Explanation
Heat exchanger that, on the primary side, is con-
nected to the district heat network and that, on the
secondary side, delivers the hot water to a com-
mon flow. Several consumers, such as zone con-
trollers, are connected to the common flow.
Heat exchanger that delivers the heat directly to
the consumers (e.g. space heating, d.h.w. heat-
ing, etc.).
Explanation
Pump that supplies tap water via the heat ex-
changer into the storage tank where it is made
available as d.h.w.
Pump that pumps water as a heat carrier. The
water transfers its heat via a coil or storage tank
to the d.h.w. and, therefore, does not get into
contact with the d.h.w.
Explanation
Common term used for coil type and stratification
storage tanks.
