Kettle apparatus and method thereof

Abstract

An improved boiler apparatus having a removably couplable heating element that can have resistive heating elements are provided with fixed resistances that can be rewired to allow variable wattage usage of the heating element. Some heating element assemblies can include more than one heating coils or heating element. The heating elements can be wired in series, or parallel thereby creating a low watt density but high wattage heater.

What is claimed is: 
     
         1 . A kettle apparatus comprising:
 a kettle portion having an interior, an exterior surface, a bottom end having an interior bottom surface, an exterior bottom surface, and a top end;   at least one aperture configured to allow a liquid flow between the interior and exterior of the kettle portion; and   a removably couplable heating element assembly comprising a first heating element having a first resistance, wherein the heating element assembly is coupled to the bottom surface of the kettle portion.   
     
     
         2 . The kettle apparatus of  claim 1 , further comprising:
 a housing member configured to house a portion of the bottom surface of the kettle portion and the heating element.   
     
     
         3 . The kettle apparatus of  claim 2 , wherein the housing member further comprises an inlet portion. 
     
     
         4 . The kettle apparatus of  claim 3 , wherein the housing member further includes an insulation member for insulating the interior cavity of the enclosure from the heating element. 
     
     
         5 . The kettle apparatus of  claim 4 , further comprising at least one fitting member fluidly connected to the aperture. 
     
     
         6 . The kettle apparatus of  claim 5 , wherein the housing member includes an electrical connection port communicatively coupled to the heating element assembly and a sealing member configured to form a seal between the bottom end of the kettle portion and a top edge of the housing member. 
     
     
         7 . The kettle apparatus of  claim 6 , further comprising:
 a controller communicatively coupled to an electrical connection port, wherein the heating element assembly further comprises a second heating element having a second resistance.   
     
     
         8 . The kettle apparatus of  claim 7 , wherein the second resistance is greater than the first resistance. 
     
     
         9 . The kettle apparatus of  claim 8 , wherein the heating element assembly further comprises a third heating element having and a third resistance. 
     
     
         10 . The kettle apparatus of  claim 9 , wherein the third resistance is the same as the second resistance. 
     
     
         11 . The kettle apparatus of  claim 7 , wherein housing member further includes a removable access panel to access the space within the housing when the kettle portion is resting on the housing member. 
     
     
         12 . The kettle apparatus of  claim 1 , wherein a thermal conductive layer can be provided between the bottom surface of the kettle and the removably couplable heating element assembly. 
     
     
         13 . The kettle apparatus of  claim 14 , wherein the conductive layer can include at least one of the following: thermal transfer paste or one or more conductive pads. 
     
     
         14 . The kettle apparatus of  claim 15 , wherein the heating element portion is coupled to the bottom of the kettle portion using one or more fasteners. 
     
     
         15 . The kettle apparatus of  claim 16 , wherein the heating element is removably bonded to the bottom surface of the kettle portion using a high temperature thermal adhesive. 
     
     
         16 . The kettle apparatus of  claim 11 , wherein the heating element is removably couplable to the bottom surface of the kettle portion. 
     
     
         17 . The kettle apparatus of  claim 14 , wherein the heating element assembly is bonded to a subplate, wherein the subplate is removably couplable to the bottom surface of the kettle. 
     
     
         18 . The kettle apparatus of  claim 17 , wherein the housing member further includes a removable access panel into the interior area beneath the kettle. 
     
     
         19 . A kettle apparatus comprising:
 a kettle portion having an interior, an exterior surface, a bottom end having an interior bottom surface, an exterior bottom surface, and a top end;   at least one aperture configured to allow a liquid flow between the interior and exterior of the kettle portion;   a housing member configured to house a portion of the bottom surface of the kettle portion; and   a removably couplable heating element assembly comprising a first heating element having a first resistance, wherein the heating element assembly is coupled to at least one of the following:
 the bottom surface of the kettle portion or the housing member. 
   
     
     
         20 . The kettle apparatus of  claim 19 , further comprising a controller communicatively coupled to the heating element assembly.
