If I understand this thread correctly, the point is that Nick is
suggesting demonstration units to show that solar heating works in
places where most folks don't believe it will.

My suggestion is that if you want people to believe they can solar
heat their houses then a demonstration house is what they could
easily understand. Lots of folks make portable structures on wheels
for construction shacks and the like. Make your demo built on such
a trailer, give it the look of a small mobile home with carpeting
and a couch and let people walk through it. Maybe you could let them
sit for a while and watch a recorded TV presentation inside.

Then again, perhaps this is all overkill. If you want to convince
folks that they can heat with the sun then maybe all you need is
a solar air heating panel. Set it up outside so it vents hot air
at a single spot where people can warm their hands on bitter cold
days. Place a clear and very simple diagram with details about how
the panel works next to the thing. Put it in places where people
are going to be cold and standing around.

  I tried to convince someone you could solar heat a house and they
asked "where has this been done?" I explained that in the US most
solar heating is for hot water and pools, but I read that up to 40%
of the solar heating was used to heat homes in Europe. If I had just
one example to show that person of an average house that was solar
heated, I think that they would have been convinced.

In some areas (NY for example), there were a lot of folks 'burned' by the
solar-heated home craze in the late '70's.  So the building code now
requires a high burden of proof that a home is solar heated exclusively.
Otherwise, it must have a more conventional heating plant that is large
enough to fully heat the home.  What a seller might consider 'solar heated'
may mean to the buyer, 'solar heated if you like to wear sweaters a lot and
enjoy 50-60 degree home'.

So, building a home in one of these areas means you pay the 'up-front' costs
for two heating plants, the conventional one required if you ever want to
get a building permit, and the solar one to save energy/planet.

Solar 'boosting' or 'supplementing' is a lot more appealing to many since
the solar plant doesn't have to be as large, and you still get some of the

But a major factor to a lot of folks is, "How will this affect my resale
value?"  If the average buyer and the bank don't agree on what you think is
the increase in home value, you may have a 'white elephant' on your hands.
Until the public at large (including mortgage companies) start to see the
true value of such systems, you may be better off just tearing it down when
it comes time to sell.
