What's the difference between Haier electric water heater ES60H-D3(E) and EC6002-R?

The letters in the model are used to distinguish different series of products. EC is a product sold through e-commerce channels, and ES is sold through offline channels.

ES60H-D3(E) is sold in physical stores and EC6002-R is sold in e-commerce. Different distribution channels have basically the same product functions. All of them have patented electricity-proof wall technology and delayed appointment function, and the three-speed power can be adjusted. The two operation modes are machine control and remote control, which are first-class energy efficiency and high cost performance.

These two kinds of water heaters have different shapes, but their functions are basically the same. The models are different because the sales channels are different, so the models are different.
