If you are looking to turn your garage or barn into a work space you can use all year-round, you will have to find a safe quiet and reliable heat source. This 50,000 BTU Natural Gas Unit heater is the way to go. It uses a built-in electric high velocity fan to pull cool air into the rear of the heater, across a heat exchanger, then forcing warm air into the surrounding areas. These heaters only require 115v AC power and can be vented vertically or horizontally - please check local codes and restrictions. With a mounting clearance of only 1 inch, the supplied brackets, external access to power, and thermostat connections - installation is a cinch. With the Durable Spark ignition and robust factory standard self-diagnostic control module, we can offer a 3 year factory warranty on all parts and burners and a 10 year warranty on any defects in the heat exchanger. This heater offers the operating versatility and safety that you have come to expect from Mr. Heater.
50,000 BTU per hour heats up to 1250 sq. ft.
Powered exhaust allows for vertical or horizontal venting
Easy outside access to thermostat and A/C terminals and gas connection
Natural Gas to Liquid Propane conversion kit and 2 angle brackets for ceiling mount included
Minimum 8 ft clearance from floor to base of heater required; Limited 3 year warranty on parts and burners and 10 year warranty on any defects in the heat exchanger

Title: 50k BTU review and WiFi thermostat recommendation
Review: Update 2021: starting second winter with the 50k btu unit. After a 4 month summer nap she fired right up. No issues. Super happy with its performance so far. See my original post below for details.Original post 2020: I’m heating a fully insulated 700sqft shop with an insulated 18ft garage door and 9ft ceilings. I installed the 50,000btu unit 2 days ago. Install of the unit itself it easy. I screwed two 48” 2x6 to the ceiling making sure to hit ceiling joists. I was able to hold the heater in place while a friend lag screwed its brackets to the 2x6’s. I’d recommend using a sheetrock lift, it was all I could do to hold it in place. It calls for 1” of top clearance and 36” of rear clearance. It also recommends 8ft clearance from floor. With 9ft ceilings I’m only 2” from 8ft.Obviously running the gas line and roof vent are the hardest parts. I won’t get into that work other than to say be sure you use 4” B-Vent for the roof vent. Do not use single wall vent pipe.It’s very quiet and works well. It’s a little deceiving because it quiet and doesn’t blow very hard but it heats my space quickly. 10 degree rise in about 15-20 minutes. I left it on overnight last night. It was 30 degrees outside. I set thermostat on 58 degrees. It only ran for a total of 1hr and 49 minutes over 12hrs to maintain that temp. And that is total time, including cycle on and off time, burner lit time would be even less. The Wifi thermostat I recommend below tracks run time.I also purchased a Wifi thermostat from Amazon. It’s the Sensi ST55. It’s an easy 3 wire hookup with this heater and allows you to download their app and control the thermostat from your phone. Very handy to be able to kick up the heat from the house before I head out to the shop. It also keeps track of how long the heater runs daily. Nice to know how hard your working it.I’ll update this post with any changes over the next year.Final thoughts. The performance of any heater is dependent on not only the size of the space you are heating but the condition of the space; insulation, draft, if there’s a ceiling or not, etc. The 50k btu unit works great in my space (as stated in my first paragraph).Hope this helps others with their decision.

Title: Four years running still no issues
Review: Update Feb 9. 2024Still going strong. Absolutely NO issues..Update: October 17, 2023I flipped the heater on today after leaving it off since sometime in April.. Its been in the low 50's so I just wanted to take the chill out of the garage and sort out my tools for a fall project.The unit fired right up, warmed up the garage, no issues, just did its job. This unit has been very reliable for me, and I continue to recommend this heater for a garage.-------------------------------------------I bought this heater in September of 2019 when I retired. I live in western NY where the winters are long, dark and cold. Since the wife doesn't want to snowbird in the south, I figured I better heat the garage, so I had a place work on projects.If you can run some natural gas lines and stick a vent through the roof, you will love this heater. I stuck a cheap thermostat on it from one of the big box stores, a separate house switch on it to flip it off for the summer months.I have had NO problems with it. It runs for 6 months during the cold months, then I flip it off at the end of April, when October comes, I flip it back on and it fires right up. It doesn't make any vibrating noise like some have said, vents out the garage roof using the double wall vent duct with a hat to keep the snow out. I insulated my garage walls and ceiling with standard R19 from HD, and drywalled it as well. My garage is 24' x 24' x 10' with concrete floor. This unit heats it with no problem. I should have installed one years ago.Also, I did not use an isolation relay to isolate the unit that protects the house wiring from "a pulse" from the unit when the solenoid kicks on and I have experienced no issues with the unit interfering with the house electric. I have broadband internet, smart switches, smart lights, Alexa, etc.. and have experienced no issues.If you're like me, live in the north and have some DIY skills and are sitting on the fence, just pull the trigger and buy it. You'll get a whole new play area for the winter months. 🙂

Title: Puts out the heat and reasonably easy to install.
Review: I put this in my hunting cabin for really cold nights less than 25° and it does a great job. It’s a little noisy, especially in a small cabin but little noise versus cold in the morning when you try to get up to go deer hunting is a little bit of a no-brainer.

Review: Had the unit professionally installed in a new workshop space. Went in without problems, worked when first fired up, and ever since. Puts out a lot of heat in a short time, but without scorching its mounting or surrounds.

Review: Became intermittently noisy after about 3 days in operation and very noisy after about a week. Mr.Heater wasn’t much help. Amazon replaced it on the 29th day. New heater was shipped to me but without prepaid return shipping. I had to pay return shipping but was credited the shipping cost onto my account. New heater has been working great since the install. Very quiet. Heats my 24x26 garage nicely. I did find the exact same heater in town on sale for $100 less with a regular price equal to Amazon. Do your homework and check locally first.Edit: September 4/19. Tried to start heater to test for the upcoming season and nothing. Verified 120acv and thermostat to be ok. Will attempt to contact Mr.Heater to resolve this issue.
