I'd like to put a line of water-filled black plastic barrels in front of a
large window to save mid-day heat in the winter. A convenient size for the
space would be 30~50 gal, as tall and narrow as possible. Can someone please
recommend cheap sources for these? I'm trying to find used grape-juice
containers like home winemakers use, but they needn't be food-grade for
Also, is it best to add some kind of biocide to the water?
A related topic: these will go in a sort of greenhouse built onto the main
house, with one common wall. It's entirely uninsulated. I'd like to use it
through the winter, and can't really afford to heat it separately. I thought
of draping bubble-pack from wires or rods inside under the glass - awkward,
but easy to adjust. Is there a standard way to do this?

You might think about the following scheme for hanging the bubble wrap:
1) cut a piece of bubble wrap to the size of the glass pane to be
2) spray or sponge the glass surface with plain water until the
surface of the glass is wet.
3) apply the bubble side of the bubble wrap to the wet
In my experience, the bubble wraps will stay up until you pull it
down. It is easy to take down for the summer, and you can save the
pieces and use them for several years.

That insulates the windows. It doesn't store heat from solar gain.

I was just trying to answer Theo's 2nd question where he talks about
"draping bubble-pack from wires or rods" for insulation, and is
looking for a good way to do this.
