The AquaMotion AMH2K-RN is designed to deliver ON-DEMAND hot water quickly at all points of use between the hot water heater and the dedicated return line. The built-in pump timer gives the homeowner the ability to have the system operate at the times when hot water is needed. ON-DEMAND gives the homeowner the ability to manually activate the system through a wireless controller. It does not include a timer. When activated, the circulator run time is 5 minutes or until the water temperature reaches 105°F. ON-DEMAND is preferred over pumps with timers when you are trying to save money on electricity.
A controller is required for the AMH2K-RN. Aquamotion offers three different controller types as well as the option to add an additional controller for their ON-DEMAND pumps. These include a wireless button and receiver (AMK-WB), a wireless wall switch and receiver (AMK-WS) and a smart plug (AMK-SM). Additional controllers (wireless button AMK-WBR and Wall Rocker Switch AMK-WSR) are also available for additional installation.
The AMH2K-RN is for use with large storage tanks or tankless water heaters with a dedicated return line. This is a 3-pipe system that includes a hot water line, a cold water line, and a dedicated return. This system creates a loop from the water heater to the faucet and back again. The unused hot water is drawn back through this loop by the pump, so when you turn on your hot water faucets, you get hot water quickly. Water is not left in the pipes to get cold, and you waste less water because you don’t have to wait.
Water savings can be as great as 12,000 – 15,000 gallons per year with 4-5 taps in a home. As many homeowners know, you can turn on the faucet and wait for the water to heat up for a very long time - sometimes more than 2 or 3 minutes. That waiting time is wasting energy and countless gallons of water!
All of the moving parts of the AquaMotion AMH2K-RN recirculator are housed in a "Green Eco Cartridge Design". It is the only field serviceable and replaceable cartridge available. With this design, simply remove the rotor assembly, flush the cartridge with water and reinstall it. Simple, cost-effective, patented technology!
Requirements for using the AMH2K-RN include a min./max. water pressure of 20 PSI / 125 PSI with a maximum water temperature of 230°F. The AMH2K-R includes the following:
- AMR-S3FVALT1 AquaMotion Pump (return line installation), 10 ft line cord
- 3/4" NPT Female Stainless Flange Kit
- Installation and Operating Instructions
Here is a quick reference to confirm that the AMH2K-RN hot water recirculator will work for your needs:
