Founded in 1991, Huayang produced the first vacuum tube and the first vacuum tube solar water heater in East China, and launched the first automatic water supply solar water heater. He is currently the chairman unit of China Solar Thermal Utilization Industry Alliance, and has participated in the drafting and formulation of national solar energy standards for many times. Huayang has more than 240 patented technologies, and its products are sold to more than 30 countries and regions such as the United States, Russia, Germany, and Italy. Huayang's pressure-bearing integrated system has passed the EU Solar Keymark certification, and it is also the first enterprise in China to obtain this certification. In 1998, Huayang launched the first automatic water supply solar water heater, and now automatic water supply has almost become the standard configuration of solar water heaters.
 
The top of the glass vacuum tube solar water heater needs to be connected to the atmosphere to ensure that the hot water can flow naturally through gravity, so this type of product cannot withstand pressure. This design is simple and low-cost, but it also brings many problems to solar water heaters. For example, the solar water heater needs to be more than 7 meters above the shower to ensure that the water flow of the sprinkler head is large, and the water pressure of the penthouse will be obviously insufficient. In addition, because the atmosphere is connected, the warm water in the tank and the atmosphere can achieve material exchange, providing a good environment for bacteria to multiply, and the water quality is poor, so the hot water in the solar water heater is not suitable for kitchen use. Huayang is the only brand that has launched a glass tubular pressure design product, which allows the water tank to maintain the tap water pressure and maintain a large water supply volume.
 
Huayang's villa pressure-bearing all-in-one machine has a pressure-bearing top water operation system, which does not require additional pressurization devices to have a good water effect. There are two options for capacity: 170L and 200L, and the prices are 7,000 yuan and 7,800 yuan respectively. In addition, this series is the only one of many water heaters with a stainless steel bracket, which greatly enhances corrosion resistance and wind resistance.
 
In addition to the pressure series, Huayang's glass vacuum tube products are divided into classic series and steam core series. Each series can be divided into three types: manual water supply, automatic water supply, and electric auxiliary heating automatic water supply, and the latter two are increased by 300 yuan and 400 yuan on the original basis. Automatic water supply saves time and effort, while electrically assisted heating provides hot water on rainy days, which consumers can purchase according to their needs.
 
The steam core series is named after the use of steam core vacuum tube, which is a unique three-target tube of Huayang, and the water is replaced by gaseous refrigerant in the tube, which will not scale and freeze crack. In addition, the vacuum tube adopts a variable frequency coating layer, which absorbs the heat of natural light in the whole wavelength and makes full use of the heat. The inner liner of the incubator is made of POSCO 304 stainless steel from South Korea, which avoids the problem of water leakage in the circumferential welding. In terms of the electric auxiliary heating system, it is equipped with an external leakage protection plug to automatically cut off the power supply within 0.1 seconds to fully protect personal safety.
 
Huayang solar water heater focuses on technological innovation, practical products and rich choices. The warranty time is 5 years.
