Jtepn87. If you are planning to go with an OWB anyway, why not get it, throw a filter in line with it and if it fails and isn't fixable well oh well! I know a lot of people on here wouldn't touch that thing with a ten foot pole but its FREE! Its not going to hurt anything if you put a filter on the system. It could last you a year or 10 years. Who knows. I'd run it!

It's probably going to need new pumps, fans, thermostat, etc; and I'm not sure what would be able to transfer to another owb if this one should fail.

You might be surprised about the fan and aquastat not needing to be replaced. Pump you may or not need one that is a different size for your application. What I was actually referring to though was all of the other items such as concrete pad, in ground piping and heat exchangers in the house. All of that adds up fast!

Yes they do. I have been researching for quite a while and I have most everything picked out. The only that would change is if I find a local dealer, the. I might buy some off them as a good faith gesture
Good chance that we will be picking this thing up Sunday. Now I just have to find a shelter to store it in until I can start tinkering with it.

If you need a new aquastat I would go with a Ranco aquastat. A lot of people upgrade to them and you could easily move it over to a new unit if you bought one.

This one currently has a 2gal expansion tank plumbed to it. I'll have to take pics when I get the chance. It's 20+ years old and the belly of it is almost on the ground below it. Were Aqua-Therms made with stainless back then? This thing has a ton of rust on the outside, and in the firebox. I do like the plate right below the flu to keep heat from just running out. I also like the tubes in the firebox that appear to distribute air evenly for a complete burn. It's just the amount of rust that scares me.
do yourself a favor before anything once you pick it up.. plug the outlets  up and fill it up with water..See if there is any leaks etc..

Supposedly it has a water/antifreeze mix in it; but yeah. My plan was top it off and make a small fire in it then, just to see. If it holds, then I will begin the process of working on the electrical side of it, then the plumbing.

Before you fire that thing up, make sure you replace the pressure relief valve in it with a new one and get it pressure tested, especially if it has been sitting that long. Saw the results of one go off like a bomb one time. Was insulated and placed in a little out building. Built too much pressure for some reason and blew straight back out through the back wall and took out an 8 inch poplar tree. Insulation, building and metal laying all over the place. Fortunately happened when family was not home. Would not want to see anyone get hurt.

Do you think a foot valve would work? I know that they are for back flow prevention but I would think that pressure would open it up before reaching dangerous levels.

Also, would I be better served turning this into a non pressurized system given the age? I know that's what the relief valves are for, but I'm just wondering.

I believe you should operate it as intended. I don't think it would work well if it was designed as a pressurized unit and you used it as a non pressurized. I may be wrong through.

That is the plan for now, but with the age of the metal, I didn't know if I would be better served by it not being pressurized.

I know she looks pretty rough but Its probably fine. It looks like it has been sitting in doors and has been drained of water. Can't wait to hear about it running.
