I admit tempting for people that purchase wood, not so tempting for people that have access to free wood. I have not done the math here, but I pay $140 per full cord of wood and burn on average 13 cord a year. That is just over 1,800. In the past with propane cost I would not blink a eye at 1,800. But here is the catch, when I burned propane 4 years ago It cost me $825 per month with the stat set at 58 degrees. With wood I run my house mostly at 68 - 70. If memory serves me right first propane fill was December, January, February, and last fill March. Average fill then was around 800 - 850. Total cost to heat my house at 58 degrees four years ago was 3,300, and was cold and miserable. Only propane appliance was the furnace everything else is electrical. So lets look further, if I was to heat the house to 68 degrees using propane, my costs could have soared to 5,000 or even more. Savings approx 3,200 per year WOW!.. If prices got low enough, never will for this old farm house. The thought of just turning a dial up without dealing with wood .. I would be a trader in a heart beat.
