Learning about firewood – Stacking Firewood

admin | July 26th, 2010 | No Comments »

There are many ways to store firewood. These range from simple piles to free-standing stacks, to specialized structures. Usually the goal of storing wood is to keep water away from it and to continue the drying process.

Stacks: The simplest stack is where logs are placed next to and on top of each other, forming a line the width of the logs. The height of the stack can vary, generally depending upon how the ends are constructed. Without constructing ends, the length of the log and length help determine the height of a free-standing stack.

This cover can be a large piece of plywood or an oiled canvas cloth, although cheap plastic sheeting may also be used. Wood will not dry when completely covered. Ideally pallets or scrap wood should be used to raise the wood from the ground, reducing rot and increasing air flow.

There are many ways to create the ends of a stack. In some areas, creating a crib end by alternating pairs of logs helps stabilize the end. A stake or pole placed in the ground is another way to end the pile. A series of stacked logs at the end, each with a cord tied to it and the free end of the cord wrapped to log in the middle of the pile, is another way.

Under a roof: There are no concerns about the wood being subjected to rain, snow or run-off. The methods for stacking depend on the structure and layout desired. Whether split, or in ’rounds’ (flush-cut and unsplit segments of logs), the wood should be stacked lengthwise, which is the most stable and practical method. Again though, if the wood needs further seasoning there should be adequate air flow through the stack.

Storing outdoors: Firewood should be stacked with the bark facing upwards. This allows the water to drain off, and standing frost, ice, or snow to be kept from the wood.

Round stacks can be made many ways. Some are piles of wood with a stacked circular wall around them. Others like the American Holz Hausen are more complicated.

A Holz hausen, or “wood house”, is a circular method of stacking wood which results in accelerated drying and a small footprint. A traditional holz hausen has a 10-foot diameter, stands 10 feet high, and holds about 6 cords of wood. The walls are made of pieces arranged radially, and tilted slightly inward for stability. The inside pieces are stacked on end to form a chimney for air flow. The top pieces are tilted slightly outward to shed rain and are placed bark side up. If constructed correctly, this method of stacking can produce seasoned firewood in as little as three months.
