 Did you know that one cord of firewood provides the heat equivalent to that produced by burning 200 to 250 gallons of heating oil, depending on the type of hardwood you are using?

A cord of Oak will burn about 29 Million BTU’s, and is one of the better (more efficient) types of wood to heat with. Oak is very hard and dense, and will burn for a long time compared with many others.
In case you wondered, a standard cord of wood is 128 cubic feet – 8 feet x 4 feet x 4 feet.
