1536554 Heat exchangers for heating water P E REGAMEY 12 Dec 1975 [16 Dec 1974] 51012/75 Heading F4A In a heating system in which steam is condensed in a heat exchanger, the heat output being controlled by regulating the outflow of condensate to the steam/condensate return line, the condensate is heated to the steam temperature before being released to the return line. The condensate may be collected in a vessel or heat exchanger heated by live steam or independent means, e.g. an immersion electrical heater.
