It seems like its a double edged sword so to speak. Wood has its negatives for sure, I get my wood delivered by the whole semi load and when that gets too expensive, our state/county has a program where we can get up to 6 cord a year free if we go do the work. When I buy semi load fulls of wood, its 20 cord plus loads that last me 5 to 6 years. The heat pump system, like you said, is crazy expensive but the electric costs are low, for now??? what about the projected costs when everyone is using electric vehicles, electric furnaces, electric dryers, and all sorts of electric appliances....electricity is sure to rise. Then you become dependent on just one energy source with no backup. That might work in your area but here in the Yoop where it gets mighty cold in the interior...I can't do that. We have plenty of wood, its a renewable resource here. My other house I built was less insulated, larger, 1700 sq' and that too I built my own wood boiler in addition to the propane boiler to lessen the cost, in that house, I averaged 5 cord a yr INCLUDING domestic hot water (system already had an indirect fired water heater). Cost to run the circulator pumps was about 10 bucks a month. Some systems work good in some areas. Im just worried about the future, electric where my new retirement home is, is still higher than most of the other places in the Yoop, out there its UPPCO, thats why I tried to limit how much electricity I would use. Glad your system works for you tho'. Its nice to share ideas.
