Average Reviews:
(More customer reviews)I needed to heat an un-insulated 2.5 car garage in the Chicago area, enough to do some wood work over the winter months. I picked this model since it was 50% more powerful than the 5000 watt heater that many reviewed. (I knew from on-line heat calculators that I needed as much heat as I could afford for my set up.)
It requires 8/2 wire, with 240v 40 amp circuit. (It actually uses about 32 amps.) I ran 8/3 (since 8/2 wasn't easily available), and installed a 50 amp outlet & cord. (40 amp outlets are not a common size.)
The unit itself is industrial, as advertised. It is smaller than you might expect for 7500 watts. A few suggestions for improvement:
1. Instructions are poorly illustrated.
2. Instructions state that 10 gauge wire can be used for the supply circuit, but 8 gauge is the proper size. (The wiring diagram inside the unit correctly states 8 gauge.)
3. There are two knock-outs for the power supply cable, one on the back, one on the left. Only one of these two is really large enough for a pre-assembled 50 amp supply cord. This will not be a problem if you are instead running 8/2 or 8/3 directly to the unit.
4. The connection terminals in the unit would be much easier to use if not located in the back corner of the unit.
5. Ability to connect remote thermostat would be nice. (Might be possible; if so, not explained in instructions.)
6. Would be nice to have LED indicating that unit is on.
How does it work? Well, I knew that it would be somewhat undersized for my needs, but I have to say I was underwhelmed when I first turned it on--the heat is noticeable only within a very small area directly in front of the unit. The fan is rated at 2x the CFM of the 5000 watt unit, so I expected the airflow to be noticeable more than 10' from the unit.
To illustrate how far undersized 7500 watts is for my needs, I turned the unit on and left the garage door closed and waited to see how long it would take for the garage to heat up. After two hours the snow finally fell off the two cars. 24 hours later the snow that fell off the cars had not yet melted! There wasn't really a huge amount of snow to melt, and the outdoor temperature during this test was not all that cold (about 25 degrees), so even leaving the unit on for extended periods does very little to heat the garage.
Overall, the unit is as advertised but could use some minor improvements. It is not well-suited for un-insulated garages, but that is not a fault of the unit itself.
