摘要

The heating system for drinking water is part of an overall hot and cold water system. A three-way valve (46) is fitted in the drinking water collection line (10). Its first path is an input from the collection line. Its second path is connected to the output line (20) of the reaction cavity (6). Its third path is connected via a bypass line (47) and a backflow preventer (48) to the cold water line (11) of the charging pump (4).
