I am a kitchen-brewer doing 5 gls all-grain batches and am frustrated because the kitchen stove is lacking the last bit of power to yield a nice rolling boil. Are there any indoor-alternatives to the stove?
One thing I did in my apartment was to get a griddle that would cover 2 burners. Put both burners on high, with the griddle on top. Put the brew kettle on the middle of the griddle. You get somewhere around 1.5 the BTUs of 1 burner (some is lost to waste heat, unless you rig up a proper way to hold that heat in, which I never really investigated).
