This heat is stored and then used to heat water, which can heat buildings all year round. Sand batteries are effectively giant silos filled with around 100 metric tons of builder''s sand. This is used as the storage medium and is very effective in retaining heat for long periods. The sand can be heated up to 1000 °C or even higher.
