Abstract
An improved boiler apparatus having multiple resistive heating elements are provided with fixed resistances that can be rewired to allow dual voltage capability and at the same time, reduced watt density. For 120V operation, the large diameter 9-ohm coil is used alone to provide the lowest possible watt density. For 240V operation, all three heating coils are wired in series, creating a low watt density but high wattage heater.
Claims19
An improved boiler apparatus comprising:
- a kettle portion having an interior, an exterior surface, a bottom end having a bottom surface, a top end, and at least one valve fluidly connected to the interior;
- and
- a base portion comprising:
- an enclosure having a receptacle member,
- an insulation member for insulating the interior cavity of the enclosure from the heating element;
- and
- a heating element assembly comprising a coil having a first diameter and a first resistance coupled to the bottom end of the kettle portion and a thermostat;
- a control panel communicatively coupled to a heating coil and thermostat;
- and
- a switch communicatively coupled to the heating coil, wherein the switch is configured to adjust the voltage supplied to the heating element assembly from a first voltage to a second voltage, wherein the heating element portion is coupled to the bottom end of the kettle portion and rotatable around the kettle to provide multiple orientations of the receptacle with respect to the control panel.
