BTU's vs Sq ft Garage heat

Looking at picking up a heater for my new garage.  The garage is 1200 sq ft, I'm getting mixed results when looking at appropriate BTU's is 60,000 enough or should I go 75,000? I would like to keep it around 45-50 in the winter with the option to crank it to 60-65 while I'm working in there...whatcha think?

 Wall thickness?  Insulation?  Insulated overhead doors?

It doesnt take much to keep a well insulated garage around 40 degrees. Where a larger heater comes in handy is when you wanna warm it up to room temp for a few hours so you can work out there. A larger heater will increase the heat a lot faster. Maintaining heat isnt really an issue. You could probably keep it at 40 degrees with a space heater on a thermostat.

 I keep 700sq. ft. (10' sidewalls, also 2x6 and blown in attic) plenty warm with about 34K BTU's.  2 5KW electric heaters opposed in corners with 2 ceiling fans.  The lowest setting on the thermostat will keep it about 58-60 degrees and runs $40-$60/mo in the winter.  FWIW, I don't open the overhead door much though.

as an electrician we size houses at 10 watts per sq ft for electric heat , garages can be adequate with 6-8 depends on your exact wants ,  they make nice 5000 watt hanging heaters 240 volt that are self sustained with fan an on board stats

That's what I've got x2.  Ran them into a contactor so I'm able to run them both off of one thermostat.

I put in a 5000 watt electric heater runs of 220 and keeps the double garage at 45* all winter, if I need to heat it up more I turn it up a few hours before I am going to work in it and it will get it upto a good 60+

I would go with the 75,000 BTU not much more in price and you will notice the difference when you want to heat it up in a hurry.

60K BTU Reznor natural gas is a fine choice.  I would suggest leaving the garage at 45 degrees and just turn it to 60-65 when your ready for projects.  Should run $30-40 per month.

That's what I was thinking...now to find one. Menards in Minot is a cluster *^%$
Went in there to buy one the other day and there system said they had 5 in stock, yet he could not find any of them. I asked if they could order one, he said he couldnt until the system said they had 0...that place makes me want to wash my mouth out with a revolver!

Try looking at the Mr. Heaters at Northern Tool and Equipment, not sure if you get to Fargo much but you can go online and they usually have sales on them.  I've been very happy with mine, very quite and effecient.

1200 sf is a huge garage, that's bigger than most houses.  Don't mess with electric if you have natural gas or propane.  I have a 60K that heats my 600sf garage without hardly any noticeable cost.  I would go at least 75K.  I love mine and am able to turn my garage into a giant walk-in cooler in the winter if I have deer to hang, then crank it up to whatever I want in short order.  Just make sure you get a low temp thermostat.

It will be propane, I might even go to an 80 or 90k just in case. That is if I can find one...finding things in the Minot area has proven to be a tough task...a very tough task.

You can try Grainger or MSCdirect.com if you don't mind ordering one. I've purchased two units in the last few years 150btu and 250btu from a guy out of Cavalier. Each one was purchased and installed for under 3k. He may be able to ship you something. NorthStar Coop, Ron Ritteman, 701-265-4211. If you can't get a hold of him ask for his cell number.

Perhaps your propane supplier could get you something?  Given running on propane my assumption is you're somewhat rural.  Anything available through any sort of rural electric co-op?

I had a hanging Natural gas 110,000 btu in a 26x30 garage. Its kind of like building the garage itself, you will always wish you went bigger. Dont skimp. I could bring my garage from 40 to 85 degrees in a matter of minutes. Great for a man cave,getaway. I done all my reloading and deer processing out there. Plus had a fridge,cable tv,dartboard, and work bench. But BE CAREFUL, soon your significant other will try to take it over as her own. RESIST. Good luck.

It was said once already.  Northern Tool has the Mr. Heater line and they will ship do your door for about a 40% savings over Reznor for the same thing.  Go with the 75K it is $499 and will show up in like 3 days.  My has worked flawlessly for 4 years now.

Holy hell! That's some BTU's!!! My gargage is 30x40 and it will be used as my hang out/cutting/reloading/peace and quite time. No worries about the misses, she hunts too.

 Just bought one yesterday from Acme Electric in Grand Forks.  Heatstar 45,000 BTU for $429.  They also have the Mr. Heater 45,000 at Lowe's here in town for $399.  The two are actually made by the same company and I think they are the exact same product, I just like Acme's customer service.

Now to have it installed, including venting, running a gas line, and thermostat was $600. That was a little more than I thought it was going to be!

I went with this unit, after reading reviews it seemed like the best choice. Ordered the venting, connectors and thermostat. total was 782.71 with shipping and taxes. Thanks to all of you for your help.

im glad someone brought a thread like this back to life.
i have a Fahrenheat brand electric 240V heater in my garage.
it has a dial thermostat on it which is basically low, med, and high with about 3 incruments in between each setting. i would really like to put a programmable thermostat on this thing. it would be nice if i know i need to work in the garage at 7am to have it fire up at lets say 4 am and get up to the temp i desire.

not a big electrical guy. does anybody know how to go about doing this?

OK I know I am just talking to myself here but I finally got the low down on that heater. It is a discontinued prodcut. They have some available down in Georgia. It would cost me $94 in shipping to get it here. Also the 80k has a thermostat and that one doesn't. so long story short I am going to buy the 80k and get happy

It should be a pretty easy 1 for 1 change out.  Just google thermostat change or here's a nice easy link.
