Solar water heaters are high-tech products and their working environment is very harsh. They are exposed to wind, rain and high temperatures all year round. round, so they have very high quality requirements. The solar energy market is complex and complex. Consumers should keep their eyes open when shopping to avoid being deceived and suffer losses, and to protect their own rights and interests while enjoying the comfortable life provided by nature. Therefore, experts remind consumers to learn to use the "four looks" method when purchasing solar water heaters, so that they can feel at ease and at ease when use them.
1. Focus on capacity, but more on “heat gain”
When promoting solar power, some manufacturers blindly putfocus on the capacity of solar energy, thinking that the larger the capacity, the better. In fact, larger capacity does not mean more hot water available. When it comes to solar water heaters, the most important thing is their thermal efficiency, i.e. “heat gain”. It refers to the actual total available heat that the water heater obtains from sunlight over the course of a day.
2. Focus on the present rather than the long term
Although solar water heaters are large, durable goods, manufacturers release new products every year, and consumers do not probably don't buy it every year. Therefore, choosing a solar power product with excellent performance and advanced technology is a wise choice for consumers, so as not to enter the product replacement period prematurely. At the same time, even sAlthough some solar water heaters available on the market can meet the demand for hot water in summer, they remain unused in winter. Because in the low temperatures and weak sunshine in winter, the original heat-absorbing materials cannot play any role, and these "problem products" have long had cracks in the tubes. Experts believe that purchasing a solar water heater with larger capacity and advanced performance will be more cost-effective in the long run.
3. Pay more attention to price than strength
Price is certainly important to consumers, but choosing a trustworthy brand and reducing purchasing risks is even more important . . So don't let the price fool you. A number of irresponsible companies are adopting shoddy methods to produce low-cost products that are equivalent to "problem products" with apoor quality, poor service and poor performance. Water heater collapse, leaks, lack of hot water and other phenomena common in the market are all root causes of this type of product. Therefore, a credible brand has become the best choice, and its excellent quality and strong after-sales service will guarantee the legitimate rights and interests of consumers. If you choose to enter the market for speculative reasons and quickly withdraw from the manufacturer's products, your after-sales service will not be guaranteed.
4. Pay more attention to what is visible, but more to what is invisible
To ensure that the solar water heater works well in a very harsh environment. outdoor environment, raw material selection It deserves everyone's attention, not only the quality is good, but also durable. At the same time, the performanThese invisibles, know-how, technology and after-sales service are more critical. Experts believe that products such as solar water heaters are expensive and will cause problems if they break down, consumers cannot repair it themselves, and the cost of parts is also high. Therefore, a guarantee of reliable and high-quality service should become another major factor in the purchasing decision.
