Commercial Hot Water Engineering

Generally applied to centralized hot water supply units such as hotels, hospitals, schools, and factories that share hot water. In terms of solar collection forms, it is divided into vacuum tube type and flat plate type, with vacuum tubes further categorized into heat pipe pressurized collectors and non-pressurized types. 

This technology belongs to the same category as the above. If it is for a single unit using hot water, separate metering is not required.
