Mr. Heater Big Maxx Natural Gas Garage/Workshop Heater - 50,000 BTU, LP Conversion Kit, Model# F260550
This is a great little garage heater. It's my second one - the first one has been heating my finishing room for over five years without a single problem so I purchased another one for my garage and we love it. It'll heat up my double stall garage quickly and keep it warm with no issues at all even in the frigid temperatures of this awful winter.

Mr. Heater Big Maxx
Purchased a Mr. Heater Big Maxx several years ago to heat my new workshop operating on propane. The product came undamaged, was installed and has worked excellent ever since. Use it in the winter and heat the workshop when it gets cold and then the weather turns to rain to keep tools from rusting. Could not be happier with the service or the product. Highly recommended.

Good heater until fan breaks
This heater was easy to install and works great. Instruction manual for installation is sufficient that most people should be able to install this on their own. It heats the my 2 car insulated garage pretty well and keeps it comfortable in the dead of winter in Minnesota. It is a little noisy when running but overall works good.
Now for the bad part. The blower fan blade that comes with/on the unit is complete junk. It is made of a very mild/soft steel sheet. It develops stress cracks around the hub between the blades. When this happens it will allow one of the blades to come off of the assembly and become lodged in the cage. When this happens it stops the blower fan from being able to spin and ruins the blower motor. Replacement fan blade costs about $25 and a replacement motor costs about $90. That is if you can find it for sale anywhere. I have found prices for replacements for each but can't find the parts in stock. I have contacted the customer support 4 times in the last four days and can't get a live person on the phone after holding for over an hour. I have sent 3 e mail messages to them from the mr heater company website on the customer support page and no reply to any of those either.
So the moral of this review is, don't leave your heater on at all when you are stepping out of the garage for any length of time because the fan could come apart at any time, costing you over $100 to fix and a lack of customer support to find the replacement parts.

big max garage heater
I've bought and installed tons of heaters and heating systems through the years. For the money the Big Maxx is easy to install, simple to read instructions . A product any do it yourselfer should be able to tackle in a weekend. Other then the gas piping no special skills necessary.buy the optional venting kit and gas hook up kit.

Good but could be better
Bought this heater for my new shop. The output is more than sufficient to heat my 600 sq ft / 13' ceiling garage (well insulated) even on the coldest days (single digits). BUT there are a couple things that they could do much better - both involve noise. The first issue was that the fan that blows the air through the unit. The set screws were not tight and the blade is poorly balanced. After tightening the screws, straightening the blades and removing a little material from one of the blades the unit became better but was still louder than need be. The next vibration was traced to a cheap power vent blower wheel. The wheel was out of round and out of balance. After a bit of bending again and then trial & error placing a small binder clip on the inside if the blower wheel to balance it, the noise was lessened to an acceptable level. None of this was too hard except for the fact that the unit was now hanging 10 feet above the floor - shouldn't have to do this with a new unit. I also have the bigger propane model in another shop and the fan is a little noisy on that one too. Power vent on that one is quieter.

Big Maxx Model# 260420 review and install detail
Overall a great product. I installed it in my garage, hung it from the rafters with threaded rod and unistrut that spanned the rafters. I measured where the threaded 3/8 rod should come through the drywall and dropped them in place. Once I secured those I had someone help me lift it into place from the bottom and we secured it to the rods.
I would not bother with venting kits, I just went to Menards and pieced together all the tubing, adapters, flashing, etc and it was about the same price as the kit and in my opinion the kit is useless.
I hard piped all the black gas pipe directly from the basement to the unit, it was a pain in the rear but well worth it once I was done knowing it was done right. I didn't use any flexible, just a couple unions, one near the unit and the other near where the pipe came from the basement to the garage.
I never vented anything before (cut through the roof) and I found a good tutorial online (video) Ron Hazelton, it really helped. So I watched that and away I went.
I also ran an electrical circuit to the spot near the heater to give it electric. Another pain in the butt but well worth it.
So after I checked all my connections for leaks, I installed a CO detector and fired up the unit per the instructions. It has been running great in my decently insulated garage for a few months now in the Chicago winter.
My only beef with the product was the installation instructions. They really don't give a lot of into on how to connect the flue to this small coupling they provided and then to the exhaust tubing. There are gaps and you come to think it will be leaking CO but after talking to product support they said just hook it up and no worries it will be fine because gas rises and is pulled out. Plus my piece of mind is the CO detector that is not going off, haha!

A Bit Noisy
This unit was not to hard to in stall a bit heavy for 1 person. I am using it in my garage, I attached it directly to the ceiling joist. Started well the first time, heats fast, smelled but that is common, you need to pull the batteries out of the smoke detectors, and no pilot light to waist gas.
Heated well, the only thing I did not like was that it made a lot of noise when it ran, vibration noise.
