Plumbing / Re: pump size

« on: December 04, 2014, 06:47:31 PM »

The exchanger for the house is 12x15 (4 core) and I used 1" pex line with 90s at the owb and only 1 - 90 at the top of the exchanger in the garage. I ran the return from my primary exchanger to the top of the garage exchanger, don't think it would be vapor locked.Figured it would be easier for the pump to dump in the top than push from the bottom (right or not)?

Plumbing / pump size

« on: December 03, 2014, 03:17:08 PM »

I got my homemade owb on line the first of November. It is 100' from the owb to the heat exchanger that sits about 4' lower than the owb. I installed a taco 007 which seemed to work fine till I later put a heat exchanger in my garage. It is  9' to the top of it. The 007 will not pump to the top of it. Right now I have the heat exchanger in the garage bypassed. What size pump do I need, and do I need a 3 speed? THANKS for any help.

Home Made / paint on water side of fire box

« on: February 01, 2014, 04:41:43 PM »

  I read in a post that the water side of the water jacket should not be painted . Figure this goes for fire box too . my firebox is a 120 gal propane tank with some nice thick paint . I started removing some but after 1/2 hr  I had only cleaned up about half of the end. Does this really have to come off . I know the treatment needs to make contact with bare metal to work properly . I guess what I am really wanting to know is what kind of problems would develop from leaving the paint on ?

General Outdoor Furnace Discussion / draft size

« on: January 26, 2014, 08:25:42 AM »

I am working on build, and am at the point of installing the forced air draft pipe under the grate . My question is, what size pipe should I use 3" or 4". What cfm blower- and does it have to be multi speed? Get this done and I will be back to pick your brain some more. Thanks for all the help everyone has given so far.

Home Made / Insulated fire door???

« on: January 13, 2014, 06:09:54 AM »

 Ready to build the door for my outdoor wood and coal  boiler. It will be 22x22 1/4" plate 4" thick. What is  the best way to insulate it? If I use ceramic , do I use a couple layers of 2" ceramic blanket or some other type?
       Not familiar with using refractory-If this is the way to go lead me thru the process (how to mix and apply.)
                    Thanks for the help fellers. By the way I have water here in Southern West Virginia!!
