Hello John, this heater should not be used to heat a room to that degree. Attempting to do so will pose a safety hazard. This heater is designed for heating space to comfortable temperatures for the average person. - GHP Group Customer Support

Had mine shipped to the Home Depot store in about 2-3 days, they infoed me when it was on the way and when it came in.
No, had to order it and it only took a couple days.
It has a thermostat, just set it and stand back. I've had it near 80 for a test, too hot for me.
