The energy used to heat your house is measured in BTU’s (British Thermal Units). The size of your furnace is measured in heating BTU’s
it can provide; for example a common furnace size is 50,000 BTU’s.

Table Notes

*The above calculations are based upon average operating furnace efficiencies that occur during a typical heating season.

*Wood is factored at burning for 6 months / year ( Oct – Mar) @ 15 min per day – load time @ $14.00 per hour , using 150 mbtu per year
@$390.00 / 6 cord total cost for year $960.00. $300.00 is equivalent of what selling wood would yield.
