Much more heat is lost along exterior walls & windows, so the hotter source water should be run there 1st. (I think?)[/QUOTE]

This is important in poorly insulated houses, with old leaky windows. It is not necessary with modern well insulated low leakage houses with modern windows. My own house has all the hot air vents toward the middle of the house without any noticeable cold areas, even at -20 deg F outside. But the house was tested at 0.85 ACH50, and the heat loss estimated at 13,000 BTUH at -20 deg F.

I want gold pipe. No corrosion, excellent heat transfer.
