General description and
application
Maximum operating
parameters
District heating transfer stations provide the link
between district heating suppliers and customers’
systems. They incorp orate the necessary equipment
to tailor the supplied heat to the needs of the object
premises as specied in the heating supply contract.
In this they need to comply with all applicable standards and with the supplier’s technical connection
conditions.Indirect connections (in which district
heating and in-house systems are hydraulically isolated)incorporate components to separate the systems (heat exchanger), to limit the ow volume to
that specied in the contract, regulate the se condary
supply temperature and measure the energy consumption. The system described here is a standard
type in which one dierent types of applications
can be connecte d on the secondary.Thus, this system
is especially suitable for biomass applications.

Hot water drawn from the pipeline of the local or
district heating supply company is fed into the
station at an appropriate temperature and pressure,
which may be higher in winter than in summer.
In the primary supply line this hot water will ow
through a shut-o valve and a dirt trap / strainer.
The supply and return lines will incorporate a
thermometer and a manometer to register the
temperature and pressure.
There will also be regulatory equipment in the
return lines of the primar y as specied by the circuit
design.
The cooled heating water then ows back to the
local or district heating supply company via the
primary return pipe.
On secondary side dierent types of applications
and systems can be connected.
