The NWHS e8 is a 120VAC split heat pump water heater. An integrated water pump circulates the heated water to the hot water tank. Super efficient heat pump technology provides hot water while consuming less than half as much energy. Onboard advanced controls provide app-based monitoring and control of the unit, connection via Bluetooth, wifi, and EcoPort. Built-in connectivity allows this unit to be registered with utility companies to provide beneficial demand response services. 900 Watt maximum power draw means a standard, 120-Volt, 15-Amp circuit is suitable to run the e8.
