The term you were looking for when drying wood too fast so that it is dry on the outside and wet on the inside is called case hardening. Love the video! Very informative. Keep up the great work!
Thank you. And yeah I just blanked out at that point. Haha
hi there we built one years ago to run off his boiler around 10 years ago . 8 small fans , made from almost all trashed parts . jeff built a computer that knows the wet bulb dry bulb ratio to turn the exhaust fan on and off . i really dont know much about it , he drys cabinet wood and has different schedules.for different wood , and it does make his boiler eat wood , well done john
Yeah it’s really a science. But if it works it works. Cabinetry and lumber is a unique drying system. Not sure I would ever try and dry a slab. Maybe one day.
I would have to say that is the best kiln video you have put out to date. The difference between green and seasoned wood was excellent information. I was shocked at how little it cost to build. That is a great return for the investment. I will be very interested in your probes when you get them installed. Have a wonderful day. Thank you for the excellent content.
Thank you. Yes didn’t cost much. Just my time to put all together and the research I taken to figure out how I wanted to run the kiln. But all worth it. I may get the probe system shortly. Once I have that I can really dial the kiln in
Just wanted to say thank you for the well-produced channel in the excellent content
Thank you. I try and give out any info I have to give. Much appreciated.
I just found your channel and subbed. This is the best kiln build I've seen. Nice explanation on how you use it. I'll go back and check out the build videos.
Thanks for coming a long. I’ve put a lot of time and research into the build and have made a lot of adjustments. So so far so good. I’m sure there is room for improvements down the road.
Great job explaining your process. Good luck!
Thank you.
Man I have been experimenting with some small kilns and looked through the entire channel yesterday looking for a build/review could find bits and pieces but this is great.
Glad I finally made one. I actually just totally forgot to make one. Time flies I guess. Hope this one helps.
Great job! Have watched all of your videos though out the build glad it is working how you envisioned it!
Sometimes it’s pretty nice to stand back and look at what you built. Especially when it works.
Very interesting with all the details you mentioned, helps alot! Im looking forward doing the same setup. Thx from Sweden 😊👍
Awesome. Hope I gave you lots of great info. Good luck on your build.
This is great! Yes i believe you are the first to put this on youtube. I have built a solar kiln and ive been designing a stick build wood kiln and want to use my Central boiler. I think this is a great setup, well done!
Thank you. What are you drying in your kiln?
Nope, oak farm firewood has some great videos about this subject as well 😁
@markassink8552 yes he does and he’s a buddy of mine.
Great video. The review is Awsome. I Would be really excited to start a kiln build using my outside wood boiler. I’m currently trying to finish up a homemade processing station. It’s close to being done for now. Like you said down the road, look to make more improvements. Working and tinkering takes time. Have a great day.
Hope my build really helps with yours down the road. Stock up on firewood. You will need it.
Great job explaining the entire process! Costs, time etc. you really did a great job with your kiln and it’s done right! 👌🏻 I’m still brainstorming, but my biggest downfall is not having a boiler so I’m looking at other heat sources
I am also looking into some type of solar with some type of electric heating element as well. We will see what I come up with.
I am thinking of doing the same thing, but use a used oil furnace to burn up my used oil from my business. I like this setup.
That would be a great way to use up some used oil.
I have a 8x16’x7’ high wood shed. I burn 5 cords a year and it holds almost 6 cord. I always wanted a kiln but for the money and small amount of wood I burn isn’t feasible. I’ve been experimenting wrapping it in 5 mil clear plastic. The westerly side I leave a 2’ opening on the bottom, easterly side I leave a 2’ opening at the top. That’s how we natural ventilate homes in smoke conditions in the fire service without a fan. Winds are mostly west/ southwest. My temp gauge/indoor outdoor thermostat reads 120/130 at highest temps during the daytime afternoon sunny days believe it or not the fresh split oak, maple, locust, that was split in April/May has moisture readings between 15/19% in late October. I do split the oak and locust in 2” plank like pieces to dry faster. I would love a kiln, great videos and great work explaining your process. Keep these interesting videos coming.
Sounds like you have a great set up. I will definitely try to keep it up.
I have been cutting 20 cord a month and need to start considering kiln drying. Will definitely need to be wood heat boiler.
20 cord a month is a nice number.
Love it. I've been planning something similar for the last couple years. Just need to get going. I think only thing i had in mind was on the venting to create a heat exchanger where dry air is coming in and gets heated by the exiting hot air.
Curious of why you run the dehumidifier to finish off seasoned wood vs just using the boiler?
Love the setup.
When I run the dehu I can get the wood crispy dry. If that makes sense. When I run it and open the doors you can feel how dry it is in there vs just heating the kiln from the boiler. I feel the product is then a premium.
Thank you for this! A lot of great info.
Do you think that loosely stacked totes would dry faster?
I don’t think it would dry any faster at all because of the airflow would be interrupted and not flow through the wood. So some moisture could get blocked. Could be wrong but it’s like a wind tunnel. You put a void in there and it messes up the stream line.
My buddy and I thought about using the ground as a condenser so the energy consumption would be from fans moving the air through a perforated pipe in a stone bed under ground with proper drainage?
Like bare ground or have gravel inside of something so the water would drain? If it’s on bare ground you will never get rid of the moisture.
What if you placed a 20” fan on the front of the tote of fresh cut wood to help lower moisture content?
You could do that but I feel you would dry the wood to fast and it would case harden and lock the moisture inside and not dry efficiently. I could be wrong but the way I have mine set up works great.
Jack firewood Turner maine, outdoor 40 ft. Boxes uses wood furnace
I’ll have to check him out.
A guy from England has a U-tube channel and uses a boiler.(very sophisticated)...
Oak farm? Yeah he’s a buddy of mine.
Great video, why wouldn’t you take the exhaust fan I. The front of the kiln and redirect it inside the shop instead of outside.
I don’t want all that moisture going into the building. Mold would start and it would just be a bad day. Way too much moisture inside the building if I would do that.
Respectfully, You cover the cost of building this unit. I would like to ask you what you charge for a face cord of wood that is dried? You pick the species of wood. Thank you.
I sell a facecord of mixed hardwood of kiln dried wood for $150
What temps are the exhaust vs the intake air?, I'm assuming the intake is ether outdoor temp, or house/shop temp.
Some air to water heat exchangers(2 in series the exhaust, 1 in the intake, you capturing from the exhaust so you ether have slower flow over the exhaust exchanger or more surface area to maximize heat capture) and a separate circulation pump + piping, gets you a DIY heat recovery unit.
I grew oyster mushrooms for a season in a small tent in my living room, made a heat recovery unit out of old pc water cooling bits, namely a 120 mm radiator in the intake from outside, and a 3X120mm rad in the exhaust with a plenum, had a delta of ~2-5 degree f from exhaust temp vs intake, even on the coldest night of that year with an outside air temp of 17f, pumping 50cfm all night long, using old recycled antifreeze.
I’ve never measured the exhaust temp. But I’m assuming it is the temp of what the kiln is at that particular time. I do not introduce outside air into the kiln. Just circulate the air that is in the kiln. Running it the way I do works great. The exhaust fan pulls the moisture out perfectly. And the flow rate I have on the heater is pretty impressive to where I get as much heat transfer as possible. I will be making small upgrades down the road to maximize efficiency.
I c, so more so cooking it out (and finishing off with the dehumidifier for your kiln dried), vs blowing conditioned fresh air through it to dry.
Of course I'm now wondering witch would be more efficient overall, but its your project, and I can only try to be helpful, whether I actually am or not.
Well ether way, I'll have to lurk around to see when/how you upgrade/improve its efficiency.
@TheLoiteringKid yeah pretty much a hot dry oven with air movement. Bake the moisture out. Works like a charm.
Hey, Great video, just wondering how the heater works, like how does it bring up the temp more than the pex pipes, 👍👍 from Ireland
The heater pumps roughly 180 degree air into the kiln non stop where the pex I wasn’t getting enough heat transfer at all. If doing a lumber kiln that would work great. Where with the heater I can get temp up way faster and more consistent.
Ok thanks, does the heater heat the water to a higher temp from the pex pipes,
@damiendownes5146 when I had just the pex in the kiln and not venting I could barley get it over a hundred and that was with the dehu running. If you tried to vent with just the pex it would be as cold as it is outside the kiln. The heater will get the kiln pretty much as hot as the water source can provide depending on if your venting or not and on insulated the kiln is.
@@Treestofirewood Thanks for explaining this, what do you call these heaters, must try sourcing one,
@damiendownes5146 hydronic heater. 200,000 btu.
This makes my pork but cooking seem like lightning
Good stuff.. you had me at 40% more...
Haha yep always great when you find a way to make a little bit more money.
a 40' OTR reefer tractor trailers are better and more of them than the reefer shipping containers. plus they have walking floors for loading/unloading and its portable.
Yeah I would agree but at the time I couldn’t find one and I didn’t want a 40ft. Maybe down the road I will do a 40 if I find I need one.
@@Treestofirewood even look for a wreck or HVAC broken one from the junkyards or COPART or IAA salvage auctions.
@pnuttheclownh2254 yeah that’s a good call
There is a place near me that kiln dries lumber and they use a sawdust boiler
Yeah that makes sense for a lumber facility as they have an abundant of saw dust. Perfect for them.
Do you run your kiln 24 hours a day
Yes when I’m drying loads of firewood.
Where did you get the temp monitor system?
Elitech is the brand. There stuff is really good.
Sweet, also how did you fasten the wood strips to the wall of the container?
@ryangoff8853 metal screws
That's a nice setup. Check out Canadian Woodworks on UA-cam. He has a couple of kilns heated by an outdoor boiler. I just rewatched his video, Build a Conventional Heat To Vent Lumber Kiln Heated With a Outdoor Wood Boiler.
Also, check out Outdoors With the Morgans new video today. One of his viewers suggested a better way to cut IBC totes so you can dump them into your trailer more easily.
Is there kiln heated with direct vent from boiler or hydronic? And honestly when I dump my totes with my tractor it actually works really well for my set up. I’ve dumped over 300 totes and have had no issues and it is fairly quick. A rotator would be nice but I’m not spending that kind of money just to dump totes when the way I do it works just fine. That investment wouldn’t make sense. When I will take that money and buy another piece of equipment or leave it in the bank. Haha either way always looking at new ways to improve the process.
@@Treestofirewood their kilns are hydronic - they have radiators.
I think you're misunderstanding what I was saying about the IBC totes. His new video is saying there is a way that he doesn't need a rotator. He just cuts the totes differently. Watch his new video starting at 6:30 and watch up until 7:30. It's just a different way to cut the totes so all the wood comes right out and you don't have to bounce them up and down. I'm going to be cutting mine like that from now on too.
@James....... ok I’ll check it out
@@Treestofirewood I think it'll be worth your time. It's so simple kind of makes me feel dumb for not thinking of it myself. One of the commenters suggested it to him.
New rotating forks $8100
Check out saltwater farms sawmill. He uses a wood boiler kiln...
Correction: Firewater farms..
I will have to check him out.
Nice job putting that all together plus it works as you want it. Maybe later on look into nuclear powered to solve some of the issues. Just kidding on the plutonium.
Haha. That’s funny. You never know what I may come up with.
