Large volume hotbox
If any of you guys have any experience with relatively large volume hot boxes, I would appreciate some advice.
The interior dimensions of the box need to be:
48" wide
36" high
18" Deep (front to back)
Exterior dimensions are unimportant, but the inside must be the above or a bit bigger.
The box needs to hold an even 180 degrees Fahrenheit.
Any suggestions as to materials, heating elements and controls?
Thanks.
Tom
