Thermal energy storage systems are secondary energy storage systems that store heat. They can be grouped by their technical use: • Sensible heat storage systems store energy with a medium change in temperature before and after charging, which can be "sensed." This is multiplied by the heat capacity and mass of the medium to determine the amount …

A heat storage system allows a indoor wood boiler to operate continuously in its most clean and most efficient state. Heat storage captures and releases heat like a battery, so the boiler needs to be loaded less often. These systems use insulated hot water storage tanks or buffer tanks — which function similarly in this context — to hold onto generated heat …
