Selecting the cylinder type

3.1 Selection according to N

General information

The detailed specification and performance parameters for the DHW
cylinder can be found in the datasheets. The following tables help
with initial selection.

DHW cylinder selection

The calculated demand factor N (see from page 13) is used to
select the DHW cylinder performance factor N
be found in the first column of the following selection diagrams.
DHW cylinders that have a corresponding performance factor are
marked grey.

Example:
DHW heating in a two-family house in conjunction with a solar ther-
mal system
Demand factor N = 2.3 1
Selection: Vitocell 100-B, 400 l 2 (from Vitocell 100 selection dia-
gram) or Vitocell 300-B, 300 l 2 (from Vitocell 300 selection dia-
gram).
In the top line, the flow temperature of 70 °C 3 required for this out-
put can now be read for Vitocell 100-B, 400 l with a performance fac-
tor N = 2.5 or of 90 °C 3 for Vitocell 300-B, 300 l with a perform-
L
ance factor N = 2.4.

The selection of the DHW cylinder should be checked using the
specification in the datasheet.
