Style: Industrial
Nice little heater puts out a lot of heat made very well. Price was decent. Not too crazy about the smell.But it puts out some good heat. I like that. It's portable, easy to assemble. Easy to lite. Works pretty good.Has three adjustments for the heat output

    • Very well made!
Style: Industrial
This heater is very well made and heavy duty. Can see it right away and can feel it with the weight and how solid it is. Instructions were good, set up was easy. The very first time you light it does take some time. Similar to a mantle on a lantern. You have to keep the gas realease button pressed, until most of the mantle?/screen? turns bright red. If you release it before that mantle is red, the flame will go out. Mine took several minutes before most of the mantle was red and I could let go of the gas release button and the flame would stay on. Once you have done this the very first time, then you can light it every other time in just a few seconds. Was using this by the Beach in North Carolina in December. Sitting on a deck with chairs all around it about 5 ft away from it. Could feel the heat, but not exactly warm. Ended up having to tilt the head about 45 degrees and pointing it towards the chairs and was much better. Most of the heat seems to radiate from the top. Can feel it from the sides, but the main heat shoots straight up. I think this would really benefit from a reflector plate on the top like those big stand up propane heaters have to push the heat back down and towards the sides. Going to see if I can find a used one somewhere and build my own heat reflector for it. But angling the heater and pointing it works pretty well. Definitely hot, but I think some folks exaggerated a little bit on their reviews of the heat being so intense they had to put on low. But overall, I think this is one of the best heaters you can get. The quality is there and the heat is there based on the BTU output. ... show more

    • Great heater and a time saver.
Style: Industrial
Great heater, warms my two car work shop so much quicker than the wood stove and hassle free. Easy to use, Lights every time and fits under my welding table when not in use. Highly recommend.

    • perfect for my one car garage
Style: Industrial
Easy to connect to a 20 lb propane tank and this thing cranks out the Heat. I had a small diesel heater that I tried to keep my garage warm with while I was out there working but I just never seemed to keep up. This heater on the other hand warms up my garage to t-shirt working weather and short time. I really like the ability to adjust the temperature output with the three position knob. I contemplated buying a torpedo style heater but this takes up a lot less real estate in a smaller garage. Highly recommend for the money quality and heat output ... show more

    • Awesome Heater
Style: Industrial
This thing rocks! I used it the other day in my garage during an extended cold snap of temperatures below 20 degrees and into the negatives with wind chill. Running this in the garage on high and in 30min the 2 car garage was so warm I took my jacket off, was sweating, and had to turn the heater down. This unit is really impressive and provides an excellent source of heat. Would definitely recommend. ... show more

Great for cold day NFL tailgate parties in parking lot. It will flame out occasionally on real windy days. Just need to find a spot to shield it from the wind. Throws off a lot of heat.
