Where do you intend to store that much liquid?

I thought I wound put it under the basement floor. 6" of insulation
surrounding the tank.
Yes, Nick, I know what NREL says. I can't change the fact that this
she dormer will only be 20% sloped. Better than nothing.
Nick. Do you think aluminum will outperform a steel trickle collector.
Man, I am having a bad time finding some aluminum siding.

I thought about burying a polyethylene tank 1600 US gals in the ground but not
sure how I would insulate it cheaply.
Possibly a concrete crypt and a poly tank in the middle stuffed with insulation/
styrofoam and gravel ouside the crypt but it is all starting to sound rather
expensive to save a few hundred dollars per year in fuel for hot water.

Found a plastic tank, 4,500 gallons for $500 bucks. Building my house
out of SIP panels, a fantastic suggestion from Nick. The folks are
going to give me the insulation for real cheap.
If you look around, possible to by big logs of EPS that you can cut
for cheap Like 4'x4'x20' etc for a hundred bucks or so. Cut with a hot
wire, that will go a long way.
I thought about a variety of ways to build this heat storage. Still
looking for the cheapest, most durable, etc. I think it will be hard
to beat this big old used, plastic tank.
Thought about insulating a big trench 8'x'8'x20' and filling with rocks
and having a long, big utility pipe in the middle maybe 4' diameter
(fiberglass or Corrugated Galvy) and wrap with copper or run copper in
the middle. Many different ways to skin this cat.
A big ferocement tank looks really cool as well.
