Termix One Solar
Domestic hot water module for flats, single-family houses and apartment buildings with up to 10 apartments
Application
The Termix One Solar is an instantaneous water heater, featuring superb
heat extraction and high performance.
The Termix One Solar is applicable
for heating systems with buffer accumulators, solar systems or for other
heat sources, where a very low return
temperature is preferred. The water
heater is available in three sizes, either
for 1 apartment, for 1-4 apartments or
for 5 up to 10 apartments. The large
heat exchanger cools out the water
in the primary return line very efficiently, thereby creating a very good
operation economy. A flow switch in
cold water mains is controlling the
primary heating pump. An optional
circulation pump together with a thermostat can maintain the circulating
temperature at a desired temperature.
Domestic hot water (DHW)
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 control valve and
protects the heat exchanger against
overheating and lime scale formation.
The sensor accelerator and the thermostatic control valve also works as
a bypass keeping the heat exchanger
and supply line warm. This shortens
the waiting periods. The sensor accelerator helps to ensure a stable hot
water temperature by varying loads,
flow temperatures and differential
pressure without the need for readjusting the valve. There is no additional pressure loss on the secondary
side of the DHW heat exchanger with
a thermostatic control. Therefore this
type of regulation can be used by low
pressure in the cold water mains.
Options
The water heater can be supplied with
built in non-return valve and safety
valve mounted in the cold water supply.
Construction
All pipes are made of stainless steel.
The connections are made by nuts
and gaskets. The Termix One Solar is
delivered with an attractive steel grey
cover in modern design, emphasising
the high level of quality and comfort
which characterises this product.
