Information regarding continuous output
When designing systems with the specified or calculated continuous
output, select a matching circulation pump. The stated continuous
output is achieved only if the rated boiler heating output is ≥ the con-
tinuous output.
Note
Up to 300 l cylinder capacity also available as Vitocell 300-W in
