Pro Com heater for me. Got it at Menards for 130.00 bucks when it was onsale, tapped into my dryer gas line on the other side of the garage wall and that was it. It is thermo controled internally so I can set the dial to 1 and it comes off and on when it needs to and keeps the garage 55-60 all winter.

Great unit if you ask me, my neighbors (4) each have one too none have ever failed.

My 2 car garage is heated in about 5 minutes with a small commercial 220volt electric box htr. Its about 14" sq.. you can get one at Home depot or lowes ect. Adj tstat. does a great job. about $100.

 

garage heater?......I just open the door!

 

40,000 BTU natural gas furnace hanging from the 10ft ceiling. Natural gas is so cheap that I can leave my double garage at 65 to 70 deg all winter for less than $20 a month.
Probably the most important item that most folks overlook is a ceiling fan. The air needs to be moving to efficiently heat the garage. My fan gets turned on in November and will not be turned off till late March. It will also dry the floor if you have to park a snow covered vehicle in there.

 

my bbq on high works good for an couple hours

 

I use a two burner Mr. Heater on a 10 gallon propane tank leaving the door slightly ajar. I've been using this for over 20 years without any problems. Mr. Heater = $100, tank = $60 = instant heat, it really helps having your garage insulated. The tank lasts about 3 weeks.

 

I use a butain gas heater, but only when i have the clear space so as not to set the place on fire.

 

+1 on this except mine is propane fired. I too have a 10' ceiling with a high efficiency Modine Hot Dog heater hung from it with althread. Its thermostatically controlled by a Dayton low temp thermostat and works great. The low temp stat allows you turn it down into the thirties or so when it gets deadly cold out to help conserve fuel but keep your chems, paint etc from freezing. Typical house thermostat only goes down to 50. +1 on a ceiling fan going. I have a thermostatically controlled homemade dehumidifier I made from a furnace squirrel cage blower when the furnace went **** up in the house. Converts to a fan in the summer. Makes for a nice workplace all year round. I see your in Michigan so get something dependable.
