VTC 422 3-way ESBE
VTC 422 3-way mixing valve ESBE
The VTC 422 3-way mixing valve ESBE regulates the flow temperature and/or the return temperature increase in the heating circuit.
The use as Return flow increase It helps quickly reach and maintain the desired minimum temperature. This prevents the formation of soot and condensation and increases the efficiency and lifespan of the fireplace.
This is done by mixing hot flow water into the cold return flow.
This mixing is done variably using a mixer.
