Here's a way to store heat from renewables .... Could be used and is cheap... ... %20heating. ... en-energy/

This could also be heated with solar or any other energy that is available.

You could also use off peak electric to heat the sand. It is much more economical to store energy as heat rather

than electric especially if the final use is as heat anyway.
