I am doing the same project but want to use 120v elements. My proofer is 14 cubic feet interior. 18" wide 26" deep, and 50" tall. I have used two 1000 watt elements in it and only get up to 250 degrees. what size elements should I get to get up to 350 degrees.? I'm using an auber ws 1200 GPH pid on it that is only good for 12 amps. Therefore, I am limited to one element being around 1300 watts and the other I would run straight wide open.one element will get it t
o 150 degrees and the other is undetermined to get the temp I need. Any suggestions? Thanks
