Quick Answer
STACKING FIREWOOD FOR OUTDOOR WOOD BOILERS IS BEST DONE USING A LOG TOWER TECHNIQUE, WITH PIECES OF FIREWOOD ARRANGED IN A PYRAMIDAL SHAPE TO ALLOW FOR EASY ACCESS AND PROPER AIRFLOW BETWEEN EACH LOG. THIS STYLE ALSO HELPS TO PROTECT THE WOOD FROM RAIN AND SNOW. IT'S ALSO WISE TO STORE THE LOG TOWER AWAY FROM DIRECT SUNLIGHT AND WOODPECKERS.
Preparing the Site
When preparing the site for your log tower, consider using a level surface and a slight incline to allow for water to run off. This will prevent the tower from becoming a breeding ground for pests and moisture. A 4x4 or 6x6 wooden frame, 8-10 feet tall, is a good starting point for a log tower, with the base wider than the top to provide stability.
Stacking the Firewood
To create the log tower, start by stacking the largest logs at the base, with the smaller pieces stacked in a pyramid shape above. Leave about 1-2 inches of space between each log to allow for airflow and proper burning. It’s recommended to use logs that are 16-20 inches long, with a diameter of 3-4 inches, to maximize efficiency and minimize waste. Aim for a total of 2-3 cord feet of firewood stored in the tower, depending on the size of your outdoor wood boiler.
Maintenance and Protection
To maintain and protect the log tower, inspect it regularly for signs of pests or moisture damage. Keep the tower at least 3 feet away from any combustible materials, and use a waterproof sealant to protect the wooden frame from the elements. Consider covering the tower with a tarp or mesh screen to prevent woodpeckers and other pests from accessing the firewood. Additionally, keep the tower clear of debris and leaves to ensure proper airflow and burning efficiency.
