First of all, don't buy this piece of $hit:
Holmes HCH4050 Ceramic Space Heater
I have it connected to a Ranco controller, and it overheats before it's able to warm all 9 square feet of my brew closet even 2 degrees. When it overheats, it activates this stupid auto-shutoff feature that forces me to switch it off, unplug it, wait 10 minutes, then plug it in again. It's getting returned this week in favor of a better unit.
Anybody have any suggestions for a small space heater that works better? I'd like to use a space heater rather than a fermentation wrap/belt because I want to control the temperature of the entire closet (lagering/conditioning/etc).
