8.3 Connection between multiple
buffer storage tanks
Parallel connection
When there are several buffers, parallel connection
(top with top and bottom with bottom) is usually the
better solution. With a parallel connection, the entire
buffer volume is available to installed heat exchangers
such as solar heat exchangers or internal water heat
exchangers and suspended hot water tanks.
If two buffer storage tanks of different dimensions are
connected in parallel, then the flow must be connected
to the higher buffer or the lower buffer must be raised
so that the upper connection can be horizontal.
