About High energy storage heating

Thermal energy storage (TES) is the storage offor later reuse.Employing widely different technologies, it allows surplus thermal energy to be stored for hours, days, or months.Scale both of storage and use vary from small to large – from individual processes to district, town, or region. Usage examples are the balancing of energy demand between daytime and nighttime, storing s. A storage heater, also known as a night storage heater, is a type of electric heater that usually makes the most of off-peak electricity. It spreads the heat around the room using what's known as convection currents. As the hot air from the heater rises, it pulls in cooler air. In turn, this gets warmed up by the heater.
