what I've heard from the Bau-Biologie people is that in-slab heating (and
associated movement of water) leads to chronic foot and leg problems....they
now recommend heating lines in the lower portions of walls (near the ground
so heat still rises) instead. Supposed to alleviate the problem while still
using water heat from low in the house...
