I'm very close to building heat sticks or buying bucket heaters, and then making an insulated boil kettle (just adding insulation to the outside of a stainless steel pot).

Build your own (his waterproofing seems dicey):

Store bought (would need at least 2):

Then I'm out of the kitchen and into the garage!
