I am in the process of building my second oven (first one is too small). I found a great deal on some prefabbed oven panels (measurements 32"Wx9'6"Lx4" thick). I bought enough of them to do a 20' long oven (20x5x6). At $3 per panel, I sure didn't get hurt! What I would like to hear opinions on is this: Would it be wise to build a "BurnBox" and stack 8-3000watt electric elements inside the burnbox and pull air from the oven compartment, across the elements and back out into the oven compartment? I plan to build a "Duct" channel along the top center with holes the entire length to pull air from the top, back into the burnbox (just like conventional batch ovens). The air coming from the burnbox to the oven compartment will go down each side in similar duct channels, mounted lower to the floor. I have access to all the electrical supplies I need, like wire, etc. My main concern is this: Can you control two SSR's with one PID controller? I will likely use two 90A SSR's and split the elements into two groups of four (parallel of course).

I have a 200Amp service in my shop, so that's not an issue. Anybody have any ideas similar to this? I plan to start on the control panel first, and see what else I might run into. Thanks for your time!
