    FAQs about The temperature difference inside the energy storage container produces water droplets

    What determines the heat content of a hot water store?

    The heat content of the hot water store in a specific temperature interval from Tmin to Tmax is determined by the product of the heat storage capacity and the temperature difference (Tmax – Tmin).

    What are the thermal characteristics of a hot water store?

    The most important thermal characteristics for hot water stores are: heat storage capacity, heat loss, heat exchange capacity rates to and from the hot water storage and temperature stratification in the hot water store.

    How does a thermal energy storage system work?

    A typical thermal energy storage system is often operated in three steps: (1) charge when energy is in excess (and cheap), (2) storage when energy is stored with no demand and (3) discharge when energy is needed (and expensive).

    What is hot water storage & how does it work?

    As with chilled water storage, water can be heated and stored during periods of low thermal demand and then used during periods of high demand, ensuring that all thermal energy from the CHP system is eficiently utilized.
