Building a Solar Wood Drying Kiln

It's cold in the Northeast Kingdom of Vermont.  We heat with wood and it's not uncommon for our wood stove to be used 12 months a year.  That means we burn between 9 to 12 cords of wood.  All of our wood comes from our mountain and is processed by Mountain Man.  He's perfected his system.  He's made a special wood cutting station that takes advantage of gravity so he has less lifting to do.  He then stacks the wood into pallets which hold 3/8ths of a cord and can be neatly lifted into our woodshed.

Wood ready for burning 

But there's still one problem. Premium firewood requires 9 months to a year to dry here. And Mountain Man has been thinking about speeding up the process by harnessing solar power. He's looked at lots of solar kilns for sale but they were very expensive and there were none in existence that fit his needs for holding his pallets.  Hence, his prototype for a solar wood drying kiln was born. He worked on his design and then started building it. 

Parts built and ready to assemble.

John, Your set up sounds interesting. Mountain Man says he knows what you mean about accumulating more junk :-) The prototype of our wood drying kiln seems to be working. Snow is deep everywhere yet it's falling right off the kiln. We'll know for sure around Valentine's Day how well it's doing at drying. The good thing about our kiln is it cost us no money to build and would cost someone who didn't have the materials on hand not much money. Once the prototype is up and working, we are moving it to our log splitting station and putting permanent doors on it. Thanks so much for visiting us.

very interesting article on the solar wood dryer. we have big metal barn, one side of it is for firewood only, for stacking and splitting. i can go out cut the wood from our property bring it home split and stack along one side of the barn on the inside. between the sun heating the metal and heating the barn with a really dry heat, i can have cured firewood in a month or so. completly dry and ready to burn. we use about 3 cords of wood a year here in N.E. Arkansas. i probably try the solar method that mountain man uses. it will clear out a lot of space in the barn allowing me to acumulate more junk and store it where the wood was. jcg
