HydroThermal Energy
Renewable energy using water as a heat source for heating and cooling through heat pumps, utilizing the seasonal temperature difference between summer and winter.
※ Water has a high heat capacity (specific heat: water 4.18, air 1.01 J/g.°C).
※ Supported sources include river water, dam water, tap water, and surface seawater.
