Wood Heating Chart | Heat Values of New England Fuel Woods

Have you ever wondered if heating with wood would trim your fuel bills? Look over the information in these charts to help find the answer.

1. Find the kind of wood you will burn from Chart One.
2. Find the kind of wood burner you use from Chart Two or Three. Chart Two is for wood stove users; Chart Three is for fireplace users.
3. Read the figures that apply to your present fuel: oil, lpg, natural gas, electric heat.

Example: If you have a high-efficiency stove, and burn a cord of wood from Group B, and use lpg to heat your home, then Chart Two tells you that for each cord of wood you burn, you save 185 gallons of lpg. You can compare the cost of the cord of wood to the cost of 185 gallons of lpg to see what you are saving in dollars.
