Termix VVX-B HWP

Application
The Termix VVX-B is a complete solution for hot water and space heating with optimal safety, efficient energy transfer, service-friendly construction and a compact design. The substation is used if a heat exchanger is required or on a conversion to district heating where the existing equipment is unsuitable for direct connection.

District heating (DH)
The substation is prefabricated with a differential pressure controller, valve with actuator and safety function, a fitting piece and sensor pockets for insertion of a heat meter as well as strainers and ball valves.
​​​​​​​
Heating (HE)
The heating side consists of a plate heat exchanger, safety valve, manometer, thermometers, ball valves, drain valve, air valve and circulation pump. The temperature of the heating is controlled by an electronic controller with an outdoor temperature sensor.
​​​​​​​
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 Danfoss AVTB valve and protects the heat exchanger against overheating and lime scale formation. 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. The heat exchanger cools the DH water very efficiently, thereby creating a very good operating economy. The sensor accelerator and AVTB valve also works as a bypass keeping the house supply line warm. This shortens the waiting periods during summer when the heating system is in reduced operation.
