I have a 50 x 50 basement that is insulated. With no heat on it stays around 55 deg, installed a propane fireplace with built in thermostat that will put out 25,000 btu. Also have a ceiling fan. I turn both on, shut the door and within 30 - 40 mins the place is sizziling warm. The best thing is you don't need to vent it to the outside, all the heat goes into the room so nothing is wasted. I use a 100lb tank to feed it which I just filled up yesterday for $67.15. I only use it on the weekends in the winter and the tank lasted one year. Plus its nice to look at, I have a corner model.
