General Outdoor Furnace Discussion / Underground lineset dealer on eBay
« on: April 11, 2013, 05:22:47 AM »
Has anyone dealt with this eBay seller?
http://www.ebay.com/itm/300509247370?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
They have a lot of info on their underground line products on each auction page, and if true, it sounds good to me.
Any thoughts?
I only need about 50' for my install, and I am planning on running them inside of a 6" or 8" SDR PVC conduit.

Plumbing / External Boiler Piping and Bung Location/Size
« on: April 02, 2013, 08:43:47 PM »
Still trying to determine where to place the bungs in the water jacket of my homemade furnace and was wondering...
If I was to extend metal piping from a bung location (on the side of the water jacket barrel) to the back of the stove, is black or galvanized pipe preferable, or does it matter?
When I got to the back of the stove I was going to turn the metal pipe down with 90s, then transition to the pex a foot or so above ground. All metal pipe and pex to be 1".
And what size bung is recommended for an aquastat drywell, and a bung to put a thermometer in?

Home Made / Homemade "Tank-in-Tank" OWB-Ozarks Hillbilly Edition
« on: March 24, 2013, 01:10:47 PM »
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!

Plumbing / Pump Location?
« on: March 24, 2013, 08:23:35 AM »
What are the pros/cons of locating the pump at the OWB vs. inside the house?
My system will be OWB to DWH hx to hx coil in plenum of an upflow propane furnace in the basement. Total difference in elevation of the system from one end to the other will be 3-4 feet, and a total run distance of about 60', one way.
I have read here on the forum that it is desirable to have the pump on the supply side of the system.
Unless there is a good reason not to, I think I want to put my pump somewhere in the basement, and inline before it gets to the hot water heater.
The only downside I can think of of that arrangement is pump noise, and unless these pumps are VERY noisy that won't be an issue for me.

Natures Comfort / NCB-80?
« on: February 12, 2013, 09:27:55 AM »
Hello all,
Longtime lurker, looking for info about the NCB-80, and Natures Comfort in general.
Not having any luck finding much on the NC website, looks like it is a new model so maybe they haven't had a chance to update their site.
Thanks!
Joe
