It is important for the hot water reservoir according to the invention that the bottom region 1.1 is designed to be penetrated by the deflecting device 3 at a further point at a distance from the supply pipe 2, and this also applies to all embodiments. This can be seen particularly easily in fig. 2.

The supply pipe 2 is preferably designed to run horizontally in the region of the feed pipe through the base region 1.1, and said region is also preferably arranged offset with respect to the vertical main axis of the container 1, in which region the base region 1.1 is designed to be penetrated by the supply pipe 2.

Furthermore, the steering device 3, which is preferably formed from plastic, preferably has an approximately cylindrical outer contour with a vertical column main axis.

It is also preferred that a further location, at which the bottom region 1.1 is configured to be pierced by the deflecting device 3, is arranged in alignment with the vertical main axis of the container 1. Furthermore, a pipe socket 4 with a preferably screwable cover element 5 is preferably arranged on the bottom region 1.1 for introducing and fixing the deflection device 3.

The hot water reservoir according to the invention according to the embodiment shown in the drawing functions as follows:

relatively cold return water from the heating circuit is pumped by a heating circuit pump (not shown in the figures, but generally known) via the supply pipe 2 into the container 1 and there in particular into the first flow space 3.1 of the diverting device 3. From there, the water flows downwards and flows through openings in the wall 6 into the second flow space 3.2. Starting from the second flow space 3.2, the water is discharged in all directions with uniform distribution from the discharge opening 7.1 of the distributor head 7 and thus from the deflection device 3. This allows relatively cold water to be introduced into the container 1 in such a way that the temperature layer present there remains as undisturbed as possible.
