Bill Dunster of BedZed fame has designed another type of house, RuralZed:
"RuralZED, a new eco-friendly "flat-pack" house, costing 75,000, has been
designed by architect Bill Dunster of the Zedfactor. It is claimed that they
can be assembled by someone with no building experience, following a short
training course."


For those interested in solar thermal stores (maybe Nick in his Build It
Solar schemes could look at this), there is a good pdf on how the innards
http://www.consolar.co.uk   Go to the thermal stores and download the pdfs.

If one is worried about stratification in the thermal store being
compromised then isn't it easier to have 2 solar return ports on the storage
tank, one 1/3rd up from the bottom and the other 2/3rds. A 3 port solenoid
changeover is used to direct the returning heated water to either of the 2
ports depending on the water temperature. If the returning water is 20-30
degrees (Celsius here in NZ) lower than contained in the tanks top then send
it to the lower port etc. At least thats what my system does and works fine.
It follows a taller tank has better stratification than a shallow one.

That is one method, by just diverting water to differnt sections in the
cylinder.   A temperature differntial controller ca do the same thing, then
if solar heater water is hotter enough it is pumped right to the top.

The Consolar does it all mechanically with no moving parts and automatically
too.  Much better.  But this has to be built into the cylinder.  Using
tappings on the cylidner, a diverter valve and temperature controllers, it
can be DIYed, which is also great advantage, as cost is reduced.
