Pitch

Solar powered wood drying reduce the moisture content of wood in half the normal time.


Description

Summary

A solar firewood dryer will cut the wood drying time in half and the wood you cut and split in late summer or early fall should be ready to use later in the winter. The fully seasoned wood will burn cleaner with less creosote and smoke and also burn more efficiently. The solar firewood dryer can be built by anyone in an afternoon.

The dryer’s slanted roof ideally should be set-up toward the south. Due south is best, but 25 degrees west or east of due south will also work. The right exposure lets the wood receive the maximum amount of the sun’s heat to speed up the drying process. It is important to split the logs to speed drying before putting them in the dryer and to keep the wood off the ground with bricks, concrete blocks, pallets, 2×4’s, fence posts, etc. Stacking the wood in a criss-cross pattern also facilitates drying.

Before the pesky winter rain and snow come, make sure the plastic sheeting has no rips or tears that allow the wood to get wet as well as wood is dry when it is showing cracks or splits to the center of the piece.
