VTC 422 3-way mixer ESBE

The VTC 422 3-way mixer ESBE It regulates the flow temperature and/or the return temperature increase in the heating circuit.

The use as Return flow increase This serves to quickly reach and maintain the desired minimum temperature. This prevents soot buildup and condensation, and increases the efficiency and lifespan of the fireplace.

This is achieved by mixing hot supply water into the cold return water.

This addition is made variably using a mixer.
