Hot water recirculation
The SmartPlug will optimize hot water system efficiency and reduce electrical consumption up to 94 percent while saving 12,000 gallons of water per year. The device adds intelligence to standard on/off hot water recirculation (HWR) pumps. Rather than plugging the standard HWR into the wall, plug it into the SmartPlug for improved, house/family-specific function. After 36 hours of inactivity, the device automatically turns off the pump until a need for hot water is detected; in this mode, it also cycles on once every seven days for 10 seconds to prevent corrosion or scale buildup.
