摘要

The water heater is run by a solar collector(5), and the hot water produced is stored in a storage-collector (9). The water pipe system (1) incorporates a branch (18), a backflow check valve (3) and a branch pipe (12) with pressurized hot-water tank (11) and backflow check valve (16) directly and or by successive pipes. The backflow check valve, preferably in the form of a throttle valve (14), is connected to the other, second branch of the branch piece .
