Firewood with High or Very high heat output 1 cord = 21,000,000 - 24,000,000 BTU = 200-250 gal. of fuel oil or 250-300 cu. ft. of natural
gas.
Firewood with Medium heat output 1 cord = 17,000,000 - 20,000,000 BTU = 150-200 gal. of fuel oil or 200-250 cu. ft. of natural gas.
Firewood with Low heat output 1 cord = 12,000,000-17,000,000 BTU = 100-150 gal. of fuel oil or 200-250 cu. ft. of natural gas.
Consider the cost of 1 cord of firewood vs the cost of fuel oil or the cu. ft. of natural gas. The cost of firewood is usually more stable than
the cost of fuel oils or gas and should prove to be a huge savings on your heating bill.
