"This is one great heater, I put in my new 24 x 30 x 10 shop. Heats it up fast. easy to install, and very quiet. Right now I run it on a 20# propane tank until I get it hooked up to a much larger tank. highly recomended. I put a programable t-stat on it with a fan only option on it. works great for moving air without heat on. Way nicer and cleaner than my old wood heater I had."

Mr Heater 75k BTU,
November 13, 2009
By BMoore
from Philadelphia, PA
"I purchased this LP model on line last spring from Northern Tool. It arrived a couple of days, but sat all summer in the warehouse at work. I finally got around to installing it this past week in our shed/work shop. The workshop is roughly 750 sq. ft with 10 foot ceilings. The heater is mounted approximately five feet from an exterior wall, and is centered in the shop. The heater has surpassed all of my expectations. It is remarkably quiet and to my surprise heats the building very uniformly. I was concerned that a heater like this would not heat the building evenly, but those fears were put to rest after 15 minutes of running the unit. I had read several horror stories about these heaters from various forums before I installed mine, and was relieved to find out there was no basis for the complaints. This is without a doubt an excellent heater for the money."

Great Heater,
November 2, 2009
By runningman
from Minnesota
"I purchased this unit to heat my 32 x 32 garage. It has 10 ft ceilings and this unit does the job. My garage is fully insulated and drywalled. I possibly could have gotten by with the 45,000btu unit but didn't want to take any chances of undersizing. I'm very pleased with it."

Great Heater, reasonable price,
November 2, 2009
By coldblooded5
from Seaford, Delaware
"I cannot tell you how happy I am with my new Mr Heater Propane Garage heater. I work out of 3/4ths of a large converted two car garage in which I have an intaglio (hand pulled etchings) studio. Last winter I suffered endlessly trying to heat the place with two large electric heaters. Not any more. Two people were able to easily install my Mr Heater by hanging it from the ceiling. The instructions were clear, access was good, and once up and running it heated almost instantly and was so proficient I had to turn it down. There are no alarming smells and it is reasonably quiet. I don't think you can expect more from a product and I am prepared to be its happy owner for many years to come."

Great heater for the price,
July 20, 2009
By HARVMAN
from central South Dakota
"I had this heater installed and ducted in a couple of hours. It is in a 30 X 70 building that is insulated. I use the building usually one night during the week and all day on Sat and Sun. I keep the thermostat at 45 and even on the coldest days it only takes about 45 minutes to get the building up to 65. I have it hooked to a 500 gallon tank and I ran it from the end of november to around the first of april and used approx. 40 percent of the tank and we had a very cold winter."

I got it working correctly, finally.,

"I've had this heater for over a year. It worked great for a few weeks, then failed to light. I was getting the "two flash light". I flicked power on & off, tried again aand it lit off correctly. Then, a month or two later, it failed again. I checked safeties & traced power. It had blown the low-voltage transformer. I removed & tested it again, yes, the transformer was dead. Luckily, I had a spare in my shop. I hooked that one up (a better transformer with a higher VA rating) & tested the system. Now, so far, it is powering and firing correctly. The heater was fairly easy to hook up. I purchased the flue kit, & ran a t-stat to the other side of the room, next to the enrty door (I can turn it on then entering the bldg). I ran a 120v 20A circuit to a 4x4 box on the wall, & ran flex to the unit. I also ran a gas line in the wall to outside my shop, running to a 120lb tank. My shop is 24X36X9 and insulated fairly good. This heater heats my shop from the low 30's into the 60's within 15 minutes. It really cranks out the heat (and empties my propane). I really would have to caution some about this unit, though maybe mine was just a lemon. I called Mr. Heater, & they sent me a new transformer. I do repairs like this for a living, but maybe others would have difficulty. I really would prefer to not have to repair fairly new items like this."

from St Louis, MO
"I just wanted to say that this heater is fantastic! Easy to install and heats my 30 x 40 garage in no time at all. Very minimal propane usage. The heater is quiet, yet has a super blower to really circulate the air. I will buy another one of these for my next garage!"

Great Shop Heater,

By ST8B

"Easy to install with the vent kit. Small size & little clearance between walls & ceiling make it easy to mount out of the way. Heated up my 2-1/2 car garage in 30 minutes before the insulation was installed, and it was 10 degrees F. Nice & quiet when it is running."

Mr. Heater LP — 75,000 BTU,
March 16, 2009
By Labguy
from Minnesota
"Easy to install, fired right up on a Honeywell programmable thermostat and works great. Might be a bit undersize for my situation (well insulated 30 X 25 shop w 12' ceiling) but it kept the shop at 50o easily even in -20oF Minnesota winter and warms up to 70oF quickly. I did have to put in a ceiling fan to help circulation. Sizing is not a Northern deal though, its on the Mr Heater website, they might be a bit optimistic for the northern states."

"This heater seems to be a good value so far. Only used occasionally on propane fuel in my 3 1/2 car garage. Some times it fails to start on the first try but turning it off and back on will solve that. Easy to install and compact size fits my needs."

Small package, BIG HEAT!,
February 12, 2009
By weendoggy
"I waited long enough and purchased the 75,000btu unit after a lot of comparing. I can say that it does the job and does it well. Hookup was simple once the heater was in place. I did a test fire at floor level with a small tank and it worked flawlessly. I also purchase the themostat which I highly recommend getting.
I have a 24x30 block garage attatched to the house with 12' ceilings exposed. The heater brought the temp from 35° to 65° in about 30min. The fan is very quiet compared to a kerosene floor tube heater. I can still think when its on. Once the directional blades were pointed in a direction that would benefit the work area, it keeps the area warm and doesn't cycle all that much.
The workmanship is very good and instructions were adequate for even the novice home owner. The important part is making sure where you want it and trying to estimate how it will work when installed. If you can do a temporary install to direct air flow, this would be a huge benefit for the final installation.
Another nice feature is the fact you can wire the control to run just the fan in summer months. I plan to do this later this year.
The unit is not too heavy but two people should do the install for safety."

Extremely satisfied,
February 4, 2009
By Deuceowner
from Idaho
"This unit heats my 36 x 40 shop nicely!. I thought that noise might be a factor with a forced air unit, but boy was I wrong. This unit is extremely quiet. The unit is a breeze to install and I was amazed that the unit also is a zero clearance unit. By that I mean it can be mounted directly on a wood surface, or to a surface with 1 inch of clearance from the top of the unit. I purchased the propane unit version and it easily heats my shop from 40 degrees to 60 degrees in about 25 minutes in 28 degree weather. The unit has a 85% efficiency rating. For the money, I don't think it can be beat. Would definetly recommend this product without any reservations."

Mr. Heater 75000 BTU,
January 15, 2009
By laketrout66
from Norther Ontario
"Received unit in good condition. Easy to install on ceiling. Could use better installation instructions for thermostat. Finally located thermostat connection on circuit board after a lengthy search. Once connected the unit heated my garage in about 20-30 mins with - 20 degrees celcius temperature. Garage is 28X32 with 11 foot ceiling. Unit could have used a stronger fan. I have looked at other similiar units but of different make and the fan motor seamed to be stronger. All in all not a bad heater. I have unit hooked up to 500 lb propane tank. Will have to wait and see the longevity of the unit."

Heater nice. Installation was work!,
January 8, 2009
By Toolmaniac
"Ordered the propane model to put up in a Morton Building workshop. Package arrived quickly with minimal damage to outside cardboard box. Nice unit and fairly easy to lift (I am 6' 190 lbs. average jock) but recommend two people to lift in place on ladder or other device.
Things to consider for installation: Installed two joist between trusses in the attic to hang the unit from (time consuming). Venting horizontal is easier but I perfer vertical. Think this process out. This unit requires a 4" exhaust vent. I went through a metal roof and used a Dektite on 4" double wall exhaust pipe. Make sure you have the appropriate tools, fasteners and sealers before starting this part of the project. Hooking the exhaust vent to the unit should be well planned too. It is not easy and you should have the exhaust vent pieces you plan to use to take some rough measurements prior to fit up. I hung the unit using threaded rod on C channel so I could adjust the unit up or down, side to side, and back to front (I used 19" center to center from side to side, could use 20" too). The brackets in the kit require a small amount of grinding to avoid the strain relief on the blower fan and if you use the top 1/2" knockout on the back of the unit for electrical connections. Electrical connections are easy. The unit has two 1/2" knockouts on back for electrical connections. I used 16-3 cord for power and 18-2 (solid) for the thermostat. I have it on a 15 amp circuit breaker. Use a strain relief for the power cord. The gas pipe connection is 1/2" female. I already had propane gas pipe in the shop. I used various elbows, cross, and 1/2" pipe lengths for initial plumbing. A union was used for the final connection. Exhaust vent was connected first and then the gas pipe was fitted. It is easier to make adjustments to the gas pipe than the exhaust venting. A plumb bob is handy during the entire project. Once all connections were checked, the unit powered up, the appropriate green light flashed on the circuit board and the unit fired right up.
The only problem with the heater involved the two top burners were allowing flame to reach and burn the section between the heat tubes. A call to technical support (30 to 45 minute wait on a Monday) stated to pinch the two pieces of metal that form the burner closer together in the area involved which solved the problem. This would not please the average joe. It involved removing 6 screws that hold the panel that the circuit board is on and 4 screws that hold the two burners in place. It took me two times to get it right. I didn't mind as I like to tinker and I have an above average selection of tools.
The unit is quiet for a forced air heater. It works great and heats up my 1800 square foot workshop quickly. It took two weeks of various evenings and weekends at a leisurely pace to get it installed. This review is being written two weeks after installation so no comments on longevity. Good luck!"
