AquaMotion AMH2K-R Dedicated Return Line TANKLESS Water Recirculation System

The AquaMotion AMH2K-R is designed for plumbing systems with a dedicated return line and a large hot water tank or a tankless water heater. The pump installs into the dedicated return line at the hot water heater. Stainless 3 speed circulator, aquastat, timer, 3/4 inch FNPT flanges and a 10 ft. line cord. Meets Title 24 in California. Good for up to 600 feet of pipe length. This kit has a timer for activation.

The AMH2K-RN is an on-demand version of the AMH2K-R model system and does NOT have a timer. On-demand gives you the ability to control system activation through a switch or motion sensor. When activated, the pump shuts off after 5 minutes or when the water temperature reaches 105 F.  Additional on-demand switches, motion sensors, etc (AMK- parts below) have to be purchased to activate the pump.
