Home Made / Re: Homemade "Tank-in-Tank" OWB-Ozarks Hillbilly Edition
« on: April 02, 2013, 05:16:52 PM »
Here are some pics of the propane tanks we cut the water jacket and firebox out of. We ran car exhaust through the tanks for about 30 minutes before cutting, have done many using that method, and still alive to tell about it. 
You are on your own if you try it though...

Home Made / Re: A few questions and my build
« on: April 01, 2013, 06:33:11 AM »I love the horizontal pipe through the water, I will be changing my door. I did make an insert that goes in my horizontal pipe to help limit the flow of heat out of the stack.
Could you take a pic, or describe your horizontal pipe insert?
I am going to buy a pre-manufactured door/frame/fan assembly for mine, considering the cost and time involved to make my own I think this will be a better deal for me.

Yes I did figure it out, and thanks for the pic. I posted a sketch earlier in this thread of what I came up with, my buddy made a nice ACAD drawing of my sketch and converted it to .pdf, but I haven't been able to attach it to this site yet.

By the way, I did look at the Central Boiler site and they did have a lot of drawings but the only water heater setups I found looked they were for sidearms.
Couldn't find a diagram for a plate-type exchanger. Maybe I missed it?

« on: March 26, 2013, 06:58:28 PM »Thanks Scott, great info. WoodMoJoes diagram almost seemed too easy. I had been given a quote for OWF with sidearm and mixing valve but I think I like this setup better.
Yep it's really that easy!
If it wasn't that easy...I wouldn't have figured it out!

Here is my design sketch of a proposed plumbing schematic. The color of a couple of the lines may be a little misleading, but I think I have the flow directions and connections correct.
Please give it a look and let me know what you think, thank you.

« on: March 26, 2013, 10:18:31 AM »...Be sure and have the water flow correct when you hook up the heat exchange. The domestic water and the furnace water need to flow in opposite directions and the hottest water needs to go in the top of the coil if you put it above the furnace.
I am pretty sure I understand what you are telling me here but would you mind explaining why you do it this way?
That is, why does the domestic and furnace water need to flow in opposite directions, and why does the hottest water need to go in the top of the coil?
I'm guessing the answer is that those arrangements are just basic, simple laws of thermodynamics but am really interested in knowing the "why".
Thanks!
Also, I have sketched out how I think this system will plumb, I will post it in this thread shortly.

Was planning on using a 20 plate flat.
Here is a couple of pics that shows my layout.
The underground will come in through the basement wall about 8' to the left of the water heater, fairly close to where you can see my existing 1" PVC line coming in from the well. Then I was thinking I would extend a board down from a floor joist to mount the pump on maybe? And from there...
Also thinking I can get a 19x20 hx in the very top of my plenum (just below the floor joists) above my AC linesets, without having to unhook them. My vertical plenum dimension is 20x20.
Appreciate the help!

Here is a revised drawing, firebox is now fully round. Will post some pics of the tanks next chance I get.

Thanks XJCraver, those all sound like great benefits of putting it in the basement, I was sure hoping it was acceptable to go that way. My office/mancave is right over where the pump will be, I kinda hope I will be able to hear a hum from the pump, just so I can keep tabs on it. Ah, the sweet sound of $avings.
Yoder, is there any place on the this forum, or on the web, that I might find some schematics for "typical" plumbing layouts for DWH and HX hookups. My setup will be OWB to house, then hit the pump, then the DWH, HX coil in plenum, then back to OWB. I have found some pics here on the forum but having trouble telling what is actually going on most of the time.
I built (and plumbed) my house...but am not a "plumber", so whenever I encounter a new concept it takes me a while to get my head around it.

Thanks skorpyd. I studied your thread and got a lot of ideas for my build.
I also am considering going with a 90 turndown on the horizontal tube in the firebox, but wondering about creosote buildup at that point. I guess, worst case, most of it could be cleared from the opening at the outside end of the tube, and the downward facing section could be accessed from the firebox.
Also planning on copying you on getting the outer structure framed and firing it up without putting the insulation/skin on, to check out operation before it's all sealed in.
How did you get your tanks safe to cut into (explosion hazard)?

After consultation with my financial advisor (aka wife), a neighbor (master welder and fabricator) and many hours of studying the forums here, I have decided to attempt an OWB build.
It's great to be able to see the great work that so many of you have done here, get ideas, and maybe avoid some pitfalls along the way.
I have attached a preliminary drawing .pdf to this post, please check it out. I'm sure a lot of the dimensions will change somewhat, but it will give you a pretty good idea of where I am headed.
Outer water jacket tank is a propane tank, 41" O.D. x 79" long, 360 gallon capacity. One of the half-sphere ends will be cut off, flat plate will be welded to that end to accomodate the 20x20 door opening.
The firebox will be 30" round piece of propane tank (with a section cut out full length on the bottom and flat plate welded in) x approximately 48" deep.
Water capacity should be somewhere around 160 gallons when completed.
Flue will be 6" Sch40 steel pipe, it will extend about 12" into the firebox and exit horizontally into the water jacket, then I will go vertically with more 6" after it exits the water jacket. The horizontal piece will extend outside beyond the flue and have a cap, to access the horizontal tube for cleaning.
Door will be a pre-manufactured 20" x 20" unit with draft induction fan built in.
No ash pan, no grate.
1" bungs will be provided on the back end of water jacket, from top to bottom: 2 for return, 2 for drywell (aquastat) or thermometer, 2 for supply. Returns will be extended up high to be near the front of the tank, supply will be drawn from down low and near the back of the tank. A 1 1/2" or 2" outlet will be provided on the bottom for tank drainage.
A 2" threaded bung already exists in the middle of the top of the water jacket, for fill point, venting, water level float....?
This whole assembly will set up off the slab on a metal framework, and eventually all will be enclosed/insulated in a metal framed and sheathed structure.
All comments/thoughts/suggestions are welcomed!

Thanks Scott. I definitely want to put enough ball valves/isolator flanges, etc. on the plumbing system to allow ease of service and maintenance/parts replacement.
Sounds like the arrangement you are talking about would also give me a point to attach a garden hose and run it out my garage door to drain my underground lines if I were to need to, I like that.
Glad to hear those pumps aren't too noisy, I'm still leaning on putting it in the basement from what you guys have told me so far.

Thanks for that Yoder, good info there.
I didn't mention in my original post, but the OWB will be the highest point in my system...sounds like I should go in the basement then?
The OWB will be a tank-in-tank homemade, I will be posting a thread on it in the Homemade section soon.
Is there a way to insert .pdf files into a post on this forum?
