Mad, I'm not sure 5 gallons is going to help you much, it's not a lot of energy storage at any reasonable temperature.
Do the math, ( equation found here)
http://www.engineeringtoolbox.com/energy-storage-water-d_1463.html
E = cp dt m (1)
where
E = energy (kJ, Btu)
cp = specific heat capacity (kJ/kgoC, Btu/lb oF) (4.2 kJ/kgoC, 1 Btu/lbmoF for water)
dt = temperature difference between water stored and the surroundings (oC, oF))
m = mass of water (kg, lbm)

Trying to make power from alternative energy any which way I can.
Just to abuse what I make. (and run this site)

That I realize... That equation may or may not prove useful in my case, but I wouldn't even bother until I have the mega insulation done. I'll be picking up the pink foam tonight, along with some foam in a can, and see how that does.
