Mr. Heater - Big Buddy Heater it states on box Approved & Designed for Indoor Use --

[New One]

Did a search, many are older 2012, etc never did get an answer.--- are they safe in a tent type fish house with flap partially opened etc.....

The 2016 heater has a max. 18,000 btu output ----- if these are not safe for indoor use, then are there propane heaters other than an electric heater & gasoline generator on the market that are safe for a portable ice fishing house tent.....

Thanks,

Approve by who? Maybe the mfr has a spec sheet (not advertising -sales material) that says who tested it and survived.

Like any fuel-burning heating appliance, it needs fresh air to "breath". Minimum 18 in2 of window or flap opening.

Catalytic heaters are safer than the Buddies, but need a steady flow of oxygen in the shanty as well.

Wave currently makes catalytic heaters, used Coleman heaters are available on Ebay.

I'd say that 95% if it's not higher of the people using portable shelters are Buddy heaters. I have a sunflower Mr. Heater and a Big Buddy for the heat in my shelter. I always keep the vents on the sides open and usually have the door flap open a few inches to a foot or more depending how warm the the outside temp is. These heaters usually pour out an excess of heat so you usually have to open up the door. As more and more people acquire the newer thermo insulated shelters Buddy heaters are becoming the heater of choice. There seems to be enough air leakage into the portables to add enough fresh air even without opening a vent or door. I guess you could asphyxiate yourself, but I've never heard of anyone doing it in a portable. Like anything you have to take precautions.

A insulated hard side fish house could be a different story if the doors and windows are tight and no outside air is allowed in. It seems like every year someone using these shelters dies or is hospitalized because of carbon monoxide caused by a heater not properly installed or with a defect.

When I got my permanent shanty a few years ago, I wanted to experiment with my Buddy heater and carbon monoxide tester.

I plugged the two vent holes in ends of the shack (in the peaks). I put my Buddy heater on high inside with the carbon monoxide detector, and I burned a full 1 lb tank of propane.

I watched the detector through the window and it never registered anything. Tester was at "sleeping level" about 20" off floor.

Shanty is smallish (5' x 9'), and certainly not "airtight" even with the vents sealed off, but I was surprised to see that the detector never registered anything.

I have slept in the shack with the heater on high (connected to 20lb tank) and vents open. Detector has still never registered anything, but I would never use a heater in a permanent without one, but I think they are pretty clean burning units.

Be safe. Alway have a fresh air source when running fish house heaters. Every winter here in the north somebody dies from CO poisoning because there wasn't enough fresh air.

Non vented gas burning heating devices are against building codes in many areas, there's a reason for that.

You can run one of these without problems if you're careful, but you're depending on a cheap sensor to keep you alive, not sure something I feel comfortable doing.

They need make up air or they will start making CO.

I use one when I am in my Clam, but not so sure I'd sleep with one going.

You get to make the choice.
