That is why the energy-saving water heater
The water heater storage water heaters than traditional power, which is industry-recognized, but the market, the consumers of this energy-saving products have become very fond of him, reporters found that there is only a very small number of consumers buy the product.
The water heater not warm up in advance, so there is no preheat thermal energy dissipation. When used to open, not shut down, how much water to put much water, so there is no more than storage water heaters heat water consumption. In addition, boot to it from the water temperature reaches 45 ¡æ heating time of only 30-40 seconds, and truly save water and power. According to the development of this water heater expert, senior engineer Xu Guohui on Haihuai Si's introduction, although the water heater's rated power of 3.5 kilowatts -6 kW, but according to the law of conservation of energy, power does not mean that energy consumption , compared with other water heater or the most energy efficient because it uses the least time (power ¡Á time = energy). "I spent nearly five years of the water heater, after numerous tests, by Nanchang, Shanghai's actual use throughout the year and found that it is more than storage water heaters saving 40% -65%." Xu Guohui said.
Water heater manufacturer billion Canon had specifically been tested in Beijing, 40 l insulation the better storage water heaters, hot water 24 hours a day that do not, but also consumes more than 1.2 degrees, and colder power greater. In contrast, the electric water heater, of course saving more.
This product is said that consumers should be saving the rush is on, but Beijing is a small home appliance chain store appliance department manager told reporters: "On the contrary, the water heater is not good marketing, not just 2000 yuan hesitant about the price to consumers, the key issue is the environment of electricity average family can not use it. "
¡ñ security "longevity" failed to interest manufacturers
The water heater is not easy to furring, longer life expectancy, but also can avoid water pressure start, that is, as long as the water flow can be started. But the reporter learned through the investigation, some well-known home appliance companies are not interested in it.
According to reports, the water heater cold water through the heater is heated directly, are "living water", it is not easy to scale, while the hot water bath temperature is generally no higher than 45 ¡æ, which are also in the pipeline difficult to form scale, again, that the water heater in the heating process of heating the machine is not very high body temperature rises, water and heating so the failure rate will be reduced accordingly, so that the water heater's life are more long storage water heaters, storage water heaters are generally 2-3 times.
The water heater can be achieved another major advantage is that water pressure-free start, Batch Control Meter as long as the water flow can be started. Generally speaking, gas water heater pressure in 0.02Mpa start over, a number of high-rise building water pressure, gas water heater will not start.
The water heater there are so many advantages, but many well-known consumer electronics companies are not interested in it, Hale said did not think of this product, Ariston also said the development of this product has been tepid, to promote not a problem, some of its own conditions of use is difficult to determine the market grow.
¡ñ The problem is the electrical environment card "neck"
Experts believe that consumers and some manufacturers are not interested in the fundamental reason lies in that the water heater's power rating, the highest reached 7 kW, the minimum should be 3 kW, and so much power on the consumer's home electrical environment has special requirements. Such as the power cord requirements, at least in cross-section of 2.5 mm2 or more, and some require more than 5 mm2. In addition, the "civil design specifications" JGJ/T-16-92 standard is to enter the residential electricity capacity is generally only reach 5 kilowatts -6 kW, that is, with the instantaneous electric water heater, home air conditioners, the refrigerator would have to turn off the electrical category, except replace the 40A meter, of course, have to change wires, while the general residents of the home meter is only 20A.
The reality is that consumers are a little difficult for the water heater replacement meter, wire, so consumers that the water heater's attitude was "not easy to say love you", naturally it is difficult to interested companies .
Despite the current electricity constraints of the water heater's development, but there are still people in the industry is optimistic that its prospects remain good, according to Europe 20 years ago it was gas storage water heaters and water heaters dominate the world, but 20 years later, the water heater have occupied more than 80% market share; the next 10 years China will have 33% of households moved into new houses, which means an annual average of more than 2.6 million water heaters to replace old ones, and the electrical environment of new homes will be much better than the existing houses, so that the Heating Meter water heater of the future is really good. As consumers, we may also wish to wait and see.
