Quick Answer
For a winter in New England, a typical household needs 3-5 cords of firewood, assuming an average stove efficiency of 70% and a moderate-sized house.
Calculating Firewood Needs
Determining the exact amount of firewood needed for a winter in New England depends on several factors, including house size, climate zone, and stove efficiency. A general rule of thumb is to calculate 3-5 cords of firewood per 1,000 square feet of living space. For a moderate-sized house (1,500-2,500 square feet), this translates to 4.5 to 7.5 cords of firewood.
Species BTU and Dryness
The BTU content of firewood varies between species, with hardwoods generally producing more heat than softwoods. Oak, maple, and ash are popular choices for firewood in New England, with average BTU contents of 20-24 million BTU per cord. Moisture content also plays a crucial role in firewood efficiency, with a maximum of 20% moisture content recommended for optimal burning.
Stove Efficiency and Insulation
A well-insulated house with a high-efficiency stove can significantly reduce firewood consumption. Stove efficiency of 70% or higher is recommended, with some modern stoves achieving efficiencies of 80% or more. Proper insulation, including well-sealed windows and doors, can also help reduce heat loss and minimize the need for additional firewood.
