    CAN I PUT IN 2 units on one loop?
    Seems to me the second unit would exact more heat out of the discharge of the 1st unit so two units should give me 7.4 efficiently !
    Anyone ever do this?

    It is always about your EWT and LWT. On a closed loop it could be done for a fair amount of time, but when you exert a 4 ton load on a loop that was designed for 2 tons, failure is eminent at some point. I have done what you are saying with an open loop, but never a closed loop.

    You would be using twice the power so no increase in efficiency

    Fifty heat pumps, 1 loop (building loop) is not uncommon. But not in the configuration you are proposing.

    Two heat pumps on a single loop should be piped like the drawing...
