Termix VVX-ID

Application
Termix VVX is a complete solution for hot water and heating, offering optimum safety, efficient heat transfer, service-friendly construction and a compact design. The district heating unit is used on a conversion or a new connection to district heating.

District heating (DH)
The district heating unit is provided with fitting pieces and sensor pockets for installation of heat meters, and horizontally-mounted strainers on all circuits. Primary and secondary connections are optionally up and/or down. Cold and hot water connections are up as standard, but can locally be easily changed to down (also available as accessories with connectors that are both up and down).
​​​​​​​
Heating (HE)
The heating circuit consists of a plate heat exchanger, safety valve, manometer, thermometer (supply temperature), shut-off valves, air vent valve, expansion vessel and circulation pump. The supply temperature is regulated electronically with outdoor sensors and supply sensors. Various sizes of heat exchangers can be used, depending on the capacity needed.
​​​​​​​
Domestic hot water (DHW)
Hot water is produced in the heat exchanger and the temperature is regulated with a self-acting thermostatic valve that checks the hot water temperature using the flow control principle. Rapid closure of the thermostat valve protects the heat exchanger from overheating and scaling. The control valve guarantees a stable hot water temperature, even during a changing duty cycle. The heat exchanger cools the district heating water very effectively, which provides excellent operational economy. The thermostat valve also functions as a bypass, keeping the district heating culvert heated. This means shorter waiting times during the summer when the district heating is supplied at a lower temperature.

Options
​​​​​​​The district heating unit can also be supplied with a thermal bypass that is fitted before the heat meter.
