1. A liquid heating appliance for making a beverage, the liquid heating appliance comprising:
a plurality of heating components, where at least a first of the plurality of heating components is powered using mains power,
a power management system, wherein the power management system comprises:
a controller, and
an energy storage device,
wherein the controller is arranged to:
control an amount of the mains power applied to the first of the plurality of heating components,
control an amount of stored power from the energy storage device to be applied to at least a second of the plurality of heating components, and
switch polarity of the voltage of the stored power from the energy storage device to be applied to the second of the plurality of heating components after one or more heating cycles associated with the second of the plurality of heating components,
where the controller is arranged to switch polarity of the voltage of the stored power from the energy storage device by controlling a duty cycle of switching devices arranged to switch the polarity of the voltage of the stored power.
