AquaMotion’s Aqua-Shield outdoor circulator is designed for use with outdoor-installed tankless heater recirculation systems. In the southern U.S., tankless heaters are installed outdoors to save on the expensive air intake and exhaust system. The recirculation pump can be installed outdoors and is easily serviced by any installer. The Aqua-Shield is water- and bug-resistant, freeze-protected, and fully automatic with timers and built-in aquastats. This recirculation system provides instant hot water comfort and saves up to 15,000 gallons of water per year. Designed and built in the U.S., the Aqua-Shield is 100% tested and NSF372-approved.
