What about the stainless steel water heater in Dong Qing?

Many of our relatives use stainless steel water heaters in Dong Qing, because my sister's family installed stainless steel water heaters in Dong Qing, and has been engaged in various Amway at home. Later, when my family planned to replace the water heater, it was also installed in Dong Qing. The experience is really good and the constant temperature function is very good. When taking a bath, the water temperature will not be hot and cold, and it can be adjusted to 30-60 C. Specifically, water should not be too hot in hot weather.
