What does solar water heater engineering machine mean?

The engineering machine is used in solar water heating projects. Suitable for unified management of hot water systems in units, hotels, communities, etc. In order to distinguish it from domestic machines. The structure and principle of engineering machines are completely different from those of domestic machines. Engineering machinery typically consumes at least more than 2 tons of water per day; domestic machines generally have the largest capacity of only 500 L; the domestic population is small, so there is no need to use engineering machinery.
