Built a wood shed this summer.
Roof is 8' X 48', under roof room is 80" X 47' X roughly 8' high.
Several reason for this design.
Open on all side to allow for air circulation to help dry the splits.
Got tired of tarp covers getting blown away/tore up in the wind.
Snow/ice stuck to the fire wood when bringing into the house.
build-able in 16' sections
Stack the wood off the ground, pallets work great & free & replacable & let air circulate.
If no shed, leave the sides open & just cover the top. (air circulation for drying)
I learned allot about fire wood after I got a new catalytic stove.
Moisture content of the wood is #1 importance:
over 20% moisture & cat stoves don't work well
If wood is much wetter than 20%, most of the energy in the wood is used to evaporate the water & the heat energy goes up the chimney.
Birch cause enough creosote, but wet or green birch is even worse. Dangers of chimney fires.
Birch needs to be split to allow it to dry (Birch bark holds in moisture) even the 4" stuff, split it & use it spring & fall (shoulder season)
Spruce dries quicker than birch, so in a pinch if needed, burn spruce.
Cut your fire wood for next year, this year & let it dry a full year before burning in your stove. Buying wood now for this year, you won't get dry firewood. Buy now for next year. You will get much more heat into the house & less up the chimney if the wood is dry (20% or less moisture content) & allot less or no creosote in the chimney.
I know folks cut wood all winter & burn it right away, but that take at least 2 times a much wood for the same heat as it would if the wood was dry & causes creosote build up & chimney fires.
Wood sellers here say seasoned but typically its closer to "green" wood than dry seasoned around 20% moisture. Ask them to show you that it is. Take one of the splits, split it in half & measure the moisture content in the center. Moisture meters can be found at hardware stores, online etc. Ask for a price break if it's wet, stack it up & use it next year.
Looks good, can set on back deck & look at the stacked/covered firewood
