Hi,

I thought this was a pretty interesting solar hot water heater.

http://www.hotharry.com/default.htm

It is a horizontal pond of water contained in a rotationally molded PE
casing.  Glazing is two layers of glass with a honeycomb material
between.  The supply pipe passes through the pond to pick up heat from
the pond.  The prices seem high to me given the relatively simple
construction.  The "How It Works" link shows the internals.
Its a bit over 6 ft by 4 ft.  The total depth of unit is 9 inches, so
the pond is probably about 6 inches deep.  There only appears to be
about 25 ft of copper pipe passing through the pond to act as a heat
exchanger.

It is somewhat similar to the less fancy (and MUCH less expensive) one
that I described here a month ago, that lives at:

About half way down the page.

This pond in most homes would be in the way.  Having it on a flat garage
roof would seem a better location.

What a lame-ass excuse :-) You might as well say that it's ugly,
or that a swimming pool or a garden or a garage is "in the way."

Still in the way and people could fall or walk on it.  On a flat roof is
best. - ideal.  And it is ugly.  Some psychedelic paint may improve it.

I suppose there are pros and cons to ground vs roof no matter what
kind of solar water heater it is.
I think the ground location makes it easier to build, eliminates the
possibility of falling off the roof while installing or servicing,
makes it easier to have a reflector to improve performance, and makes
it easier to brush the snow off.  While the roof one frees up a little
yard space, and might get a more sun in some cases.
I guess either way works :-)
