the first one is to buy famous brands.

in today's solar energy industry, the quality and after-sales service of brand-name products are guaranteed. However, if consumers want to choose through their own observation and comparison, there are some difficulties. For example, the key components of a solar water heater are the insulation of the water tank and the material and thickness of the steel in the tank. Only after the water tank is destroyed can the thickness and material of the tank be determined. There is also the quality of vacuum tubes, which even people in our industry can't identify without destroying products and using precision instruments.

but once the quality is unqualified and damaged, it cannot be repaired. For example, if the water tank liner leaks, it is necessary to find the leakage point, completely destroy the end cover of one end of the water tank, dig out the insulation layer, weld it with argon arc welding, re-foam it with polyurethane, and then find a new end cover to buckle it. After a toss, the cost is similar to buying a new water tank and changing it, and the welding place will not last long.

so, it's much easier to buy famous brands, but the price is more expensive.

so what is a famous brand?

The honor gold content of solar water heaters from high to low are "China Famous Brand", "National Inspection Exemption" and "China Well-known Trademark".

let me recommend some real famous brands to you!

China famous brand products announced by the General Administration of Quality Inspection and Quarantine, only seven companies have been selected for the whole solar water heater industry. As follows:

The quality of these products is not bad. Your question is cost-effective, which is the highest? This mainly depends on the pricing of local dealers, and some require low profits and cheap prices; Some demand high profits, and the price is expensive. In this way, I will divide these products into three grades, six grades and nine grades, and give you a quality reference. You can go and bargain bravely with the dealers.

The best: Tsinghua Sunshine (except the fast music series), Huangming, Linuoruite, Yi Canon and Tianpu.

General: Sun Rain (Four Seasons Muge), Huayang, Qunsheng, Brilliant,

Poor: Sang Le. Disclaimer: I am not an employee of any of the above companies. Our products are OK, and the price is cheaper than theirs. We don't know if our retailers have them.

Another way is to ask neighbors, relatives and colleagues what brands they use. If they have used them for more than three years, they can buy them, whether they are famous brands or not.

There are a few suggestions for you:

1. Don't listen to the bluff of dealers and promoters. This "three highs" and that "heat insulation wall" are all making gimmicks. In recent years, there is no breakthrough technology in the solar water heater industry. The same is true of Sang Le's digitalization, which is actually a solar water temperature and water level meter. In fact, the failure rate of Xizi's water level meter may be lower. Also, a friend of mine in Jinan has only used solar energy from Sang Le for three years. Just after the warranty period, the water tank leaked, and the manufacturer was not responsible for looking for it.

2. Be vigilant to avoid buying counterfeit products.

Due to the low threshold of production and technology and poor supervision, the situation of mixed fish and dragons in our industry is more serious. Let me talk about several means of black sheep in this industry:

1) Being near colleges and universities. A few years ago, the rise of the phenomenon of playing Beijing brands and colleges and universities, in fact, most of them have nothing to do with colleges and universities. Registered trademarks are similar to those of "Peking University" and "Qing < P > Hua", and 99% of them are playing the edge of colleges and universities, that is, the trademarks are not registered at all, and the quality can only depend on your luck. Among them, I only know that the trademark "Tsinghua Sunshine" is a registered trademark, but at this year's solar water heater industry summit, it is very likely that the trademark "Tsinghua Sunshine" can no longer be used in the second half of this year.

2), beside the electrical brand. In recent years, there has been a trend of playing the edge of the electric appliance brand again. What is called "Haier Sunshine", "Gree Sunshine" and "Beautiful Sunshine" actually has nothing to do with other people's

big enterprises. It may be produced in their own yard by the couple plus seven aunts and eight aunts.

3), beside the industry famous brand. The banners such as "Hong Kong Huangming" and "International Huangming" are all fake. They are generally produced under the name of Hong Kong Huangming Company, but the trademarks are not Huangming.
