The NWHS C6 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, and 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 C6.
