I had went to my aunts last winter and it was so hot in their house that I had to go stand on the front porch. I found out that all they have is one of these Duraflame Large Stove Heater, Black, DFS-750-1 to heat their small house and had used only that for 3 years. She said that it did not really affect their power bill and they had not used their natural gas heater in the past 3 years. I saved and saved and finally got us one and it came on Saturday. We got it out of the box and hooked it up! It is very nice looking and great looking when it is on with no heat – Looks like a real fireplace. Turn on the heat and it blows out of the bottom and instantly there was heat coming out of it. I love it and my hubby wants me to save for a 2nd one!! I had seen one at a flea market, but it was a lot smaller. In the above picture , mine is sitting in front of my freezer!
