I'm having a hard time deciding between the farenheat 5000 or 7500. My garage is 30x20 with a 9x16 walled off work space. The work space is part of the 30x20 footprint. I would rather buy the 5000 because of the much lower price, but I don't want to be disappointed as well. The garage is insulated except for the door. I live in Michigan and would like to reach 60 when it's in the teens outside.

Electric heat is expensive to run in most areas, and that's not a whole lot of BTUs for the space. If you think it's going to be in the 60s when its in the teens outside, with an uninsulated garage door with excellent thermal conductivity, I think you're going to be surprised.
If you're committed to a 5000 or 7500 watt electric, and there's a substantial price point difference... I would go with the 5000. Reason being, if you think the extra 2500 watts would make a difference, you could easily add two 120v 1500 watt heaters. They're only $10-20 a piece.
The specs on that heater look incorrect... it's showing 5000W, and then 26.1 amps @ 240v, or 6200W. It couldn't have a 1200W fan on it.

I think you read it before I edited, but quoted the correct one.
I accidentally put BTUs not watts. Yes, a 1500W heater is over 5000 BTUs.I have chosen to go electric over gas because of the initial cost of unit and all additional install requirements. I don't plan on heating all the time just when I'm working, maybe a couple if days a month. My electricity is .08kwh so running at full 5000 watts for 8 hours will be less than $4 each day (if my math is correct). At that rate it will take a long time to break even going gas. I am a little concerned now if they will be enough? Based on reviews I have read people having success with spaces bigger than mine with just a 5k. I do plan on insulating my door, it's just not done yet.

I could see the 5K IF you maintain a heated garage at 50F.
Since you want to heat a garage from a potential below freezing tempature, I think the larger unit will get you up to temp faster.
Maybe 2 5K's, one on each side of the space?

Def don't plan on heating all the time but right now it's 28 outside and 43 in the garage with no heat. I thought my door wasn't insulated but now I'm not sure? It's a thermowayne 36 and has a insulated panels sticker on it so I assume there must be some insulation buit in?
