Hydronics/Water Flow
(SC-1500 / SC-2000)
The chart below represents the pressure drop (Ft of Head) versus the water flow rate (GPM) for the SONIC
TM
SC-1500 and SC-2000 boilers. This information is useful to help size an appropriate circulation pump.
Keep in mind this pressure drop represents the boiler only, additional consideration is needed for any
connecting piping, valves, strainers, couplings, flanges, etc
