Advantages and disadvantages of solar water heaters

Every time we get to the winter, we will hear about many solar water heater related accidents. Is solar water heater really so unsafe? Does it really affect people's life and health? In fact, this is not the case. In the use of solar water heaters, we must keep a mind and grasp the relevant precautions.

Advantages and disadvantages of solar water heaters

Solar water heaters are really good. When the air energy water heater is in the winter-10, its energy efficiency ratio is very low. You have to choose a professional air energy brand. If you want to achieve an energy efficiency ratio of 200 or higher, you should choose a suitable north. The brand that runs, but the annual energy efficiency ratio of air can reach more than 400. Air energy is an active heat absorption, while solar energy is passive heating. When there is no sun, it needs electricity to directly heat the hot water. Running air in the whole year can save more than one-third of the electricity compared to solar energy.

What are the advantages of solar water heaters? It is a high-tech product, copper-aluminum anodized composite core or full copper core, high surface treatment process, good heat transfer performance, strong heat absorption capacity, large water production; fully automatic solar water heater system Static operation, no need for special care, no noise, no pollution, no leakage, fire, poisoning, etc., safe and reliable, environmental protection and energy saving for the benefit of the country.

However, solar water heaters need a full day of sunshine to heat the water. When the weather is good, it can only guarantee hot water at night. There is very little hot water available during the day and night. It can not guarantee the user's 24-hour hot water supply and comfort. In addition, the lighting panels of solar water heaters must be installed on the roof, which is bulky and bulky, and affects the aesthetics of the building (the more obvious the high-end residential area), and it is easy to damage the roof waterproof layer.

Solar water heater considerations

Note for solar water heaters: The water that is just picked up by the solar energy is generally the water in the pipeline. The temperature at the beginning is not high, but the water temperature in the solar water heater can reach 90 °C or more in the summer, and the cold water in the pipeline is exhausted, more than 90 degrees. The hot water will rush out, and the user will often be burnt if he does not pay attention. When you just put the water in the bath, you should notice that some of the cold water stored in the water pipe is released first. Once the water in the solar water heater flows, the temperature will suddenly rise and cause burns.

Note for solar water heaters: When the weather is extremely hot and the water temperature is extremely high, it is strictly forbidden to add water immediately after the water is used up, because the water is easy to cause the pipeline to burst. The best watering time for solar water heaters is two hours before the sunrise in the morning or in the evening, so that the life of the solar water heater can be guaranteed.

Note for solar water heaters: Check the vents regularly to ensure smooth flow, so as not to damage or sample the water tanks; solar water heaters with auxiliary electric heating devices pay special attention to water supply to prevent dry burning.

In order to avoid the occurrence of a misuse of gas water heaters, a series of hazards. In normal times, when we purchase a gas water heater, we must purchase a brand-guaranteed product. At the same time, we should pay attention to the above-mentioned introduction of the use of gas water heaters in the use of gas water heaters.
