Glossary
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 pre-
controlled or common flow. The flow then supplies
the hot water to several consumers that are con-
trolled by zone controllers, etc.
Heat exchanger that delivers heat directly to the
consumers (e.g. space heating, d.h.w. heating,
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 supplies water from the heat source
(heat converter) to the consumers. The pump can
be located either in the flow or the return.
Pump that supplies water as a heat conducting
medium. The water transfers its heat via a coil or
storage tank to the d.h.w. without getting in direct
contact with it.
Explanation
Common term used for coil type and stratification
storage tanks.
