HEIZUNGSEINRICHTUNG MIT KERAMISCHEN BRENNKOPF SOWIE MIT EINEM BRENNRAUM UND EINEM REKUPERATOR AUS KERAMIK

摘要

A heating system for supplying utility water and a heating fluid for space heating purposes comprises a unit fired by a burner and having a recuperator traversed by the combustion gases and forming a first zone for heating the space-heating fluid and a second zone for heating the utility water. According to the invention, a heat exchanger is provided along the path of the utility water delivered from the second zone to a reserve tank and the heat exchanger is connected in a bypass across the feed and return lines of the heating fluid circulating path. A control responsive to the temperature in the tank regulates the flow through the bypass while a further temperature control responsive to the feed side temperature of the space-heating circulation path controls the fuel supplied to the burner and the rate of combustion gas flow through the heat exchanger.
