Advantages: high safety performance and clean energy. Can supply water in multiple ways. It can be used for showers, baths, laundry and washing. Installation is also simple and easy to use.
Disadvantages: Generally, the volume is large, and it needs to be preheated before use. It is not possible to continuously use the amount of water exceeding the rated capacity. If there are many families, the bath must wait in the middle. In addition, the hot water that has not been used up after washing will slowly cool down, causing waste. The water temperature is high in heating temperature, easy to scale, and the dirt cleaning is troublesome, which is unclear and affects the life of the heater.
