    Maybe the boiler forum would be a better place to ask.

    If you installed a bladder tank, if the supply water was lost, and you had a checkvalve on the inlet, you'd still have whatever was stored in there with street pressure. Course, without a pump, it would slowly decrease pressure as you used it. Most of them aren't SS, though.

    Nor do they need to be since the water doesn't touch the steel but rather is contained by the bladder.

    A composite retention tank would not rust and would retain the full capacity of water since there is no air in them.

    On municipal water with constant pressure they should last your lifetime.

    Incorrect. The AIR is contained in the bladder and the water pressure compresses it. The tank is partially full of water when the bladder is pressurized and FULL of water when the bladder pressure drops to zero. However, we still do NOT know what he wants the tank for, because it will NOT raise the water temperature no matter what it is made of.

    Every metal tank with replaceable bladder that I've seen, the bladder went in at the opposite end of where the air valve was and the bladder connected to the water supply, not to the air valve. The air is trapped between the bladder and the metal inside of the tank. That also explains why, when the bladder ruptures, you get rusty water since the water does not normally touch the metal.

    I do know however, that the WellMate composite tank with bladder works the way you describe but then it is composite so no rust issues.

    Here is a cut away view:
