Home Made / Re: Masonry OWB build
« on: April 14, 2013, 11:22:43 AM »
Welcome.
What size storage are you going to have? I think with that type of set up and a smallish hx you will need a large quantity of storage, maybe a 1000 gal. or more.
I think the masonry idea is a good one but my thought on it is to embed a tank above the fire box, heat that and pipe it to storage tanks.
Good luck and keep us posted.

dwneast, I think this one is at least 30 years old. It came out of a house we put a new foundation under.
It will crank that's for sure! I have it at an idle right now, it's about 45 out and 74 in (way too warm for our taste) LOL we are used to it being 67-68.
I had to replace my fan, the bearings went out in it. Luckily I have a plumber buddy who had one laying around and gave it to me.

Nice joe, I'm glad to see that I'm not the only redneck on here. 
My hot air one is a triple wall chimney, 10", 12" and 15", I insulated between the layers with vermiculite. The cold air line is only wrapped with one layer of reflectex.
Here's a couple of the new location.

I haven't tied it into the existing ductwork yet. I had a spare door way so I took the door off and put in a piece of plywood. It is right beside the furnace in the cellar though so it will be easy to tie it in.
We were away for about 5.5-6 hrs this afternoon, came home to 73 in the dining room.
This furnace doesn't really use all that much wood and it's pretty easy to use. I put three chunks in at 11:30 and still had one stick and nice coals at 6:00. Of course it's not that cold out, around freezing.
Do you have a write up of your build?
thanks,
dave

I got sick of paying over 4 bucks a gallon on fuel oil.
I have been testing the unit at the garage for almost 3 seasons and it works great.
More info on it here http://www.arboristsite.com/firewood-heating-wood-burning-equipment/154832.htm
I'll try to get a couple pics up later. It was dark by the time I got everything done including filling the dump trailer with splits and parking it beside the stove.

« on: February 14, 2013, 08:23:56 PM »
Sounds good except you insulated pipe. The $11/foot will seem like a bargain when you have to spend all of your time loading wood in it. Don't get me wrong, I'm all for DIY projects but everyone will tell you the pipe is important.
Is the pvc large enough to slide the pre-made foam'd pex into later?

I'm kind of surprised no one told him to check his temps on the lines at the boiler and in the house. That would be a sure sign if you are losing a lot of heat in the pipe. If the run is only 15' I wouldn't think there would be much loss unless they are going through some water in the big pipe.
Also if only a 15' run I would go to my nearest Lowes or HD and buy me some 1" pipe and start there.

Two feet is a long way for a smoke pipe through water! Maybe you could make the fire box closer to the water jacket with less water in the rear so you would only have about 6-8" of smoke pipe in the water?
I think spiral fins on the outside of firebox would help heat transfer more than anything and give your water a path so to speak.

Good start! I can't answer most of your questions. What I know, I would run one pipe in 4-5' , I wouldn't tap for anything, weld in bungs IMHO, are you going to have a smoke shelf or baffle plate for the stack? I would weld in a plate across the top of firebox almost to the front so the smoke would go to the back, up then to the front and out. with a secondary air intake. (just one of my ideas).
Can you add some sort of baffles to the outside of the firebox so the water has to circulate in a certain way? Kind of like a screw. That and they would act as heat sinks.
Anything will heat water, heating it efficiently is the trick. Why burn 20 cords when 10 will do?
I wouldn't use galvanized but make sure you use water treatment.

I don't quite understand, was the firebox full of ash or coals? Is that the reason you could only get one 3 inch round in?
If the firebox was full of hot red coals I would say your draft never shut down.
I have a question for you, why in the world would you want your house at 75?
If my house was that warm I would never get anything done, I would be like a zombie.

Interesting concept, dry your clothes and get heat from the same machine. It would work quite handily in my house as the dryer is in the basement.
