AquaMotion AMH2K-7 Dedicated Return Line Water Recirculation System
The AquaMotion AMH2K-7 is designed for plumbing systems with a dedicated return line and a hot water tank (non-tankless). The pump installs into the dedicated return line at the hot water heater. It's a fully automatic stainless union pump with an Aquastat/switch, built-in timer and long tail pieces for mounting. Meets Title 24 in California. Good for up to 250 feet of pipe length. This kit has a timer for activation.
The AMH2K-7N is an on-demand version of the AMH2K-7 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.

| #1 | Q: How much horsepower does AMH2K7N have? How long does it take to heat up a 75 ft 3/4 in line after push of button? My system is hardwired with button. Can I connect a hardwire button to this unit? A: Its a fractional HP motor (HP not listed by AquaMotion). 0.60 amps @ 120 VAC. For 75 ft of pipe you have less than 2 gallons of water. Assuming the mid flow rate of 6 GPM that would take around 20 seconds. In our experience its a little more than that. No, you cannot use your hardwired button. The pump needs a control that cycles power to it. Asked on 2021-02-22 by Ed |
