Plumbing / manifold setup

« on: December 27, 2012, 07:08:50 PM »

Have a few questions. Right now i have hooked up my plate exchanger for dhw then it goes through the house heat exchanger then returns to furnace. I want to hook up another heat ex in the basement. should i make up a manifold setup??? Or just hook it in the loop?? also if i make manifolds should the dhw ex be hooked in with the manifold or have the water go threw the ex first then the manifold.

thanks guys

Well, I finished it up awhile ago an man am I pleased. Added almost 200 gallon to the water capacity.
Installed 100ft of thermopex, an added a 2nd forced air blower on top the fire. Didn't mess with the chimney. New insulation an siding. Also put in a plate exchanger for dhw instead of coil in furnace. An wow what a differance! Also been burning straight coal. Will try an get pics.

Thanks for the reply. I already added to the water jacket, and the blower above the fire. Working on the glue pipe now. Will get pictures. The only reason I'm adding to the water capacity is it seemed like the blower ran all the time. Once it got the water up to temp it wouldn't stay hot for long an the blower would be back on. My dad has the same furnace, just older model. His holds way more water than mine an he has no trouble an heats way more than I do.

Home Made / mahoning project

« on: June 03, 2012, 11:26:41 PM »

Just took my mahoning 300 offline an doing some major changes. I wasn't very happy with its performance last year. It burned a lot of fuel, an I had a hard time keeping it going. Many times I'd come home an the fire would be out. so I'm adding a foot to the water jacket for more capacity. My questions are I've been searching around at other furnaces an like the idea of the
p@m with the multi pass heatexchanger for the flu gasses. Would adding a exchanger like that increase the efficancy?? Also any benefit to adding a 2nd blower forcing air on top the fire also??

I also installed 100' of thermopex. I think I was loosing quit a bit of heat threw my old lines. Always melted the snow.

Will post life of progress.

General Outdoor Furnace Discussion / Re: water storage

« on: January 27, 2012, 05:33:48 PM »

Is 275 gallon tank big enough, or should I find a bigger one? The main reason I'm doing this is to heat my inground pool. It's 25,000 gallons or more. I tried heating it last year an it really worked the furnace hard, hoping this would help??   My plan is to put the tank in my basement, have my pump at the furnace pump the water threw my heat exchanger for my house heat an dump into the tank, then return to furnace.  My mahoning has heating coils in the back of it for dhw, an one for the pool. I'm gonna mount them in the storage tank then.
Hope it works.

General Outdoor Furnace Discussion / water storage

« on: January 27, 2012, 04:35:54 PM »

I have a 275 gallon tank, would it be worth adding it for storage? This would double my water capacity. Also I have a taco 0011 pump, would this pump be enough to pump into the tank an back to furnace?? Or would I need to add another pump on the return side? The furnace is about 70ft from the house an its a mahoning owb.
