This is a mid-efficiency indoor natural gas tankless water heater designed for continuous hot water. Industry-leading low-flow activation with a minimum flow rate of .26GPM and minimum activation flow rate of .40GPM ensures hot water is received even in low-demand situations. Ultra-low NOx burner meets SCAQMD rule requirements of safety with low emissions. While our exclusive Guardian Overheat Film Wrap prevents our units from reaching the dangerous temperatures others can. Add in our maintenance notification settings, self-diagnostic system, and EcoNet-enabled mobile app feature (additional kit available), buying the tankless water heater makes perfect sense. Included are a digital remote control and 10ft. of thermostat wire. Best if used with up to 4 bathrooms; .81-.82UEF (.82EF Canada), 199,000BTU efficiency. Professional installation is required otherwise warranty is void. Warranty: 12-year heat exchanger, 5 yr parts, and 1 yr labor.
