Abstract
The present disclosure relates to systems and methods for connecting to an auxiliary power source and operating a water heater. One exemplary aspect is directed to a water heater configured to heat a volume of water. The water heater can include a first heating system configured to operate at a first power and a second heating system configured to operate at a second power. The second power can be less than the first power. The water heater can further include a first AC connection configured to receive externally supplied AC power at a first voltage and a second AC connection configured to receive externally supplied AC power at a second voltage. The second voltage can be less than the first voltage. The water heater can use only the second heating system when the second AC connection receives the externally supplied AC power at the second voltage.
