Thermal energy storage (TES) is the storage of thermal energy for 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…

Lower energy efficiency: Storage tank water heaters constantly heat and store a large volume of water, leading to standby heat loss. This can result in higher energy bills compared to tankless water heaters. Shorter lifespan: On average, storage tank water heaters have a shorter lifespan of about 10 to 15 years.
