4.3 - Characteristic curve of the residual
head at the central heating plant
The residual head at the attachments of the MYDENS
boiler with standard pump is given as a graph in figure 4.2.
A modulating pump can be provided on request.
In this case, the field of modulation (detail “x”) can be
verified on the graphics in figure 4.3.
