(Trouble brewing.. ;-)  What I have in mind is the following:

the jet pump) coiled on my roof. Boxed in on the sides, plexiglass above, but
open below. I have a tin roof and want radiant heating from the tin. (I'll use
metal studs and proper tin screws/washers to ensure a leak-free frame
installation.) A food-grade plastic barrel in the basement to store the heated
water, and a small pump to circulate the water slowly. A 30-60' coil of copper
in the barrel is the "cold water input" for the hot water tank. The roof coil
will be drained for the winter.


circulating from the same barrel as above.

parts of the house.

ducts as a heat-exchanger as well.

in the summer with the roof coils or not. But with the wood stove, it may be
possible at times to get the water to a boil. But perhaps I worry too much. If
the water's moving fast enough, it won't boil in the lines, and waste heat from
the wood stove won't bring a 60 gallon barrel to a boil, without burning the
house down first.


all the money saved in heating the water on the pump to move it.. lol)

I see that others have given good information on the solar portion of
this post, so I won't comment there.  I do, however, see a possible
problem with the wood stove part.  Chimneys must have a high
temperature gas flowing through them during updraft, or soot will
accumilate.  Once the soot does accumilate, you can be sure that soon
you will have a VERY hot updraft in your chimney, one that commonly
burns through the metal and ignites the house.  If you do cool the
gasses (heating water), I would recommend you clean your chimney and
flue area often.

: Hi All,

: I've been doing a bit of reading and am starting to think about solar
heating. (Trouble brewing.. ;-)  What I have in mind is the following:

: 3/4" black plastic hose (hard plastic that we use at the cottage attached
to the jet pump) coiled on my roof. Boxed in on the sides, plexiglass above,
but open below. I have a tin roof and want radiant heating from the tin.
