WENTA · WBC
Cylinder with twin coil
Two heat sources, one buffer of hot water.
The WBC series shares the robust design of the WBT but adds a second heat exchanger. That makes combining two heat sources straightforward: a boiler with solar collectors, or a heat pump. Connect the lower coil to the renewable source and the upper coil to the back-up heat.
