Information regarding continuous output of the upper indirect
coil
When engineering systems with the specified or calculated continu-
ous output, select a matching circulation pump. The stated continu-
ous output is only achieved when the rated boiler heating output ≥
continuous output.
Note
The cylinder is also available as Vitocell 100-W, type CVUB in white.
The Vitocell 100-W, type CVUC-A is only available in white.
