The Universal Heat Storage System is an electric energy storage system used in the HVAC and hot water industry. It utilizes electricity during off-peak hours for energy, storing heat overnight and providing heating during the day. This equipment enhances the utilization of the heating storage system while reducing operating costs.

The heat storage system is a new energy-saving electric heating product introduced by Global Universe Company, in response to the power department's encouragement to use electricity for heating during off-peak hours and enjoy preferential electricity rates.

Development of electric energy storage during off-peak hours effectively overcomes the deficiency of large-scale energy storage. This equipment fully utilizes off-peak electricity for energy storage, flattens the peak and fills the valley, conserves electricity, reduces urban harmful gas emissions, and is an objective need of the times' development, as well as an inevitable trend for future development.

A thermal storage system, equipped with a thermal storage unit and auxiliary equipment, forms a thermal storage electric boiler system. During off-peak grid hours, the electric boiler is turned on to heat water and store it in the thermal storage unit. During peak grid hours, the electric boiler is turned off. Heat from the thermal storage unit is used for heating, achieving the goal of either fully utilizing off-peak electricity (full thermal storage) or partially using off-peak electricity (semi-thermal storage) for heating.
