I didn't really look at the details of the oil radiator. I was just referencing the thermostat, I guess. I smoked out my entire crop by using a heater that didn't cut off when the room was up to temp.Those draw too much wattage though (see above). This one is $40 at home depot.
It only took one night, maybe 6-8 hours and there was no coming back. LoL cooked them buggers good. LoL
