heat stores also use soil to store heat, but employ active mechanisms of solar
collection in summer to heat thermal banks in advance of the heating season
[14]. High temperature seasonal heat stores are essentially extensions of a
building's heating, ventilation, air conditioning, and water heating systems.
Water is normally the storage medium, stored in tanks at temperatures that
