Constructing a Wood Shed

The drawing to the right details the
construction of an inexpensive wood shed
that will promote drying, increasing the
heat output from your wood.

What Type of Wood is Best

Choosing the kind of firewood to burn in your appliance depends on what is available to you.
Softwoods, such as pine or fir ignite and burn quicker, but require more frequent loadings and are less
suited for overnight burns. For longer burns, with less frequent loadings, we recommend harder woods
such as oak or maple. The chart below details the BTU (heat) output of the various species. Note the
higher BTU output of the harder woods. The best arrangement is to have softwoods for starting and
immediate heating and hardwoods for overnight and sustained burns.

How to Buy Wood

Wood is sold by the cord (4' wide by 4' high by 8' long). Buy wood in the spring and summer, when
prices are lower and it will have plenty of time to dry. If buying in winter, have the wood moisture
tested (test several pieces). You will receive up to 25% more heat from a cord of dry wood than from
wet or green wood. Rotate your wood so as to allow for the maximum drying time for all pieces.
Don't Burn Wood Scraps, Garbage, Paper, Wax Logs, Coal, Etc.
Wood scraps from construction are typically chemically treated, making them difficult to burn and
dangerous due to emitting chemicals. The same holds true for garbage, solvents, driftwood containing
salt, cardboard, and colored paper. Coal and wax impregnated logs burn especially hot, creating a
possible safety hazard. In addition, all the aforementioned items may create excessive creosote.
