Systems and methods for powering water heating devices using wireless power transmissions

A point-of-use water heating device configured to be positioned at a hot-water point-of-use, the point-of-use water heating device comprising:

• a heating element;
• a battery connected to the heating element by a wired connection;
• and
• a wireless power receiver configured to:
• generate, based on a magnetic field, an ultrasonic wave, a microwave, a wireless power transmission, or a laser pulse associated with a wireless power transmitter electrically connected to a 110 Volt power receptacle, first electrical current,
• wherein in a first mode based on a demand of the point-of-use water heating device being below a threshold demand, the heating element and the battery are configured to receive the first electrical current from the wireless power receiver, and
• wherein in a second mode based on the demand of the point-of-use water heating device being above the threshold demand, the heating element is configured to receive both the first electrical current from the wireless power receiver and a second electrical current from the battery.

A method for wirelessly charging a point-of-use water heating device positioned at a hot-water point-of-use, the method comprising:

• receiving, by a wireless power transmitter, a first electrical current from a 110 Volt power receptacle;
• generating, using the wireless power transmitter, a magnetic field, an ultrasonic wave, a microwave, a wireless power transmission, or a laser pulse based on the first electrical current;
• detecting, by a wireless power receiver, the magnetic field, the ultrasonic wave, the microwave, the wireless power transmission, or the laser pulse;
• generating, using the wireless power receiver, a second electrical current based on the magnetic field, the ultrasonic wave, the microwave, the wireless power transmission, or the laser pulse;
• receiving, by water heating element of the point-of-use water heating device and a battery positioned at the hot-water point-of-use, in a first mode based on a demand of the point-of-use water heating device being below a threshold demand, the first electrical current from the wireless power receiver;
• and
• receiving, by the water heating element, in a second mode based on the demand of the point-of-use water heating device being above the threshold demand, both the first electrical current from the wireless power receiver and a second electrical current from the battery.
