DSA HOME

Wall Mounted Station

General description and
application

Maximum operating
parameters

Danfoss district heating substations provide the
link between district heating suppliers and cus­tomer installations. They contain all the necessary
equipment to adjust the heat supplied for the
needs of the object premises as specied in the
heating supply contract. In this respect they must
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 that separate the sys­tems (heat exchanger), limit the ow volume to
that specied in the contract, regulate the sec­ondary supply temperature and measure energy
consumption.

The DSA HOME is designed for use in high-param­eter district heating networks. It is suitable for
heating single family houses. It is an alternative
solution to oil or gas boilers. The DSA HOME is
prepared for heating or heating and domestic
hot water applications. Its wall-mounted con­struction saves space needed for installation and
servicing.
