3.7 Hydraulic specifications

Depending on the flow, the following diagrams represent:
- the manometric heights of the heating
- loss of load in the boiler.
For a fixed flow, the manometric height available at the boiler outlet
is obtained by taking the difference between the manometric height
of the circulator pump and the loss of load in the boiler.
