Abstract

Die Erfindung betrifft einen gasbeheizten Umlaufwasserheizer, mit einem Rücklaufanschluß (10) und einem Vorlaufanschluß (36) für ein externes Heizungsnetz (12), und mit einem beide Anschlüsse verbindenden, über eine Pumpe (18) und einen von den Verbrennungsgasen beaufschlagten Wärmeübertrager (26) führenden Leitungssystem, das einen Leitungsabschnitt (32) enthält, der eine zwischen Gasbrenner (22) und Wärmeübertager (26) angeordnete Brennkammer (28) kühlend an deren Wänden entlanggeführt bzw. in deren Wände integriert ist.The invention relates to a gas-heated Circulating water heater, with a return connection (10) and a flow connection (36) for an external heating network (12), and with one connecting both connections, via a Pump (18) and one of the combustion gases acted upon heat exchanger (26) leading Line system which contains a line section (32) one between the gas burner (22) and the heat exchanger (26) arranged combustion chamber (28) cooling on the walls guided along or integrated into their walls.

Es wird vorgeschlagen, daß der die Brennkammer (28) kühlende Leitungsabschnitt (32) eingangsseitig an den Ausgang des von den Verbrennungsgasen beaufschlagten Wärmeübertragers (26) angeschlossen ist.It is proposed that the combustion chamber (28) cool Line section (32) on the input side to the output of the the heat exchanger (26) exposed to the combustion gases connected.

Dadurch ist erreicht, daß das an den Brennkammerwänden entlangströmende Wasser im Wärmeübertrager aufgeheizt ist, so daß nur bei extrem niedrigen Rücklauftemperaturen des Heizungswassers Kondensat in geringen Mengen anfällt.

Figure 00000001
It is thereby achieved that the water flowing along the combustion chamber walls is heated in the heat exchanger, so that condensate is obtained in small quantities only at extremely low return temperatures of the heating water.
