Heres the problem. I should be more specific. We do have a complete heating system that works great its reliant however it is our last one and its much to heavy to carry into the space we need to get to without getting it rigged in and out. we need something semi portable like the old power cons there heavy but nothing compared to the alternative. I need for it to regulate its power to hold at temperature so something like useing a thermal couple would be fine, but its not necessary for it to record that would be more of a luxury. Thanks for the responses their more than what I've been able to find.

The Miller induction heating unit is the way to go if portability is the primary goal. Here's a link to the Red-D-Arc website if you want to rent one to try it out before buying:
