I heated my whole 1000 sq ft apartment when my heat died ;). This would be hands down the best heater for winter camping provided you have a car battery for it to run on all night (very low current once up and running)The back of the unit for intake needs to be filed out if you want to recirculate air to increase efficiency, also, the fuel line between dosing pump and burner is 5mm inner diameter so it accumulates bubbles at the high point instead of pushing them through; needs to be addressed because an air gap from the cavitation bubbles will cause flameouts which happened a few times with mine, I replaced with the 3mm inner diameter fuel line kit, now i can run 24/7 without issue.
