Hello All!
Previously I was asking about the size vs. efficiency of storage types (pressurized vs. non) and got some really good information. It didnt really point me in any particular direction, but it turns out that my storage choice was made for me.
As part of my day job work, I get to check out various commercial construction sites, and inspect progress on things. One of these happened to be a project where large cast iron sectional boilers were being removed, and new condensing natural gas boilers were going in. I was shooting the breeze with the site super, and he was mentioning how he wasnt looking forward to getting a new 2500 lb boiler down a staircase into the boiler room. I joked with him that he could come and do mine if he really wanted to, but that I really needed some tanks that would fit in my basement. He pointed his thumb over to the scrap metal dumpster they had on site and said "how about those?".
Turns out they have removed three 220 gallon bare steel expansion vessels and were going to send them to the scrapper. I still need to work out how to get them from the job site to my house (which is about 2.5 hours away), but they are mine (after sufficient palm greasing)! The best part is that they are 30" diameter by 77" tall, and my free space is actually 80". So I have just enough space to insulate underneath and put a layer on top. They have a standing ring welded onto them so no cobbing needed there, and they are even ASME rated.
Awesome.
The only downside is that they are tapped on the long "side" only, not on the very top, so I wont be able to get the peak BTUs out of them. (They do have two 1/2" tapped ports on the top, Im thinking good for thermowell and air vent) Does anyone know of a curved dip tube that could be threaded into the existing port on the side that would direct/collect water from the very top/bottom of the tank? Or is the few inches difference not going to matter?
