In this Basic Documentation, the following key terms are used:
Term Explanation
Heat converter 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. The flow then supplies the hot water to
several consumers that are controlled by zone
controllers, etc.
Heat exchanger Heat exchanger that delivers the heat directly to
the consumers (e.g. space heating, d.h.w. heat-
ing, etc.).
Term Explanation
Storage tank charging pump Pump that supplies tap water via the heat ex-
changer into the storage tank where it is made
available as d.h.w.
Intermediate circuit pump Pump that supplies water as a heat carrier. The
water transfers its heat via a coil or storage tank
to the d.h.w. without getting in direct contact with
it.
