This chart provides Pump recommendations for SYNC boilers for the Boiler Loop / Space Heating piping.
Based on specific Temperature Rises, this chart includes calculated Gallon Per Minute flow rate, calculated Foot Head Loss and recommended Pump.
The GPM, Ft/Hd and Pump selection is based on Primary / Secondary Boiler Loop piping of maximum 20 feet of straight pipe, 4 - 90° elbows and 2 - full port ball valves.
See the Installation and Operation manual for more details including pipe diameters and piping diagrams.
Reminder: The SYNC boiler requires TWO pump, one for each heating module.
The Pump recommendations listed above are for the individual heating module.
