A variable power water heater is disclosed. In embodiments, the variable power water heater includes a water tank, a heating element, a power supply circuit, a switch, and a controller. The heating element may be disposed within or coupled to the water tank. The power supply circuit may be configured to generate a power signal for the heating element. The switch may be configured to couple the power supply circuit to the heating element, and the controller may be configured to toggle the switch according to a pulse width modulation (PWM) scheme to control a duty cycle of the power signal transmitted from the power supply circuit to the heating element.

A system and method for continuous level sensing is disclosed. The system employs a continuous level sensing strain gauge measuring a weight of an aircraft waste tank, a lower and upper point level sensors to signal the system as the liquid level reaches each sensor, and a flush counter to correlate with the CLS and the PLS to determine an average flush volume (AFV). Once the AFV is known and updated, the system determines a weighted waste tank level based on a weighted addition of the flush count and the quantity as measured by the CLS. As the aircraft tank reaches a predetermined value, the system alerts a crewmember to the status.
