Thanks Guys! We are using K1 currently in our space heaters without much trouble (Smell smoke). It is really a preety nice way to heat the house and sooooo much cheaper than NG. Our house was built in 1895 and when I re-modeled the living room I found scorch marks on the lath under the plaster from gas/oil lamps. Some of them looked like they almost had a house fire.

I am going to check around town before I mail order anything.
