of flow and which is coupled positionally to an air flap, the latter governing the air supply to the combustion chamber. <IMAGE>
