That's pretty cool.
On colder mornings, my office is freezing. It doesn't get any sun during the day like the living room does, so the thermostat gets to the right temp but I'm still shivering. This will be great on those colder mornings. Also, had a couple of evenings/nights in the uninsulated garage. Will be nice to turn this on and get some heat. Not expecting it to heat the entire garage, but at least make my working space a little more comfortable.
Plus, about ready to start introducing the kids to camping. This will be nice to have if the evening temps drop below comfortable levels.
