The ClassicFlame® Infrared Quartz Electric Stove Heater heats an area surprisingly fast. I love the ambiance that it creates. It has a fire-like glow to it. The infrared quartz elements are 5,200 BTU. It heats up to 1,000 square feet. It takes minimal assembly. The only tool needed is a screwdriver. It is pretty self-explanatory. It does come with all the necessary, important instructions and safety warnings. I love that I have to option to have the heat on or off while the flames still glow and flicker. It is easy to operate and creates a very homey feel.
