3. BalaNCINg aND SETTINg THE SYSTEM
By setting the bypass to 1, a 1032 l/h flow rate corresponds to a 90 mbar
pressure drop (0.09 bar).
Assuming that ΔP pav = floor-mounted system pressure drop = 0.25 bar,
set the capacity of the Wilo Yonos PARA circulator in order to sure a flow
/h) and a head H = ΔP valv + ΔPpav = 0.09 + 0.25
rate of 1032 l/h (1.03 m
3
= 0.34 bar (≅ 3.4 m CA).
Here below are some tables that report the data for systems selected based
on the requested heating capacity.
Therefore, first use the table or formulas to carry out the setting and then
use the thermometers to make sure the project temperatures of the fluid
are actually reached.
To increase the ΔT of the floor circuits, just reduce the bypass flow rate.
