Comfort Glow propane heater. Very nice propane heater I used during power outages, and it kept my house away from freezing temps. I primarily used it for working on cars, just set it next to me and it brought some warmth on the coldest days. Only 2 chips, but I did while removing the front chrome grill while cleaning it up so I could use it. Unit can be mounted to the wall will slots for easy mounting or free standing as it is shown since it has feet to stand on its own. We also used it while camping but recently switched to a propane fire pit. Can be mounted on a wall and does have all the safety devices like a low oxygen sensor. Adjustable from 5k-16.5k BTU for heat settings and can be attached to any size propane tank since it comes with the supply line hose and regulator. 20 inches wide, 24 inches tall and 8 inches thick at the bottom and tapered at the top of the unit.
