I am wanting to convert my 10 gallon kettle into a stove assisted ekettle. I dont want anything fancy with PID just a simple plug in and brew. My kitchen has 1 20amp circuit with a 15amp plug. I live in an appartment which is very old but well kept and I am not sure what condition the wiring is in. Because of these factors should I stick to 1500W max or can I move up to something higher such as 1650-2000? I would like to stick with a 120V element to save on size as i use a false bottom with 3 legs and a big rippled element might cause a problem. Also, some elements i look at are made with SS some are zinc coated. Does this matter? Any adivce would be much appreciated.
