[GBlist] Solar Hot Water Heating - Slab on Grade vs superinsulation

["Richard McCabe" <rmccabe@alumni.princeton.edu>]

PS with a well insulated house, good windows, hrv, etc you shouldnt need
much of a heating system or any heating system at all see
http://www.cepheus.de/eng/
and some examples from Austria http://www.energieinstitut.at/cepheus.html
then click on "Zu den österreichischen CEPHEUS-Projekten... "

Superinsulate, and you don't need PAHS or active solar.  Small south facing
windows are enough.  Especially if you use insulated blinds at night.  The
people and appliances are just about enough to heat a superinsulated house,
depending on the climate.  Build in as much thermal mass as is reasonable to
dampen temp swings, (like thick plaster walls). And there are no moving
parts!
