How many calories of energy in a cord of wood? : LUSENET : TimeBomb 2000 (Y2000) : One Thread

I am stockpiling fire wood as a back-up source of fuel for cooking, heating water, etc. It is free here in Miami since Hurricane Irene went through. I have about two cords. Does anyone know on an average, how many calories of energy are in a cord of wood?

"Making the best of basics" talks about kerosene, propane and even newspaper logs, but does not discuss firewood. -- Jose

PS: I realize it varies if it is hardwood or soft, however, I am looking for a general number.

I was told once that the heating ability for 1 pound of wood was relatively constant, the differences come into play with the type of wood and how much wood it takes to make a pound.

What you are actually wanting to know is how many BTU's are in a cord of wood. (BTU = British Thermal Unit) Different types of wood do burn hotter, ie., hedge (Osage Orange) is a hot burning wood.

One of the things we have learned along the 8 years of heating our home with a wood stove is what kind of wood to burn, when.

Depends on whether you eat the bark, and of course whether you dip it in Ranch first.

Here are the BTU values For Wood

BTU Values is an excellent site for all types of heating questions. I have never bought from them, but I have used the site quite a few times for information.

The answer varies according to wood species, moisture content, and what your definition of a cord is. A 'standard' cord (4ft x 4ft x 8ft) will weigh about 3000 lb (@ 10% moisture) and will contain a total heat content of about 17 million btu, which is equivalent to about 110 gallons of heating oil, or 17000 cubic feet of natural gas.

If you order a cord of wood from some backwoods supplier, you will probably not get a standard cord, but a 'running cord', or some other measure. A running cord is 4ft x 8ft, but the depth is equal to whatever length the wood was cut.

Aprox. 7000 BTU per lb. of wood.

How much wood would a woodchuck chuck if a woodchuck could chuck wood?

Burning or chopping (e.g., splitting)? You'll burn up lots in the splitting process.
