    Recently, it dropped to 19 degrees one evening and my son had a football game. Needless to say, it was going to be a long cold couple of hours. I planned to purchase this for a much needed “life saver” moment on the sideline. Bottom line: we were the popular section of the crowd. Great product and easy to use. The 3 settings allows for 30K, 36K and 45K BTUs and can run for 14, 12 and 9 hours respectively. Also, I purchase a gas gauge indicator to indicate when propane tank is low.

    I tried calling Mr. Heater before writing this review but after being on hold for 2.5 hours I give up.

    I’ve owned this for about a month now and used it 4 times. It runs great for about 5-10 minutes then sounds like a jet engine. If you don’t get to the tank and shut it off you’re going to have the bottom of it glowing and catching on fire.

    Doesn’t matter what setting, low, medium, or high and I’ve tried two different tanks. Same problem.

    Apparently there is absolutely ZERO Mr. Heater customer service from 2-5pm on a Tuesday afternoon, so hopefully will take this piece of junk back, and I’ll put my hundred dollars towards something that isn’t a ticking time bomb.

    This was purchased to heat the inside of our garage that is approximately 14’x20′. It only took about 10 minutes to get warmed up; we actually had to turn it to a lower setting as it was getting too warm. What is nice about this tank top is the heat comes from all angles including the top. Our last one had a metal deflector that dispersed the heat just from the sides.

  4. Sasan

    The gas consumption is a little too high even on the low setting. But it generates a lot of heat.

  5. Noah

    Looking for a portable propane heater? This is it. Use it for the patio or with a smaller 10 lbs tank when you head camping, to the range, or when working outside. Easy to setup and efficient.

  6. Monty

    During winter 2020-2021, this unit kept our semi-enclosed patio @ temps of 52-78° which was acceptable as we worked from home.

  7. Pops

    The Mr Heater Tank Top Heater is great: it was easy to assemble, easy to attach to the top of my propane tank, and easy to operate. The instructions are straight forward, and the heater works extremely well. We used it for our Christmas Eve gathering, and the distribution of heat (360 degrees around, 180 degrees vertically) beats my old double-burner “megaphone” heater hands down. I haven’t found anything yet about this heater that I would change. The most difficult task associated with the heater was finding a distributor who still had one in stock; did, and delivery was 3 days earlier than promised.

  8. Fixit

    Warms my garage to 70 deg. When it’s in the 20’s outside in 10 min. On low setting. I love it!!!!

  9. JC

    I was very disappointed. I originally wanted to use it in my garage, but it says it is says for outdoor use only. So, I am using it on the direvway and in my backyard. I found the angle to direct the heat pretty useless, because it is a very limited angle. And, I don’t understand how they can claim 540 degrees, because the heat off the top just rises to the sky. What good is that? Alao, after a few uses it started going out. It seems to stay on for only 10 – 15 minutes before going out.I can relight it each time, but it is a real pain. I am returning it this weekend.

  10. Taylor

    Took less than 5 minutes to un-box, and have it up and running. I have used it a dozen times without an issue. Nice project.

  11. mtw7

    I really like this tank top heater. The build quality is very good and it is easy to set up and use. The only thing I didn’t realize it was missing is a spark igniter. It has everything else you need, including a tip-over safety switch, but you have to find a separate flame or spark source to light it. Not sure why this convenient feature was left out of the design.

  12. Machinehead824

    Bought this for a good size warehouse area thinking we could pick it up a few degrees. This easily brings it to 70 degrees when outside temps are in the 30’s in low mode. Very pleased! Runs 8 hours on low mode.

  13. JoDee

    You won’t be sorry with this heater! Better than the tall patio heaters. BTU and directional adjustments are great! Have not even used it on high yet!

  14. Marti

    This unit has a red fuel button that you push and hold in. But it does not always stay on. When it does stay on, it throws out a lot of heat! However it’s not dependable.

  15. JR

    Works vary good to good had to turn it down from hi to med cuz it was to hot out side at my sons baseball turny in sparks nv and it was in the low 20’s out here i love it money well spent

  16. Heatedup

    I picked this up when the temps were dropping into the negatives. I use it in the garage to keep the chill out since I have rooms above the garage. Works great, easy setup.

  17. Mike

    I thought this would be a good alternative for my bullet heater but it sucks more fuel an the heat isn’t spread out very well.

  18. Roozter

    Purchased this as an addition to the old Mr. Heater directional toppers to provide heat for our tailgate. Lots of people stopped by to warm up, taking photo’s. I replaced my other directional heater the next day.

  19. cgs3

    Heats up garage super fast! I’ll only turn it on high to get it warmed up fast, then even on low it’s almost too warm. Deff good to get the 360 degree warmth….

  20. ebfretz

    I’ve used a half dozen portable propane heaters over the years, this one is the best. Easy two part assembly (just don’t miss the screw packet in the packaging!). Once assembled, just set it on your propane cylinder (any size with a metal collar, 20lb is best and most stable), tighten the securing knob, attach the gas hose, open the main valve, adjust the intensity knob and light it! Has a sort of high-medium-low adjustment, but I mostly leave it on high. You can change the burner angle, which is nice, or leave it vertical which makes it like a nice fire that people can circle around. Two of these in a 20×30 tent will raise the temperature 20-40 degrees depending on how much breeze gets in. 20lb tank pretty much lasts all night. Awesome.

  21. Brandon

    This thing is a bit spooky when running. It hisses pretty loud and the heat coming off of it is immense. I put a fan aimed just above the heat head to disperse the warm air in my garage or else it goes straight to the ceiling. I was going to try to use this camping in a semi enclosed vestibule but I think even on the low setting it’ll do damage to the canvas tent. I’ll just have to stick to the little mr buddy heater for that. If you’re looking for a really nice garage or patio heater this is it.

  22. Anonymous

    Easy to use. Not suitable for indoor areas. I hoped to use this to warm my garage before morning workouts, but I have to partially open the garage to vent the exhaust. It still works after some time, but not as quick as I wanted. It is not recommended for indoor use, but when looking up reviews I noticed most people buy this for larger barn, garage, or warehouse areas.

  23. Anonymous

    Great product. Puts off a ton of heat and beats my torpedo heater since I don’t need electric. Puts off so much heat be careful putting it around things

  24. Razor

    I use it in the basement and it’ll run you out in 10 minutes on low, sure it consumes fuel so choices are keep fuel n be cold or pump that heat out.

  25. thundertiger

    This unit is outstanding! Having said that, please do not use this in an area where the ceiling height is not at least 10 feet up. This unit puts out a huge amount of heat. Read the instructions and Safety Information and always err on the side of caution. Do these things and you are gonna love this unit.
