Design Considerations for Borehole Thermal Energy Storage (BTES): A Review with Emphasis on Convective Heat Transfer

Figure 11

(a) The density of water and its dependence on temperature—based on data from [67, 68]; (b) from this data, it is possible to calculate the excess height of water column caused by heating an 80 m column of water by +4, +10, and +20°C, respectively. The blue lines show the height decline caused by cooling the water column.
