Well made, effective product.
As my house was damaged in a recent mudslide, I'm living in an insulated shed, and my power system consists of 6 golf cart batteries, an inverter and an inverter generator. I ordered this item so that I could heat the shed without running the generator or inverter. As an electronic technician, I also disassembled it to see what quality it was, and how easy it would be to add a thermostat to it. It's nicely made, has a good quality, quiet fan, and uses a relay to control the heater element, which means less wear and tear on it's control switch, and easy to modify for a thermostat.
It works well, and is quite adequate to get the 8x10 shed comfy when it's low 40s outside. I haven't modified it yet. Draws about 25amps. Heats up in a minute or two, and puts out a pleasant warm breeze. It's running as I type.
Unlike a lot of those cheap window defroster units, it's a solid, well built product that will last, puts out a decent level of heat and doesn't sound like it's about to self-destruct any second like those cheap units. Computer style fan should last for years.. Quite pleased with this product.
