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. Typically, with tankless hot water heaters, the wait time may not be as long but no matter how long, that waiting time is literally washing away gallons of wasted, good, clean water not to mention energy. Simply put, hot water recirculation saves cooled water from being dumped down the drain while waiting for hot water. Hot water cools once you turn off your water. Lukewarm water in the hot pipe is bypassed into the cold supply line. A pump, sensor, switch and bypass valve provide automatic operation so that there is always hot water at the sink.
The AquaMotion AMH2K-R kit is a Hot Water Circulator for tankless hot water heaters that include a dedicated return line. It does not require does not require power or room under any sink. The AMH2K-R installs right into the return line right near the tankless heater. It is a 3-speed circulator with a built-in mechanical timer and Aquastat. All of the moving parts of the AquaMotion AMH3K-7 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!
The 3 speeds offered on the AquaMotion AMH2K-R kit allow this kit to be in large homes with either a storage tank or tankless hot water heaters.
