Hot water accumulator.

摘要

The domestic water container (22) is formed as a hollow ring, and is located coaxially inside the top of the cylindrical tank (8). The water heated in the solar system is fed into the lower section of a pipe (19), which is located positioned coaxially inside the tank. The pipe extends through the container interior up to near its cover. It has a top and a bottom opening, and several openings (20) in its jacket surface. These are located mainly within the interior of the domestic water container, and some of them have a nonreturn valve.
