Systems and methods for preventing and removing chemical deposits in a fluid heating device

A fluid heating device comprising:

• a fluid chamber in thermal communication with a heat source;
• a plurality of ultrasonic transducers, at least one of which is configured to transmit ultrasonic waves into a liquid in the fluid chamber;
• and
• a controller in electrical communication with the plurality of ultrasonic transducers, wherein the controller is configured to:
• receive temperature data from one or more temperature sensors;
• determine, based at least in part on the temperature data, whether the heating element is engaged;
• and
• activate the plurality of ultrasonic transducers in response to fluid flow through the fluid chamber and in response to determining that the heating element has disengaged to reduce or prevent contaminant particles adhering to the fluid chamber.

A method for ultrasonic cleaning within a fluid heating device, the method comprising:

• receiving, at a controller, flow data from a flow sensor;
• determining, by the controller and based at least on the flow data, whether fluid is flowing through a heating chamber of the fluid heating device;
• determining, by the controller, that a heating element is disengaged;
• and
• activating, by the controller, in response to determining that the heating element is disengaged, one or more ultrasonic transducers to reduce or prevent contaminant particles from adhering to the fluid chamber.
