Vitocell 300-B

EVB Series

Vertical indirect-fired domestic hot water storage tank

of high-grade stainless steel with two coils

One heat exchanger coil facilitates heat transfer from the solar

collectors to domestic hot water, a second heat exchanger coil

allows reheating of the water content by the hot water heating

boiler.

System Design Guidelines Sensor well Temperature and pressure relief valve The supplied stainless steel sensor wells are to be used for control sensors to ensure maximum operational safety. The top sensor well is used for the DHW sensor connected to the boiler control. Should the supplied sensors not fit into the sensor wells, other stainless steel sensor wells must be used. For solar heating systems, Viessmann recommends placement of the DHW tank temperature sensor in the solar collector return.
