DESCRIPTION
Indirect substation for single and multifamily
houses with up to 7 flats.
District heating substation for indirect
heating and instantaneous domestic
hot water with thermostatic control.
The Termix VVX-B is used if a heat exchanger
is required or on a conversion
to district heating where the existing
equipment is unsuitable for direct
connection. The domestic hot water is
prepared in the heat exchanger and the
temperature is regulated with a thermostatic
control valve. The patented sensor
accelerator accelerates the closing of
the thermostatic valve and protects the
heat exchanger against over heating
and lime scale formation.
The VVX-B substation can be used together
with the Termix distribution units
for floor heating or radiator heating.
