How to identify the quality of solar water heaters


As we all know, Changsha solar water heater is a large piece of household durable goods, once you buy it home, it may not change for more than ten years. Therefore, you must choose the right one when you choose, in order to use it well. So how to distinguish the quality of Changsha solar water heater ? Today we will discuss this issue.

   Changsha solar water heater is composed of three parts: bracket, water tank and vacuum tube. The difference in materials, technology and process makes the service life of solar water heaters likely to be 3 years, maybe 5 years, maybe 10 years, or longer. From the perspective of family investment, it must be used as long as possible. . Then we must give priority to these aspects when identifying.

   First of all, let's take a look at the vacuum tube, which is the core component of Changsha solar water heater. Its function is to convert the absorbed solar energy into heat energy and heat and circulate the water inside the tube. The quality of the vacuum tube directly determines the performance of the entire water heater. By consulting the technical staff of the brilliant solar water heater (), we learned that the ordinary vacuum tube has low vacuum and short exhaust time, which causes the vacuum tube to not store heat for a long time. After being placed outdoors for a period of time, the thermal insulation performance is not as good as that of the thermos bottle.

Then there is the bracket of the solar water heater. The solar bracket is like the "skeleton" of the person. It is definitely not good to be weak. The traditional products use a thin rod bracket, which is thin and can not resist wind, and the brilliant water heater uses high-quality steel plate material, adopts advanced electrostatic spraying technology, anti-corrosion and durable, and uses the curved design of scientific mechanics. The overall performance of the bracket is improved, the bearing capacity is better, and the wind resistance, rain and snow resistance, hail resistance and corrosion resistance are stronger.

Finally, let's talk about the material of the water tank, mainly considering the following two aspects:

One is the tank of the water tank: the tank liner of the Changsha solar water heater has been working in the hot water environment for a long time, and the solar water heating project should have sufficient strength and durability. Inferior liner materials are not preserved, have insufficient thickness, and have low nickel content. They are easily rusted and cracked in hot water. Coupled with the backward welding process, water leakage is prone to occur. As the corrosion area increases, the liner is basically scrapped after a few years. The high-quality solar water heater adopts imported SUS304-2B stainless steel, which is corrosion-resistant, adopts argon-wool welding, has no intergranular corrosion, and has a long life.

The second is the insulation layer of the water tank. The insulation layer is the part between the outer skin of the water tank and the inner tank. The performance of the insulation layer directly affects the actual amount of hot water available for solar energy. Inferior insulation layer uses ordinary polyurethane, and even more uses plastic foam. Only some polyurethane foam is used in the bare place where the vacuum tube is inserted. After a few months, the heat preservation effect decreases linearly, and it is basically not insulated after one year. Ordinary polyurethane foaming equipment is simple, without high temperature curing treatment, using low pressure foaming machine or manual foaming, raw material mixing is uneven, heat loss is fast; without high temperature curing treatment, once the temperature rises, it will cause secondary foaming. Blow the outer casing of the tank and squeeze the inner tank. The brilliant solar water heater insulation layer is made of imported polyurethane, which is fully mechanically foamed. After high temperature curing, the insulation effect is special.
