Hot-water saving system - has chamber downstream of heater with plug alternately shutting hot and cold pipes

摘要

The system saves hot water in a system incorporating a boiler or geyser from which pipes lead to a discharge tap also supplying cold water. Downstream of the heater is a chamber (4) into which hot (5') and cold (2') water pipes discharge and containing a plug alternately shutting off the hot and cold water. - This keeps the hot-water pipe shut under spring action (11) in the rest position, with the cold-water pipe shut-off in opposition to the spring. The chamber is connected by a single pipe (6) to the discharge tap.
