Liquid Fuel Tent Heater

[adrenaline503]

Units that claim to be safe for indoors should have sufficiently complete combustion that carbon monoxide production shouldn't be a problem. They still consume oxygen and produce CO2 so shouldn't be used in closed spaces. Instructions may state how big of a vent space (e.g. open window) is needed - maybe 6 square inches. Instructions probably also tell you to keep flamables several feet away on all sides.

Gotcha. Thanks for the info.

Also keep in mind that one of combustion's by-products is water. The better (cleaner) it burns the more moisture produced.
A friend had one of the Coleman units in his 4rnnr and in the morning had both a wet bag and stalactites on his windows.

I'm not completely comfortable with the idea of burning anything on a tent while I'm sleeping but I have a friend who uses the Coleman units in his moose stand (an insulated affair that they enter the evening before and sleep in in very cold weather) He says they simply need a window to be cracked for combustion air.

I am a big Webasto fan. I've had one on every diesel Cruiser of mine for many years now and had a Pro Heat before that. They keep the truck nice and warm if you are sleeping inside. Now that I'm sleeping on the roof, I'm trying to decide between a separate air top unit for the tent or just running a heater core and coolant lines up there.

R.E.Byrd's (Alone) stuggle with a faulty heater in an Antarctic base is the classic tale of carbon monoxide poisoning.
