    The terms you're using aren't industry terms. Need more information or pictures of what your looking at/talking about.

    The only difference between the two is that one of them can be used with non oxygen barrier tubing, and the other can't. Their potable water expansion tank is the same as the radiant exp. tank, but will need the diaphragm pressure lowered to the same operating pressure as the appliance it is serving. I believe it comes precharged at 40 PSI, versus a heating tank precharged at around 12 PSI.

    And the connection size on DHW tanks is 3/4
