My hope is to have some type of system in place in the next couple of years. However, I do not have a reliable source of cheap/firewood to make the investment cost-effective. My wife laughs at the amount of time I am spending to secure firewood sources, buying equipment, etc. She gets pretty quiet when I ask her to tell me the last time our heating bill went down and when I show her some of the posts on this site that mention how little some of you have spent on fuel oil, natural gas, etc.
