Would it be possible to install an electric hot water heating element through the side of my brew kettle? I have a slightly under-powered propane burner, but I'd like to avoid all the sealing issues associated with a heatstick. Could I install the element through the kettle wall, similar to the way it is installed in a water heater? Then the waterproof seal would be on the inner wall of the kettle, with the electrical connections on the outside. It would be nice to have a short pigtail electrical cord to plug/unplug so I can wash the kettle.
