Thanks for the heat stick idea, I might have to build one like the ceadercreek website design. The problem with my apartment isn't the power of the stove, I have no doubt I could boil 5-6 gallons along with a heat stick, its the hood over top. I don't know if there's enough clearance for a large kettle to sit on the stove, and still be accessible for stirring and adding grains in a partial mash. I could easily take it off, but I would rather get my damage deposit back instead.
However to go all grain and simply have to boil the wort it might be possible, what size kettle should be used for a regular 5 gallon batch, with the possibility of scaling up to 6 gallon batches, about a 8 gallon kettle?
