I thought I would revive this thread since Winter is upon us, some of you might get tired of kicking over the portable heaters, I know I did. If you can't do the job, you might be able to hire someone to do it for you.

I decided I would build in a heater, just more convenient.
Got it at Granger's, plywood at Lowe's, Vinyl at Walmart.
I moved the outlet I installed above the vacuum, (off the vacuum circuit) to the left of the vacuum. I pulled a wire from the breaker box to the heater so I could stay on it's own circuit.
I don't worry about leaving the heater on while we are in bed, it has it's own safety's.
