Picture is worth a thousand words.. I was going out to take a pic of my tanks. Two SX110VsHere is the amtrol calculator http://www.amtrol.com/support/extrol_com_sizing.html
Volume is volume. I have two 500s vertical. Now.. as my contractor friend says.. You never really KNOW overkill. You ALWAYS find out underkill.Thanks guys!
JP; The two exp. tanks... because you have two 500 gal. stacked?
In my case it will be one 1000 gallon tank
Is there a reason that I couldn't use an sx160v? It has a 46 gallon acceptance and 86 gallon max volume.
I don't think it needs to be. Leave the expansion tank valve closed.I think with a non-diaphram tank you need to have it above the storage. You want to put compressed air in it, so drilla 1/2" hole and put a tire valve stem in it, or rig up some fittings so you can put air in through an opening above the water line.

Gentlemen;
I understand that a rule of thumb for an expansion tank is 10% of the volume.
I was wondering what some of you are using for expansion tanks. Bladder type? Make and model?
I don't think it needs to be. Leave the expansion tank valve closed.
Fill your system,
Charge the non bladder tank to 12 psi,
Open the expansion valve, and the air pressure will keep water out until you heat the water.
Of course you'll need a sight gauge and a inlet for the water on the bottom of the tank.
Lol, sounds so easy maybe I should look for a couple of old water heaters to use for expansion!
