General Outdoor Furnace Discussion / I Did something Stupid
« on: January 19, 2014, 05:48:37 PM »
I wish more people would write in sometimes and let others know of their blunders so others can laugh and/or learn from others mistakes.

This is my first year with my OWB and I'm learning. I am running two loops, one to the house and one to my wife's sewing shop. When she's not sewing much, I kill the pump to that loop.

It got down to single digits here a couple weeks ago and my wife did not get out to the shop any. Yesterday she goes to the shop and water goes everywhere. Froze and broke heat exchanger.

I haven't replaced it yet, it's leaking in about 20 different places. This was my $200 mistake. I was a tightwad and will be wiring the pump to run all the time. it never even dawned on me that the thing would freeze; my head was just not in it.

There you have it, run your pumps all the time in the winter.


General Outdoor Furnace Discussion / First Fire Ever In My OWB
« on: October 28, 2013, 07:49:23 AM »
I finally got my Earth Wood furnace hooked up, one zone anyway. I will be heating my house off one loop and the shop off another.
I wanted to share a few things that I learned here and thank everyone for there shared knowledge:
  1- take the extra time to do the stove pipe the right way. I was going to run mine out the side wall. I boxed the roof beam to make way for a roof penetration and then took it out the corrugated roof. This is the way to do it!
  2- Do what you can to reduce 90's and other restrictions. I have not hooked up my fixed plate yet as I had to prove that the thing would work to my wife first. She doubted that there would be any real heat and wouldn't let me spend any more money until there was evidence. I have a total of 4 90's in the whole system.
  3- While your there, put in a connection by the pump to connect city water. I was able to shut off the top valve (pump supply) and push the air out with city water. Open the pump supply and prime the supply side.
 4- Bleed the air and bleed the air and bleed it again. It did take several attempts before I got most of the air out.
  5- I had a boil over- My stove did not have a damper and solenoid to block air from coming in through the blower at idle. Duct tape for now. Solenoid ordered from Grainger and pictures from members on the Shaver side for a retro fit.

My house is all electric and the heat from my heat pump in the winter is just above room temperature air. The air from this OWB is HOT air and when the blower kicks off, you can still feel a little warm air coming through the vents from convection. Wife is happy and I can spend a little more to finnish the hot water and her shop.

Why did it take 20 years to do something???

Thanks for all the great shared knowledge.

General Outdoor Furnace Discussion / OWB Stack question
« on: October 15, 2013, 06:31:35 PM »
My OWB is in my barn. The stack comes up 6ft, turns 80-85 degrees and exits the bldg with a 6ft 6" stove pipe.

Does the stack have to end in a vertical orientation or will this work?


Plumbing / Check Valve in Pump Yes or No
« on: October 04, 2013, 01:39:32 PM »
My pumps have a check valve in the inlet. Do I keep them in or pull them out?
Do these effect the flow charactoristics of the pump?


Plumbing / Pump Selection
« on: September 25, 2013, 08:26:56 PM »
Reading the previous post, I hope I got the right pump???

I have a run one way of 220' and a 30 plate heat exchanger.

What pump would you suggest?

I have a Grundos UPS15-58FC.


Plumbing / Connecting the Exchangers
« on: September 23, 2013, 07:20:58 PM »
I know that 90's really reduce the flow but how do I connect the FPHx and the Water to Air exchanger without using a few?


Plumbing / PEX Install Questions
« on: September 15, 2013, 08:00:40 PM »
I've got my Underground mostly installed but have a situation.
My house is on a crawl space and the utilities underground interfered with my pex underground. So I'm going to have to come above ground level for the last 6ft. I will build a patio over the pex so there won't be any trouble there but,,,,
Do I insulate the insulated pex?  Should I use foil board and box it? Foil board and wood inclosure?

I really could use some advice.


Plumbing / Earth Wood Help
« on: June 23, 2013, 05:42:02 PM »
I bought a previous generation Earth Wood Mountain Man 500 and have a question.

The current model shows the supply coming out toward the top rear of the unit and returning toward the bottom. My unit, the supply would actually be going across the top at the rear. Does this sound right?


Earth Outdoor Wood Furnaces / Port Question Mountain Man Series
« on: May 13, 2013, 08:51:45 PM »
On the rear of my Mountain Man I see where the domestic connects, and on the right hand side is a supply and return. Supply at the top? and on the left side I see another supply (top) but no fitting at the bottom.
Is is just plugged under the sheet metal?


I got me an Earth Wood Mountain Man furnace and have a few questions on the installation.

1: I read that the Hx in my central unit needs to be installed prior to my back-up heat strips. That will be a difficult thing in deed. Can I mount it say 12-16" beyond the strips or will the strips harm the Hx?

2: Will I have to increase the blower speed? and if so how?


Fire Wood / New Splitter Project
« on: May 10, 2013, 12:40:40 PM »
I am getting everything together to start a new splitter build. I have hydraulis pump off a John Deere 450 dozer. It was front mounted to the engine in the original setup. I know it ran the 6-way blade on the dozer, would it be appropriate to use on a splitter?
I have read through most of the posts and have learned a lot. I am going to put the wedge opposite the hitch, I never thought about all the wood piling up between the truck and the splitter.
Thanks for the great knowledge here.
