    Can any reasonable installer follow?

    The 4' at each end of the floor trusses is open with solid web connecting.

    give me more head, delta-t and flow

    typical winter flow


    9,000 btu emitter output

    8°F delta-t ----- [ increasing with supply temp above 130°F ]

    2¼ gpm emitter flow + 1¾ gpm bypass flow @ 6½' (2.25 psi) --- [ emitter flow decreasing with increasing delta-t and increasing supply temp ]

  • Am I missing something Mike?

    is this some sort of test? Given the impeccable knowledge you`ve shown in the past here, can`t you do the math?
