N.B.:
Max. water temperature for the heating system is 110
°
C.
NOTE:
When priority ends with high temperature water in the boiler, the thermal inertia which
develops when the circulator stops could inhibit the boiler itself (total switch-off) owing to
activation of the safety thermostat at 100˚C. To prevent this inconvenience, the plant has been
equipped with a heater thermostat called circulator thermostat (TC). When the boiler
temperature exceeds the value preset by this thermostat, the heater circulator is actived until
the temperature drops below that value.
2.02 Pressure drop
(fig. 3)
Pressure drops according to the boiler size are specified on the following diagram and refer to
temperature difference between flow and return comprises between 10 and 20
°
C.
