I wanted to go the wood stove in the old fireplace route - to save a buck.
Hubby did some research ... I seem to say that a lot ... and we ended up dropping a little coin and getting a cast iron insert with a blower. It was a little painful at the time ... money wise, but what a long term deal!
This is our third year of heating with it. It puts out so much heat and burns so much less wood than our old non efficient insert, that it is actually saving us quite a bit of money. We have gotten about a cord and a half of wood this year alone for FREE. You don't get prices like that at the utility company! We have ceiling fans and that helps move the heat around the house. It stayed around 70 all over the house (well, the basement and upstairs were a little cooler) and closer to 80 in the living room last winter when temps were 20 degrees outside.
Plus it was great to sit by the fire and toast after being outside or just to read a book. Friends and family were all running around in sweaters and freezing to afford the bills and we sometimes spent the day lounging in shorts with a book! (You do have to fill the wood supply well, before donning the shorts)
I would definitely do it again!
