Fact sheet
Termix Novi
Instantaneous water heater for flats, single-family houses and small apartment buildings with up to 4 flats
Application
The Termix Novi is an instantaneous
water heater featuring superb heat
extraction and high performance.
The Termix Novi is suitable for flats,
single-family houses as well as for
small apartment buildings. The water
heater is available in two sizes, either
for 1 apartment, or up to 4 apartments.
The Termix Novi is applicable for decentralized heating systems – as well
as for district heating networks with
summer operation at low temperatures or with changes in differential
pressure. The heat exchanger in Termix
Novi cools the district heating water very efficiently, thereby creating
a very good operation economy.
Domestic hot water (DHW)
The domestic hot water is prepared
in the heat exchanger and the temperature is regulated by a flow-compensated temperature controller
with a integrated differential pressure
controller. The Danfoss IHPT valve
ensures a stable hot water temperature by varying differential pressure
without the need for readjusting
the valve. This protects the heat
exchanger against overheating and
lime scale formation. Furthermore
the IHPT valve has an integrated idle
temperature controller, which keeps
the house supply line warm. This
shortens the waiting periods during
summer when the heating system is
in reduced operation, which is ideal
where high comfort is requested.
Options
The water heater can be supplied
with a built in non-return valve and
safety valve mounted in the cold
water supply. The water heater can
also be supplied with a thermostatic
circulation valve and a non-return
and pressure equalizer (GTU).
Construction
All pipes are made of stainless steel.
The connections are made by nuts
and gaskets. The Termix Novi is delivered with an attractive grey full insulation in modern design, emphasising
the high level of quality and comfort
which characterises this product.
