[Strawbale] PEX tubing in floors

[Shody Ryon]

Hi Rene,
I am interested in very high efficiency heating and
cooling. Perhaps, all things considered ($), a heat
pump is the best choice. That seems to be the consesus
so far, for a retro fit of a 3 story strucure. I am
going to dig out the basment and replace the
foundation, so I want to make sure I am not missing an
oppertunity to install something under the basement
floor that would make the heat pump more efficient, or
obsolete.
Is there an informative book about high mass thermal
store and/or heat pumps and radiant floor heating? I
have "solar water heating". I am interested on how
things work, and how to make things as simple as
possible in their daily operation and maintenance, but
the theory that makes them work could be anything,
even very complex or not.
Perhaps I have been give all the info I need by the
list? such as "get an energy audit". Having made it
though the winter with minimal insulation and minimal
heating in comfort, I think I only need a minimal
system, so I am looking for super efficient low cost
systems. Is there anyone who has tested a heat sink
for cooling water and stored that cold water for
cooling? If so, wouldn't that system require a
fraction of the energy of a traditional heat pump? If
not, is it because it is totally impractical (such as
not working during a full moon)? 
Cheers,
Shody
