If I did it for the money, I wouldn't do it. Can't put a $ figure on the physical & mental benefit gained from a day collecting firewood vs. a day in front of the TV or at my desk in front of the computer.
Three years ago I burned $800 worth of wood to save $300 in natural gas over the winter after factoring in my Home Owners Insurance premium for a wood burner. Now I just sell the wood
All the free wood I want via my arborist friend. Round trip to & back from woodlot is 56 miles. Any jobs that I help him with in town I get as much wood as I want. Typical winter gas bill in my neck of the woods is approx $300-$500 a month.
last winter the largest bill we had was $98.00 & that includes running the water heater on gas.
So the insert paid for itself in 2 years.
That's what I could have sold it for. Do have to admit that when burning wood the house was warmer all day & night than when when I use the gas furnace. It gets set back to 60 degrees at night & when gone to work) so the $300 savings is low if it were an apples to apples comparison.you said $800 worth of wood. is that what it cost you, or is that what the wood was worth if you were selling it?
