Great Product
This heater is excellent and the perfect fit, for a certain set of requirements.

If you have electricity, use an electric heater. Don't bother with the hassel of propane. The cost isn't too different and the hassel factor is much higher than electricity.

I also don't recommend using the small canisters. That's an inconvinient way to go as well.

BUT. If you don't have power and need a cheap, safe heat source that you can run while you sleep, this is the best one made. Buy the 12' hose, place a 20lb propane tank outside, and run this heater all night with just a small crack in a window or door (just in case!). You will get > 100 hours of heat out of a tank of propane! Less than a buck to run it all night.

Highly recommended under the right circumstances.

Carbon monoxide and propane
I don't (yet) have this heater but it is on my wish list.

I'm posting this merely to point out the inaccuracies and potentially DANGEROUS information in the poster who states that propane does not produce CO (Carbon Monoxide). Visit this site and you'll get plenty of information about this: http://www.carbonmonoxidedeaths.com .

Like all fuels, propane gas requires oxygen to burn completely. Appliance malfunctions, vent system blockage and improper installation will reduce the oxygen supply. When this happens, the fuel will not burn properly, releasing CO into the room, and long term exposure can lead to CO poisoning.

A bigger problem here is that in an enclosed area, the propane heater can consume oxygen. In an oxygen-starved room, the propane will continue to burn, and WILL produce carbon monoxide. This manufacturer was smart enough to include an oxygen sensor to avoid this dangerous situation. In fact, this manufacturer is a FOUNDING MEMBER of a Coalition for Portable Radiant Heater Safety. You will find very few portable heaters that are rated for indoor use today. This is one of them and you should be able to use this safely.

you people are missing the boat on safety!
the main byproducts of propane combustion are carbon DIoxide and water...not carbon MONoxide. You will expire long before your carbon monoxide detector sounds. It's not what this unit produces, it's what it consumes...oxygen. a little ventilation is all that's required to safely operate this unit, and reduce condensation.
Personally I would never use a radiant heater while sleeping, especially in a tent! Radiant heaters heat THINGS, not AIR,if one of those things being exposed to this radiant energy is highly flammable you'll have a serious problem. I have personal knowledge of a radiant heater (albeit a larger AC model) igniting a stack of paper over 3ft away!
a safer, lower cost alternative might be a catalytic heater like the coleman procat... though it has a much lower btu output, it's heating air...not emitting radiant energy. In a large workshop...radiant...in a tent or the like...catalytic.

Save Your Money
I purchased this heater and it was a problem from day one. Out of about one hundred attempts to light, it has only worked three times! The pilot light ignites without problem, but it refuses to work beyond this point. Two out of the three times it worked, it went out when I tried to turn the control from high to low. I have since purchased three butane heaters that work flawlessly. I would not recommend this unit.

Can not handle wind or breeze
I bought this with the hope of using it at our kids outdoor sporting events, but, when ever there was a breeze, the heater would shut off. This heater is a perfect size instead of carrying a large propane tank heater, but could not stand up to the elements. Works great with no wind. If they could just make it wind proof, it would be perfect. ... Read more

EH............ Did you say something?
My heater arrived yesterday. One of the warmer days we've had. But I wanted to use it anyway. It works nicely, BUT IT IS LOUD. My air compressor can not even drown out the noise, but I will get used to it as I do wear ear protection when I operate the machines in my shop. The thermostat controlled shutdown and start-up is a plus. ... Read more
