“I gave this four stars only because the product description is a bit misleading. As printed on the box, the heater has high (1500w), low (750w) and fan only settings. The fact is the heater has one fan speed and two heat settings. In other words, the fan speed remains the same regardless of which heat setting you have it set on. Besides that, this thing heats my standard two car garage on the low heat setting and keeps my dogs warm when the temps outside are in the 30's. I would definitely buy it again.”
“May work in a very very small space. I have a. small two car attached garage that is well insulated and sealed. I haven't noticed much difference in temperature after four hours.”
