Systems and methods for a wireless cascading water heating system

A method for controlling a wireless water heating system comprising:

• determining, by a remote controller, a first water heater, a second water heater, and a third water heater, the first water heater comprising a first controller and a first heat exchanger adapted to heat a first supply of water, the second water heater comprising a second controller and a second heat exchanger adapted to heat a second supply of water, and the third water heater comprising a third controller and a third heat exchanger adapted to heat a third supply of water, the first controller in wireless communication with the second controller and the third controller;
• determining a first use value corresponding to the first water heater, a second use value corresponding to the second water heater, and a third use value corresponding to the third water heater;
• determining, by the remote controller, a hierarchical order based on the first use value, the second use value, and the third use value;
• determining, by the remote controller, the first water heater is a lead water heater and the second water heater is a backup water heater;
• sending, by the remote controller, during operation of the first water heater as the lead water heater, first instructions to the first water heater to cause the first water heater to wirelessly send backup information to the second water heater;
• determining demand information indicative of demand for hot water use;
• selecting, by the remote controller, the third water heater based on the hierarchical order;
• and
• sending, by the remote controller, second instructions to the first water heater to cause the first water heater to wirelessly send first operational instructions to the third water heater, the first operational instructions based on the demand information.
