2.0 Functional description

Domestic hot water module with heat exchanger and
thermostatic control. Designed for wall-mounting.
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.
