The water to be heated is kept separate from the central heating water. The heat imparted during the steam injection is transferred by heat exchangers (210) from heated water to the central heating or hot water. Pref. the steam vol. to be injected is controlled by regulated discharge of water or condensate into the condensate line (112) of the steam network (110,112), with the discharge regulation depending on ambient temp.. The bubbles of steam, formed during the injection, may be comminuted. |
