Firewood should be split and stored in a dry place for six months before the heating season begins. Seasoning the wood allows the moisture content to evaporate. Wood that has not dried out well enough to burn efficiently will create smoke-filled fires. Drying the firewood in a radiant-heated garage can significantly reduce the moisture content and drying time. Radiant heating is the process of heating a room through tubing in the floor or panels in the wall. Water is heated and distributed through these panels to warm the space evenly. Green firewood can be seasoned in a radiant-heated garage in 3 to 6 weeks.

  1. 1

    Lay two 2-by-4 strips of lumber on the ground. This will elevate the firewood and increase the drying time. Stack the first row of firewood across the lumber. Make sure to keep this row and all succeeding rows straight and level.

  2. 2

    Lay two 2-by-2 lengths of lumber across your first row of firewood. Position one strip toward the front of the stack and one strip in the back to support the next row of firewood. This will create an air space of two inches between firewood rows and allow air to circulate through the stack. Repeat steps one and two until you have stacked all the remaining firewood.

  3. 3

    Turn on the radiant heating system in the garage. Allow the garage to warm up to at least 18.3 degrees Celsius. Increasing the temperature of the garage will decrease the drying time. The wood will lose moisture through evaporation during the heating process.

  4. 4

    Slap test the wood every three days to determine the moisture content. Dry firewood will make a resounding thud when two pieces are knocked together. If you are moving the firewood to an outdoor location, stack it in the same manner and cover it with a layer of 4-millimeter plastic.

Tips and warnings

  • Remove the bark from wood to increase the drying time and burn efficiency. Bark is a tree's natural protection against fire and drought.
  • Check the wood for pests before stacking it in the garage.
  • Radiant heating raises the temperature of an entire building without the use of circulated air.
  • Stacking firewood like this is also known as strip stacking.
  • Keep flammable material away from dry firewood.
