I'm relieved to hear this. I'm pleased that you have a sense of humor. My all-electric build is working fine, thank you. An electrician friend certified my set-up before I plugged it in.
Plenty of room. I even added two 120V circuit breakers to the spa panel (very handy), and still had enough room. Of course, I had to drill 4 small holes for the mounting screws.
Too much heat + Heating too small an area (in contact with the wort) = Scorching
It's all about power density, hot spots that make the local wort burn.
You likely don't have 54" because the fittings are in the way. You won't have 18" because there is not that much below the water line unless you have a HUGE grainbill. However, you could use a round one on the bottom too. The round one has re-sparked my interest. I already have a PID...
You're scorching your wort because the watt density is too high in a standard element. Period. To dramatically lower the watt density, use a high wattage ultra-low watt density 240V element on your 120V current. A 4500W element will only draw 1/4 the power with half the voltage. An easy...
