How many years does Huangming solar energy last?

Introduction How many years does Huangming Solar Energy usually last? Although many brands claim that their products have a lifespan of up to 15 years, they are usually disposed of after 10 years of use because the lifespan of the heating tube is only ten years.

How many years does Huangming solar energy last?

Although many brands claim that their products have a lifespan of up to 15 years, they generally need to be disposed of after 10 years of use, as the lifespan of the heating tube is only ten years. years, the safety factor will be reduced and the risk of electric shock will easily occur. In addition to the limited life of the heating tube, the "short life" of solar water heaters is due to the following reasons:

1. Vacuum Tubes

Vacuum tube is the main component of solar water heater, and its quality directly affects the overall performance of solar water heater, the quality of vacuum tube is affected by the technology of coating and processes such as cleaning, coating, vacuuming and sealing. Inferior vacuum tubes have low vacuum degree, poor film stability, and are prone to aging and falling, resulting in rapid attenuationpoor heat collection performance and an inability to absorb sufficient heat.

2. Insulation layer

The thermal insulation performance of the solar water heater is determined by the quality of the insulation layer. A good insulation layer has uniform foaming, high density, low thermal conductivity, high temperature resistance, high thermal insulation performance, and is stable and durable.

3. Coating

The coating is the most critical component of the solar water heater. Good solar water heater manufacturers use titanium porcelain coating, which is durable and has strong anti-corrosion properties. . Inferior-quality coating, such as stainless steel coating, has poor pressure resistance and is easily corroded by scale, causing the water tank to leak and affecting the life of the solar water heater.

Durationlife of qualified products is 15 years;

What to pay attention to when purchasing:

1. Vacuum tube

The vacuum tube is a solar water heater Essential components, solar energy currently in the building materials market is mainly divided into thick tubes (generally 58mm in diameter) and thin tubes (generally 47mm in diameter). Relatively speaking, thick tubes have a large heat collection area, fast heat collection and high water temperature. Therefore, when purchasing, priority should be given to solar water heaters using thick tubes.

Vacuum tube materials mainly include single target machines and three target machines. The quality of three-target machines is better, and consumers can identify it by appearance when purchasing. The vacuum tube of the single target machine is gray in color, with color difference, andthe inner wall of the vacuum tube is light black, while the vacuum tube of the three-target machine has a bluish appearance, no color difference, and the inner wall is dark red.

2. Water tank weight

The water tank is very important for solar water heaters. Generally, heavy water tanks are of good quality. The weight is mainly determined by the material of the water tank shell and the foam layer between the water tank shell and the water tank liner. Typically, the shell of a mediocre water tank is made of shiny stainless steel. It is not thick enough and is light. The foam layer is directly related to the insulation effect of the water heater, so it is also very critical for the use of the water heater. Generally, the foam layer of famous brand products is foamed by machine under high pressure, so that there is no air between the outer shell and theinner tank, and that the foam layer is dense and thick. Therefore, the entire water tank is often heavy to weigh.

3. Bracket Material

Generally, the brackets of better quality solar water heaters are mainly made of aluminum alloy brackets, which are thick and strong.
