My 2 home depot electric space heaters currently heat my 2 story farm house a lot cheaper than the fuel oil furnace I have. I don't even run it anymore. It was like $1500 to fill a tank and a half. It's about an extra $100 a month during the winter months on my electric bill so my "heating" expenses are about $500 for the year. We'll see if this Heat Smart heater lessons the bill even more. This is the one i've had for about 4 years. Only problem is if the power goes off you have to turn it back on and reset.
