This works great. Heats up my 24 x 24 garage in a hurry. Simple to put together and run. Never had to turn up the heat level. Not necessary. Like I said works great. It does use a lot of propane but besides that it works better than I expected it would for its small size.

This is replacing a 20 year old All Pro 85,000 btu heater. Heats a 30x40 well insulated garage to 60⁰ in less than an hour. Has a glow plug igniter instead of a spark plug. 20 lb tank will last 6-8 hours with dialing down flow or cycling on and off. Easy to light. 10 ft gas hose. Light weight unit.

The heater works as advertised. The garage seems to heat up in 20 minutes. It will be interesting to see how it works in -20 or -30 next winter

I'M USING THIS UNIT TO HEAT UP 800 SQF GARAGE WHEN IT GETS BITTERLY COLD OUTSIDE. JUST TO PREVENT EVENTUAL PIPE FREEZE, AND GET COMFORTABLE IF I HAVE TO DO SOME GARAGE WORK IN THE WINTER OR COLD SEASON. 85000 BTU MAX OUTPUT MAKES 800 SQF ROOM LIVEABLE AFTER 30 MINUTES OF RUN ON LOW. I TESTED IT COUPLE TIME ON MAXIMUM OUTPUT, BUT I REALLY DID NOT HAVE USE FOR IT. I WILL BE MORE PLEASE IF THE UNIT HAS SPARK DEVICE SHUT OFF AFTER IT STARTS BURNING. SECOND ISSUE IS THE JET ENGINE NOISE, WHAT IS TO BE EXPECTED. FOR THE PURPOSE THE UNIT HAS BEEN MADE MR HEATER WILL NOT DISSAPPOINT YOU.

Initially, we didn't think it gave out enough heat, so we called customer service to ask what we could do. There wasn't a great deal the rep could offer, not knowing the technicalities of the product. We visited a local gas operator who advised us to get a connecter hose with a wider aperture which we ordered. Now Mr. Heater works beautifully!!

It worked well to heat the space, but is quite loud.

What I wanted this for was to help heat rooms while remodeling. It is smaller than I expected and I am happy with that and after installing the gas hose and grabbing the extension cord... I had it running in under 5-min.It does put out some serious heat and starts easily every time I have tried. The only two caveats is that in a cold environment you will lose output with cold propane tanks. One day it's max output was easily 30% of normal....all due to the propane tank temp. That would apply to any propane powered heater as well. The other is at full bore, it does suck down a decent amount of fuel per hour. But it all is relative and I understand they physics of it cannot be changed.It is also lightweight and overall perfect for what I needed it for. Some have complained about the loudness of it....for what I deem construction and industrial purposes....it is fine. In a garage, also fine. So yes it does make noise from the fan and flame...but again for it's intention it is great.

This thing puts out some heat! That's what I wanted it for, so that's nice. The unit I got was an Amazon warehouse deal. The cardboard box was a little beat up, but everything was perfect on the inside of the box. Even the user's manual that I still haven't read. This heat is on the louder side though. It's supposed to have "quiet technology" per the sticker on the heater, so I hate it for the folks that had the previous generation of heaters that were even louder. The fans on those must have been engine-driven or something. This heater will go through a 20-lb. (standard sized) propane tank every 6-8 hours with the heater on high. But it's worth it on cold days in the shop until I get a more permanent heating system installed.I haven't found an on-off switch yet so the fan runs constantly when the heater is plugged in. The pigtail is only about 12" long. Kind of a pain to have to use an extension cord no matter where you use this heater. And I guess it's normal for the igniter to run continuously while the unit is plugged in. Mine does.
