Sunrise East is the only listed company in China with solar thermal energy, and Muge is its flagship brand. As a technological vane for the entire solar industry, every innovation of Four Seasons Muge is an emulator for industry brands, and its signature vacuum tube durability technology is still unique today.
 
As a core component that has been exposed to the sun and rain, the vacuum tube not only needs to resist external hail and dust, but also delay the oxidation of the internal material. The vacuum tube of Four Seasons Muge adopts ATO antioxidant technology, which can prevent the diffusion of molecules between different functional layers, effectively delaying the common problems of decoating and fading, and other brands have not yet launched similar functions.
 
The one-sided exhaust hole of the water storage tank of the solar water heater with a long service life is often blocked by dust, poplar flowers, fallen leaves, etc., resulting in hidden dangers such as deformation and deflating of the water tank, and the situation in Hebei and other places is particularly serious. In view of this, the new products launched by Muge in recent years have replaced the traditional single-hole exhaust on the side with an umbrella-shaped porous exhaust design to increase the durability of the product.
 
Four Seasons Muge products change rapidly, there are many series, the letter series is the early classics, the most representative of which are C series, O2 series, C double cabin series. Later, Siji Muge launched the "Fine Diamond Aerospace Tube", which adopted the patent of "Photoselective Absorption Layer and Its Preparation Method", which improved the heat collection performance and durability compared with the ordinary three-target tubes of the past letter series. 15 years later, the products are basically equipped with such space tubes, and the series is also run through the word "aviation", the more classic series are the aviation flying spur series, the aviation aurora series, the aviation Yuedong series, the aviation lightning series, the aviation galaxy series, these aerospace series compared with the past product price increased by about 300-500 yuan, but the durability has been greatly improved.
 
C series is the most common solar water heater offline, and it is also a product that is often recommended for offline purchases, but the series is not as economical as it seems, the function is slightly weaker, and the price is 4500 yuan - 8500 yuan. One of the major advantages of this series is that as an offline classic, even if you choose to buy online, the local proximity delivery can be extremely fast to the door, greatly reducing the waiting time, while the online purchase of the aerospace series can only wait for the manufacturer to mail. Consumers can buy according to their urgency, and the best way to buy is to go to a local specialty store to buy on-site.
 
There are many aerospace tube products, and the differences are often subtle and subtle. The price of the Flying Spur series is 3700-6200 yuan, which is the basic model of the economy. The series is available in 140L, 155L, 180L, and 220L capacities, and the product can be selected according to the number of people in the family and water consumption. The price of the Hang Yuedong series is lower, 400 yuan cheaper with the same volume, and the function is the same as that of the flying spur, and many consumers will buy this series of products. However, it must be reminded that the product does not provide installation services, and consumers who do not have technical capabilities should not buy impulsively.
 
Aviation Aurora series is the top product of Four Seasons Muge, the volume of the water tank has been increased by nearly 20L compared with before, the stainless steel liner is used, and the thickness of the bracket steel has also been greatly improved. The water heater bracket of various brands of products often adopts a "Λ" shaped side design, which is relatively economical in steel, and this series adds a horizontal bar to make the bracket present an "A" shaped structure. The design is simple, but it's the finishing touch, and the triangular structure greatly enhances the stability of the stent. For areas with many typhoons along the coast, priority can be given to this series of products. The price of the product with a capacity of 160L in the Aurora series is about 4800 yuan, and the price of different e-commerce platforms fluctuates greatly, and the gap is even 500 yuan.
 
The above products are all vacuum glass tube solar water heaters, which are also the most common type, accounting for about 98% of the market share. This type of product has a simple structure, high cost performance, extremely high solar energy utilization, and the gap is also conducive to wind resistance. However, this type also has some inherent shortcomings, such as it can only be installed on the top floor and is not suitable for urban unit housing, it cannot be operated under pressure, resulting in the water pressure depends on the height difference, and the water output is very small when the drop is less than 7m, and the water cannot be stopped and dried in the air. When many consumers buy water heaters, they are often discouraged by solar energy for these objective reasons, and in order to solve such problems, flat panel solar water heaters came into being. Flat plate water heaters can withstand the pressure of tap water and can be installed in non-top houses, which is the new development direction of solar water heaters.
 
Four Seasons Muge has launched two flat products, OP-B wall mount and Jinlongxing. Among them, the OP-B wall mount adopts a split design, and the heat collector plate absorbs solar energy outdoors to heat the heat conduction medium, and the heat conduction medium circulates through the pipe to heat the cold water in the indoor wall-mounted water storage tank. The heat collector plate outside is easy to install, can be directly fixed on the wall, and the water storage tank is similar to the structure of an electric water heater, which unifies energy saving and ease of use at home, but the small capacity of 100L is more suitable for small families with little water demand, and the price is about 5700 yuan. Jinlongxing adopts the integrated design of water tank and heat collector plate, which reduces the heat loss of the medium in the pipeline during the circulation process, but also leads to the fact that the model must be placed on the roof, and the wind resistance of the plate is poor, and there is a hidden danger of being overturned by the wind. It is not recommended to buy this all-in-one product of about 6600 yuan.
 
In terms of after-sales service, Muge is relatively weak. Four seasons Muge and dealers at all levels adopt a "buyout distribution" method, "pay first, then produce, and then ship", after-sales service is responsible for the stores around the country, there is no special after-sales maintenance team, so its after-sales service is often criticized by consumers in some areas. However, this problem can be said to be a common problem in the industry, and brands such as Huangming and Sangle also use similar after-sales outsourcing services, which are directly linked to the local service level. All solar products of Four Seasons Muge adopt a three-year warranty policy for the whole machine, which is slightly shorter and is downstream of the industry.
