Ok, So some of you have seen my thread on stacking my 1000 gal propane tanks. So now I am working on getting all my system components together to start the install. That has lead me to expansion tanks. My system design calls for 2 Amtrol SX-160V's 86 gal volume 46 gal acceptance. So Correct me if I am wrong but the amount of usable water volume in these tanks is 46 gal? the other 40 gal is for the air bladder? SO the best price I have found on those tanks is just shy of $500 each :O ! So I am looking for options, I have seen Goosegunners thread on his Lp tank for expansion and this looks like a good option, is there any concerns with not having a bladder to separate the air from the water? If so could I charge with nitrogen or some other inert gas (if it is oxygen infiltration we are worried about?). goose, how is your setup working out? any problems or things you would have done different?
Has anyone else done a Lp tank or other tank (other than a purchased expansion tank) for there system? What about just a non bladder well tank? Or what is the difference between the well tanks (with bladder) and the tanks for heat systems?
