摘要

The storage layer comprises a conducting pipe running diagonally to a coiled section along the tank wall. The pipe is placed at a distance to the tank wall at the lower end. The tank is provided with a supply line for hot water flow in its upper area, where supply line runs within the conducting pipe. The conducting pipe has a pipe wall independent of the tank wall over the entire length. The cross section of the conducting tube is reduced from bottom to top.
