I ran across this surfing the interweb. Interesting and helps to figure costs comparisons of heating. Sent from my iPhone using Tapatalk
I like doing the napkin math on this kind of stuff, it helps price comparing and quantifying what I have. I can also ballpark how much money I didn't have pay the utility company. When comparing don't forget to factor in the efficiency of your stove or boiler. Net and gross are different. You will only actualize a percentage of your wood into usable heat.
Appliance efficiency, and moisture content too. If stove is 80% efficient, and wood is 20% MC, then you have to multiply by .60 to get realized BTU's (basically 20%, twice) If stove is 75% and wood is 18%, it would be .57 (100-25-18)
Or you can do it the easy way (I'm lazy) and use a calculator (there are others, this is just the one I have a saved link to). Already has the BTU's and calculates the cost per million BTU's by price and efficiency for comparison. Hey, and at the bottom of the chart, you can see how much it costs to burn money
Fuel Comparison Calculator for Home Heating | Coalpail.com There are better ones online, too, I just have that link handy.
Just got my propane tank filled. It's used for cooking and backup heat when the family is away from the house. $2.5990/gallon. I used 40.5 gallons last year at a cost of $105.26. based on the OPs chart my wood stove saved me over $1750 this winter. I used a different online calculator and it resulted in $2000 saved by burning wood. I know I bought some chainsaw parts, fuel, oil....but nowhere near $2000. The wood is always free.
