I'm glad you mentioned this. My plan was to rely on the heaters tstat. I never would have thought of a space heater tstat failing wide open. But it makes perfect sense.
When running the heater through a thermostat is there somewhere specific you put the tstat probe? I would imagine since it's used for ambient temps it can go just about anywhere? Except obviously right in front of the heat source, of course.
Thanks, Deb!
