Getting close

Looks good! When you are piping it all up, make sure you have a provision to purge the air out of it.

nice copper work!
how will you be managing injecting and pulling the hot water from storage tanks and stratification? will you have ports in the top of each tank? if left as is (and you may just be doing this for setup now) wont they thermosiphon the hottest water to the top tank? yet you will be feeding/returning from both? correct me if my thoughts are not in line...

Didn't pick that up first time I looked (the pipes) - looks like these are being run parallel & not series? Usually the bottom of the top tank would get plumbed directly to the top of the bottom tank to make it kinda all one tank (in series), then boiler in/load out at top of top, and out to boiler/back from load at bottom of bottom.

Some do return high temp emmitter return to the middle of storage also though.

But pictures can be deceiving...

unless i am missing something, what you are describing works great for tanks side-by-side (as i did). stacked, not so much. as maple said, ussually when they are stacked one tank feeds into the other with supply/load at top of upper tanks and return at bottom of lower tank.

nwomatt, That will work fine. That is how I have mine.

Can you explain how this works? Or put up a diagram with all the plumbing?

This is how i have mine plumbed.

Thats what i thought i was thinking. Pros and cons of this setup vs what i previosly described?

It works great for me. They raise in temp. evenly and draw done the evenly.

looks very nice but im sorry i still dont understand plumbing storage in that manner.
henfruit, i see the valve to your top tank is half closed. did you have to play with this much to get it right?

Looked funny to me at first, but if you draw it out and work it through I think it may be as good or better even than top, bottom-to-top, bottom. Only one tank fills or draws at a time and the water doesn't have to flow from one tank to the other.

The ball valves will balance the two tanks so that my temps are even.AS I type this my tanks are within 1 degree of each other.

how does only one tank fill or draw at a time? why is it a disadvantage to flow one tank into another? yeah it works. flowing any volume of water to/from your storage "battery" in any manner will "work". i am asking why this might be better? it just seems like more plumbing to me and doesnt allow stratification to be used optimally. only trying to figure out what i missing to fully understand this setup.

nwomatt, can you please say a little more how you moved the tanks into position and stacked? These are 500's?

Thanks

I have an I beam in my basement. I wonder if that would support an empty 500 gal. tank?
I'll start another thread. Sorry for the diversion.
