Yeah, that is why I do both... After my batteries are charged from my solar panels, my system auto magically flips a relay to my hot water heater and it heats my hot water. I have had to only use propane for back up for a few days.... Storing heat in water is indeed the way to go.

I made a video of my progress.... I have been tied up with gardening I may have more time this winter to move forward. This video is quality about sand battery storage -> This is my progress I have made with my sand battery...

I found someone else testing sand battery

Short answer it is lost heat at the moment, but I have run some tests with using it. I have used it to dry out wet wood before I put ifiber glass nsulation in, I put kindling on top of it that was when the temps were between 200 - 350 deg for like 6 hours.... so drying worked great. After put...

This is my latest experiment..... 2 1/2 gal pot filled with sand. On top of this is a stove top heating element powered by 3 260 watt solar panels in series. On top of this is a dutch oven about 1/2 gal of sand and a rail road rail about 12 inches long. all of this is in a trashcan...

The limestone cycle quicklime -> limestone and back again.

Here is another way this has been done, a rechargeable heat battery.. https://www.snappyheat.com/how-it-works.html sodium acetate CH3COONa - it's also the primary flavoring in salt and vinegar potato chips....

I have an idea that I have been working on. I want to store heat chemically in such a way that after the energy is stored I can release that heat months after I have stored the heat. I started thinking like this with Zeolite as this is a process that works, but getting a hold of zeolite is...

Chickens sure do take sand baths, but I would not advise it... The bacteria are not a factor as I am only using the water as a heat exchange. If I hooked this up to my home water system indeed it would be a factor one would consider.

Perhaps we might want to branch off into multiple threads? I think I might create a new thread for wood powered sand battery, or thermal mass heat storage.....

Now I want to measure temps with my laser probe on my sand canisters...... Sand does not have the cnvective currents that water does. thus the heat should not move out the same way..... Sand is insulation when dry it does make me wonder I wanted to run an experiment with mason...

So using nitrol wire to make a kiln may be a better choice.... The advantage would be for convenience for bending metal..... they are very handy if you want to put a bend in metal and not heat up the entire bar.

It is along this lines is what I was thinking.....
