SmartPlus can save up to 12,000 gallons of water each year and reduce electrical consumption up to 94% when compared to traditional continuous run domestic hot water recirculation pumps. Using state-of-the-art electronics, the SmartPlus will monitor and record the home's hot water usage pattern for the first week (7 days) of operation. For the next 7 days, the SmartPlus repeats the preceding week's usage pattern to cycle the pump, providing instant hot water at all fixtures only when needed. This process will be repeated every 7 days. An optional "Pulse" mode can be selected which sets the SmartPlus to run for 150 seconds every 10 minutes maintaining hot water at all fixtures.
