This is my master bedroom space heater. It does a great job of heating the 288 square footage of the room. I recommend it, had it 2 years now. Chimney Free Electric Infrared Quartz Fireplace space heater. 5200 BTU, up to 1000 square foot, but I wouldn’t go over 400 sq. ft. Got it from Walmart for $100 on sale but regular price around $130. Has a safety plug, designed to turn off if wall outlet over heats.
