[Strawbale] PEX, Concrete Slab, Fear of Death (by contractor)

Michael,

If you can afford one, another useful item would be a heat extraction drain
such as a GFX. These recycle about 65% of the heat from hot water flowing
down your shower drain, reducing the added hot water necessary on the input
side of the shower. This can be helpful if your hot water source is limited
as well as to reduce energy use if you are using gas or electricity for the
purpose.

If you do this, naturally, you will have far less heat for "cooling off" in
other locales--but then again it works all year long and not simply during
cold weather.

By the way, could you kindly stop adding people's names to the subject line
of posts?
