|Merging Thermal Storage with Load Shifting for Efficient Cooling

The theory behind load shifting is to use more power when it’s cheap and less power when it’s expensive.
The overall system costs are quite low. The insulated holding tank is just a re-used water heater tank, and the thermal battery tank is a store-bought cooler priced at $80. The off-the-shelf copper coils were priced at $20 apiece, and the small circulating pumps each cost around $50. The total cost of the sensors, the Barionet, and the MBus_Io10_LCD is under $350. The WattNode demand meter and the water meter are optional components and economically priced.
