Looking for advice on whether I should get the 50k or 80k heaters for my garage. I have about 1100sqft total and 26ft by 26ft is at 8 1/2 ft ceiling and 20ft by 21ft is at 12ft. I live in mn so it can get cold. Mostly asking if the 80k will be too big and not run long enoug.
Mr heater big Maxx 50000 vs 80000

People are going to ask about your shop's insulation...

MN? I would do the 80k as long as your insulation level is normal for your area.
I heat 1200 sq ft with 10 ft ceilings and open rafters with 80k. I tried a 45k and it just took too long to heat up. 80k is perfect.

also are you pulling your cars in every day ? pulling a cold car in every day does add to the need for a bigger heater,

You could go with either. The 50k would be enough.
50k would produce a move even temp with less hot-spots. The 80k will bring the temp up quickly.
When I faced this same decision I went with the 80k. I normally keep the shop pretty cold until I head out there to work, then I turn up the heat. As such, I wanted to be able to heat the building fairly quickly.
If you get the 80k, I strongly recommend a couple of ceiling fans, especially for the 12' ceiling. They'll help distribute the heat and remove the "hot spots".

Thanks for the info, I plan on keeping the temp down until I want to go out and work. So I'd like to be able to heat up the shop quickly. I'm thinking at least one ceiling fan on the 12ft side especially since the furnace will be on that side. Then have some other fans running to move air around to help with the moisture from the snow and cars
Any tips for locating the ceiling fans?

Nothing more than the obvious:
- Think of the heat pattern from the heater. Fan would be most effective located in the warmest spot.
- Consider clearances, might not want to align a lift with a fan.
- Consider how you plan to use the space. Got cars you need to melt the snow off of, or pull in cold and need to warm up? A workbench you'll be typically located at?

I have a little over 1000 sq ft garage and went with a 75,000 btu. I only heat the garage when I'm going out there to work and I like that I can heat it up quickly. I'm sure it's not as efficient as the 45,000 would be but it's worth it to get it up to temp. I really need to get a thermostat that has a wider range before it kicks back on. I usually heat it up to 70 then shut it off and turn it back on when it gets cold. My dad has the smaller heater in a smaller garage and it takes quite a long time to get up to temp.

I just installed a 50k in a 900 sqft garage, it's overkill with only 9ft ceilings. I had the wife pick it up on sale at farm and fleet, was totally bummed that it is made in China. I'm not impressed by how it sounds when it lights. Wish I had gotten one made in USA for another 100.
