Ron, i don't know the output, it has one fan on switch, and two heater switches, and a rheostat for setting the automatic on/off depending on the temps. But it is only about three inches tall, and i never run it on really hot anyway, just on a low setting, it does fine leting warm air rise up around the engine. Of course, in SC, my garage rarely gets down to freezing. When not using it, i put it in front of the Weimerainer, who sleeps right next to my SPF, guarding it from marauding mice and pesky squirrels and the like.

I don't recall that it was expensive, i got it a a boater's supply place, they use them in small compartments in boats i guess.
