Having just moved into my first home in September, the fear of oil prices through the winter drove me nuts. One thing that my girlfriend and I did was go out and buy this heater from Home Depot. It isn't made of the best material, but for $100, it doesn't need to. This unit will heat 1,000 square feet and in my small, church-converted home, that does enough for our main living area.
One of the best parts of this product for me is the fact that unlike a wood stove, the entire unit doesn't get hot, which makes it safe for kids and dogs. The only part of the heater that gets hot is the bottom section where the heat actually comes from, but unless your child or pet reaches their hand (or paw) beneath the entire heater, they won't be affected.
Another feature I enjoy on this unit is the ability to operate it with or without the heat. In the summer time when you want to add a little ambiance to the room, you can do that without getting hot.
