I used to use an electric kiln to do firings for my partner. It was fun working on the process. Our house had a lowish supply voltage so I ran 10mm2 cable back to the consumer unit, and experimented with the impedance of the elements, as we did a lot of quite high firings. I used an electronic kiln controller mostly but occasionally verified it against an Orton cone. Gas would have been more economical but a bit more scary, for me anyway.
