No Wood, Still Winter, Now What? Pg.-1

[Rick Stanley]

Ran out of wood yesterday.(burning oil grrr) Now I have 1875 gal of water and exposed plumbing in an unheated building in February? Yup, but I have planned for this. Now the test. It's crude, temporary and manual, at this point, but I think it's working. Will dress it up after I'm sure it works. It was 19 degrees last night. So far, so good.
So I put the Garn in a corner of an existing building. Kept the boiler and all the plumbing within an insulated enclosure.

I insulated the crap out of everything with fiberglass batts-

Hopefully the warmer temps will come soon for you.
No wood pallets in the area for free that you can burn?
Also, was the Garn un-insulated previously while burning?
At the very least you should have better heat retention when you start burning again.

Another thought: If you can run your pump several times a day even without the higher temps. in the line, it would
help not to allow the line to freeze.

When we did the trench for the insulpex and control/power wires and water line we didn't want to undermine the old 40's vintage slab, so I ended up boxing-in a section of exposed line so it could go through the wall instead of the floor. ( Chris Holley thinking ahead) I boxed it with 4 inches of blueboard, then 2x10 PT, then painted aluminum (actually a piece of aluminum gutter I had). So as far as freeze-up protection, this is the weakest point.

Pg.-4

So, the key to the whole thing is that the Garn pump can be turned on from the house so circulation can be provided as freeze protection if needed AND saving back some wood to heat the tank up. I don't know how long the tank will stay warm with no heat load on it, but I'm gonna fine out. I'll keep you posted. It's suppose to go down to zero later this week.

 

[Rick Stanley]

Nyedge- it was insulated all winter, 2 winters actually. I just wanted to show the insulation pics. No free pallets around, but when the weather clears, there are some standing dead oak out back that I can grab.

Hi rick, Nobody said being a boiler operator is easy, there is always something to do! Do yo have oil or do you have to buy, bioheat fuel value calculator says if you buy oil at $3.44/gal=$460.00/cord. The other way to look at it is if you had to pay $250.00/cord=$1.83/gal. buying more wood is cheaper even at 250 cord if you paid more than 1.83 for the oil in your tank, unless you are sitting home for most of this winter without a income and bought oil in the tank, like me.

Hi Tom, You're right on the calc. I did some math on that too. They're getting 270 for wood around here right now and oil is 3+, diesel is 3.85
I have 275 gallons of $2.79 oil bought last Fall. Plus, I'm a wood burning/cutting fool if my back holds together I can get out some standing dead oak. Really want to focus on next year and the year after while it's still good going in the woods though. Hopefully I can get a few cords ahead to sell some day. You're right. Always enough to do

 

[Hydronics]

Rick,

If you can't get dry cordwood nearby have you priced biobricks in your area?

 

[Rick Stanley]

Rick,

Hydo- I'm not familiar with biobricks. How do they compare pricewise with wood? Where do you get them?

 

[Hydronics]

Rick,

Tractor Supply here sells them for $250/ton, there is a place here that sells them for $200/ton in the summer. A ton is the equivalent of a cord but less volume, they're very dense.

Rick if that's your skidder, you are one lucky man. I'd love to have a toy like that, all my wood is on downhill slopes and with all the snow we have its darn near impossible to get any now. I'm like you out of wood pretty much hand to mouth right now, spring could come soon. My tractors drags bottom now and even with chains its tough going, actually had both tractors stuck last weekend at least not both at the same time. My wife doesn't think I need toys like a dozer or skidder, so I just use longer chains and cables. I liked the old line shaft in the rafters above your boiler,we used to live on a farm that had one of those.

Yup, it's mine. Bought it a couple years ago. Kind of an odd situation. I want it to stay cold so my skid trails will hold up (lotta soft ground) so I can crank out a couple years worth of wood in a hurry (well, fast for a broken down 52 yr old), but the colder it stays the more heating fuel I'll burn. Am hoping this is the year I'll get ahead of the wood curve. Suppose to stay cold rest of the week after this storm goes through.

 

[muleman51]

At 52 I could cut wood all day, at almost 60 2-3 hours is a great plenty. Makes me wonder how long I want to keep cutting wood. I was hoping the last boiler I bought was going to last but its about shot now unless I rebuild it and I'm not that excited about doing that. The thought of buying another one and having to feed it for another ten years or hopefully longer is getting less exciting every year.

 

[Whitepine2]

Cheer up Fred in a few hours you will be out of Feb. you will never see Feb. 20011 again ever just something to think about to cheer you up. I have been cutting myself to get enough for next year but with rain it's hard to get away from mud. Better weather this week can give it he-- maybe,good luck.

 

[EricV]

Are your lines isolated with valves? Maybe you could just drain the lines, capture the water and dump it back in when you get warmer or more wood. Maybe a small fire once in a while just to keep the boiler above freezing but you wouldn't have to worry about the lines.

I just bought 4 cord (logs) (12 face) for $400. I hope to get a few more loads like that this summer. Since I got the Geyser heat pump water heater from Tom in Maine I no longer burn in the summer so 4 cord will do me well for heat and hot water for the heating months.

 

[RowCropRenegade]

Don't feel bad Rick! You are not alone. I ran out of wood Saturday. Roughly 5.5 cords worth of ash, maple, black walnut and cherry. Hate to see it gone! Was too busy installing Garn last winter to get further ahead. Good news is that I have about 10 cords c/s/s for 2011-2012 winter.

What I've been doing is burning pallets. 15 years or more ago, Dad got paid to haul pallets from a local company and dump them in his woods. 500 bucks a load! The pile is monstrous. All oak pallets and the Garn loves them, cause they are long. Have to be careful with puffing, though. They are very dry. Double bang for the buck though. Dad paid to haul them. I feed them into Garn for btus. Win Win!

Do you worry about the paper backs on the insulation so close to the flue? I haven't seen any reason to worry about it but was wondering if you were going to use wall covering at some point?

Let me know how you get along with bio bricks if you decide to use them. Attached pic rear of my G2000.

 

[Rick Stanley]

Hi Rowcrop,

I haven't been too worried about that craft faced insulation touching the flue pipe. It's been like that since day 1. I guess it's ok. The pipe hardly gets warm to the touch. I had planned on covering that whole inside of the enclosure (I call it the control room ) with OSB. Just hadn't got to it, but when I started the Garn up last Fall, of course, I had condensation running a stream down the back of the thing so was glad I could get at the insulation to take it out so it wouldn't get wet. Now that I say that, it occurs to me that if condensation can get out through there where the fluepipe screws on, why couldn't fire come out too if there were some kind of malfunction. Maybe a question for Heaterman. I said HEATERMAN!! lol. Maybe he's listening............

Wow, good for you on the getting wood ahead for next year. That's awesome!! AND that pallet deal is great. For you and your Dad. I have, I'm guessing, 8 full cords pulled out of the woods and about half of it cut to length, non split yet. I'm just gonna keep cutting trees and draggin em out till I start getting into the mud. I'm hoping to have enough for 2 years burning and some to sell.

I spotted some more standing dead oaks today out back so I think I'll snag a few of them later this week and fire the Garn back up. So I probably won't do the bio-brick thing. I'm too cheap. I don't know for sure if they are even available locally.

Great looking install!! Is that rigid insulation??

 

[RowCropRenegade]

I know what you mean about being too cheap for bio bricks! lol, installing a Garn will put you in the poor house for a couple years haha! (Still would do it all over again)

I really like the rig you are using to gather logs with. I bet you can handle some behemoth trees with it. Dad and I went together to purchase a rig ourselves for variety of uses including firewood! Picture below.

I suppose if the caulked joints on the flue wore out or the flue became disconnected would be the only cause of concern. Highly unlikely but ya know Murphy's law.

Hope you get her back online! Winter is giving us a break here at the moment. Hit 45 degrees. 20s at nite. I'll take it!

That insulation is the "Heaterman Garn Sweater" insulation kit. I like it very much, saved a lot of hassle in the installation process.

 

[heaterman]

Last winter a guy who has the sweater on his 2000 took his family on vacation, leaving on a Thursday and coming back the week following on sunday. So figure 9 days. He asked me what to do and i told him to run it up to 190 or there abouts and shut off the sirc going to the house. The Garn sits in an insulated but unheated room and it was still around 100* when they got back. IIRC it averaged about 5,000 btu per hour heat loss.

One of my boys just ran out today and had to go buy some dead oak. Around here that is not a big deal as he got 2-1/2 face cords (22" length) for $100. Delivered. Hardly worth the time and expense of doing it yourself for that money.
His old Hardy works great but eats wood like it's going out of style so he's stashing cash for a Garn someday.

Rick:

I had the creosote running out from around the ring on the exhaust flue on my chimney as well during the first burn. I also noticed on subsequent burns that I had some "smoke" coming out from beneath the welded on ring...right against the back wall of the garn and this ring. Now, I had no silicone at all at that point. So I put on the high temp silicone, then some aluminum tape over that, and then another layer of silicone...and then more tape. I boxed around the flue giving myself about 3" of clearance...and I take a peak in there once a month or so. I haven't seen any signs whatsoever of that "blow through".

Garn told me that is what the silicone is for! LOL On the joints of the flue, and the flue to the ring collar....sure. But I didn't expect to see that from the ring to the garn back plate surface......

I bought my logging winch for the 3PT....hope to get it on this weekend...so I hope to be skidding soon myself. With smaller loads though than you can pull!

I've never had creosote or smoke from around the ring, or anywhere else. What I have is pure clear water (condensate) when first starting up the Garn from cold (less than 70 degree) water. I think it's normal dew point science crap, but it's curious how it comes out, though. Maybe as the tank heats and expands, it just seals itself.

You'll love that new winch. Probably gonna have 60+ ft of maybe 3/8" cable. I'm dragging a 3/4" cable with 7 slides through crotch deep snow,, boo hoo

So, the key to the whole thing is that the Garn pump can be turned on from the house so circulation can be provided as freeze protection if needed AND saving back some wood to heat the tank up. I don't know how long the tank will stay warm with no heat load on it, but I'm gonna fine out. I'll keep you posted. It's suppose to go down to zero later this week.

So, over five days of just sitting with no load on it, the tank temp dropped from 135-105. With predicted near zero temps last night, I built a fire.(it was +3 this morning) I was surprised to see that just ONE LOADING raised it from 105 to 140. #1- There was no load on it. #2- during normal operation I never let it get that cold. #3- When starting the Garn for the season, I never noted the rate of increase through that range. I just kept throwing wood in until it hit 190 or so. BUT, I'm willing to bet money that one load of wood won't raise the temp as much, starting from 140. We'll see tomorrow, I'll build another fire tonight. Stay tuned...........

ps- didn't Jim's report note poorer heat exchange above 140?

 

[Jim K in PA]

Rick - I regularly get a 35-40 degree rise on a single load of wood in my 2000 with no heat load. This AM I went from 168-192 on a single load of wood with the morning house load on it - in ~90 minutes.

You are correct that as the water temp rises, delta T is decreasing and efficiency starts to go down. Not a lot, but some. 140-180 will take a bit more input than 105-140.

Jim, actually I was referring to the other Jim's comparing of garn and wg....

Anyway, what kind of wood are you getting that much rise with? Last nights load was, now that I think of it, was almost all very nice red oak. But during most of these past 3 months, I've burned some pretty crappy stuff. Lot of pitch pine and some red maple dead falls, some kinda punky with good red maple and nice red or white oak mixed in.
But, better days are coming. Made 3 trips with the old skid-dog yesterday. 12 trees mostly oak. Restin today. Snow is deeeep!!
Anyway, whadiyaburnin?
