At present, the central hot water in the home is a very popular lifestyle in Europe and America. Central hot water supply systems are used in more than 90% of homes in countries with high quality of life such as Australia and Europe and the United States. With the rapid development of China's economy, consumer demand for quality of life is also increasing, and the central thermal system for air energy has also been widely used in China, becoming a popular trend.
The heating function of the central air heater of air energy is automatically activated according to the temperature in the water tank, ensuring that the hot water is supplied in 24 hours. Therefore, there will be no problem like the gas water heater cannot satisfy the multiple taps with hot water at the same time. Water heater capacity is small, many people need to wait for the bath. Immediately after the hot water is used, the amount of water is large and the temperature of the outlet water is stable.
According to experts, the so-called central hot water system uses a central water heater to connect multiple outlets. It can supply showers, washbasins, kitchens and washing machines through pipes to achieve long supply of water for households. It is not only an ideal accessory product for real estate developers, but also more importantly it can provide people with comfort and convenience for living and living. It is an indispensable auxiliary equipment for modern city construction. The air energy water heater has the characteristics of high efficiency and energy saving. Its energy saving effect is 4 times that of the electric water heater, 3 times that of the gas water heater, and about 2 times that of the solar water heater. Calculated by a family of four, the normal hot water usage is about 200L/day. With an electric water heater, electricity costs about RMB 4/day, while the air-powered central water heater only costs about RMB 1/day. Save about 1,000 yuan in electricity bills.
With the increase in the level of national consumption and the increase in consumer demand, the application of the air-energy home central hot water system will form an upsurge, and it is very likely that the type of supply of the water heater market will be around for a longer period in the future.

The jumper wire is actually a metal connection wire connecting the two demand points of the circuit board (PCB). Due to different product designs, the material and thickness of the jumper wire are different. Most jumpers are used for voltage transmission of the same potential, and there are also reference voltages used for protection circuits. For those with precise voltage requirements, the voltage drop generated by a little metal jumper will also have a great impact on product performance.
There are many small square plastic caps on motherboards, hard drives, and the inside of them is metal (this is the jumper cap, which is used to change the circuit, that is, the jumper).There are computer board jumpers, optical fiber jumpers, network jumpers and so on.
