Domestic water supply with pump and storage lays circulation line parallel to hot water up to wall tap point with routing elbow and time-switched pump.

摘要

The circulating line runs parallel to the hot water line just short of the most frequently used tap points (e.g. shower or wash place). At this point the line terminates in a wall disk in which a routing elbow leads the hot water circulation direct to the water tap point. The circulation line is of much smaller diameter than the hot water line and the regulating pump is fitted out with an electronic time switch.
