1) you are correct, LMTD was for rads
2) yes, to make sense the LMTD should be applied to both sides which is why I agreed with you
re system modeling, it is difficult for me as I think in terms of system testing
what Stew seems to be suggesting is component testing done differently for the use in system modeling, your "Outlet + 2/3 metre of tubing" seems similar in intent
so are you guys proposing rad testing using the outlet temp as the set point ?
the equip does not care, but I am mystified
I'll go get a drink, then start on "U"
