text: Warm-temperature seasonal heat stores can be created using borehole fields to store surplus heat captured in summer to actively raise the temperature of large thermal banks of soil so that heat can be extracted more easily (and more cheaply) in winter.
text: As seen in the therein Ground Loop and Ambient Air temperatures by date graphic (Figure 2-7), one can easily see the annual cycle sinusoidal shape of the ground temperature as heat is seasonally extracted from the ground in winter and rejected to the ground in summer, creating a ground "thermal charge" in one season that is not uncharged and driven the other direction from neutral until a later season.
