CHARACTERISTICS

Optimized design

The special of this new type solar water heater is inner tank which designed with two independent inner tanks, this product is a national patent.

Automatic feeding water

Adopted an assistant tank to stop feeding when the tank is full of water, otherwise automatic feeding while the tank is lack of water. This solved the problem of not work with a sensor controller sometimes. Automatic feeding water is better than feeding by a sensor controller, no need of looking after.

The way of hot water outlet

Designed with two independent inner tanks which insulated by polyurethane, the bottom cold water in the big inner tank pushes the hot water into the small inner tank, then the hot water outlets from the upside of the small inner tank, thus the hot water in the small inner tank will be more and hotter. This special design improves the efficiency of outlet water, separates cold water and hot water to improve the using of hot water, and avoids the water sometime cold and sometimes hot.
