In 02 I built a new house, this is in the mountains of Calif. just outside Yosemite so it does get cold there. I installed forced air but LPG was around $3.29 a gallon so you don't want to be running that too much. I installed a nice pellet stove, that thing works wonders on keeping down your gas bills and heated all of the front half of the house. The pellets are a lot cheaper then gas!!
I used my old house as a shop after I got the new place built and it too has forced air but I heated with the air tight wood stove. Wood cost me nothing because I had to cut, clear and trim anyway. A good air tight is a true joy and easy to operate.

And yes, that's as good of a Vanna as I can do!!
