Grundfos Hot Water Circulating In-Line Pumps For Systems With Return Line.
For Systems With Return Line The hot water side of each fixture (faucet, shower or other appliance) must be placed in a continuous loop by connecting a hot water return line from the last fixture to the water heater.
Grundfoa clip-on aquastats automatically turn the circulator "OFF" when the line temperature exceeds 105 degrees F. and "ON" when it falls below 85 degrees. Clip-on mount for 1/2" and 3/4"I.D. copper tubing
