AquaMotion has been awarded U.S. Patent 11,193,605 for its AMK-ODR Hot Water Recirculation Valve for tankless heaters.
This invention pertains to a hot water recirculation valve that is particularly for tankless On Demand and continuous supply applications. The valve provides sufficient flow to activate a tankless hot water heater when hot water is called for by an end user at a point of use and to maintain hot water at point of use, using the cold-water supply line as the return for the cooling hot water.
The stainless ODR Superflow bypass valve installs under the sink on the cold angle stop by means of compression fitting. It provides sufficient flow to operate the tankless. This product provides instant hot water comfort and can save up to and can save up to 12,000 – 15,000 gallons of treated potable water annually and saves on utility and sewer fees.
The entire kit, AMK-ODR includes a Tee, Valve, and 2-foot hose — UL and NSF Listed, U.S. built in Rhode Island.
The ODR bypass valve is also used in conjunction with the AMH1K-6ODRZT1, (Patent US 10,612,793) Water Delivery System which features a pump with a bypass from hot to the cold inlet line feed to the heater so the heater always sees flow and can turn on instantly when there is demand.
