The person who'll be helping me with the install, and has installed these
systems before says that the aluminum heat diffusers you can apply along
with the tubing are useless, especially if you're using water heated to
about 100F.
Does anyone have any comments?

Heating engineers spent a lot of money on R & D to come up with the ideal
method of heating the floors. What has your friend done for testing? Use
the diffusers.
