Information regarding the upper indirect coil
The upper indirect coil is designed for connection to a heat genera-
tor.
Information regarding the lower indirect coil
The lower indirect coil is designed for connection to solar collectors.
To install the cylinder temperature sensor, use the threaded elbow
with sensor well included in standard delivery.
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
The versions with 300 and 400 l capacity are also available in white
as Vitocell 100-W.
