I bought this last year new. I think I only used it once or twice its practically new. It says on the box 7000-16000 BTUs and that it can heat a 500sq foot area. Looking for $75 OBO.
Edit: I also forgot this was meant to be used with the small lantern sized bottles, but I bought the adapter hose to use it will the regular tanks.
i have a coleman heater like this that i used to use for valet. These things pump out some heat! i lost the line for the bigger tank, so im stuck using the smaller bottles. regardless, GLWS!
