Hot water storage | EHI

Storing hot water is a good means to store energy, as water accumulates a lot of heat per unit of weight. A hot water storage tank can help reduce energy consumption as it takes less energy to keep water warm (once it has already been heated) than it takes to heat cold water. Hot water cylinders can also help provide demand response services to ...
