PUMP
The character curve of the heating circulation pump built
into the GHISS .. . .. PV type devices can be seen in the
following illustration.
The pump has III levels; it is always practical to use the
lower level that still provides for the heating system; this
way you can save electric energy.
The pressure-loss of PV-type boilers:
Upon the first start-up of the boiler and after a longer
shut-down, it is practical to check the turnability of the
axle of the pump with the help of a screwdriver.
It is forbidden to operate the pump without water!
The hydraulic loss of the boilers
With the exception of the GHISS .. . .. PV type devices,
