What's with the instant electric water heater? Is there an insulated water tank, or what principle is used to heat cold water instantly?

Instant electric water heaters, among which we all know that some water heaters burn electricity and some burn steam. We all know that electric water heaters use electric heating, but the most important thing of instant electric water heaters is "instant heating", that is, hot water will come out immediately after the water is turned on, so it is called instant heating. At the same time, the instant water heater is also different from the previous electric water heater, because the previous electric water heater was powered on after the water was boiled, and it took a while to use hot water. However, such a water heater has no hot water for a long time, and it takes a while to stop using it to get hot water. It is precisely because of this kind of water storage water heater that it takes a certain time to wait after the original hot water is used up, so now this kind of water heater with hot water after being electrified is called "instant heating" electric water heater! Instant electric water heater, also known as instant electric water heater/instant electric water heater and direct electric water heater, refers to patented products developed by some manufacturers or some high-tech products imported from abroad in recent years. It not only has many advantages such as instant heating, time and electricity saving, energy saving and environmental protection, but also has more considerable economic benefits than ordinary electric water heaters, and is increasingly favored by the majority of home appliance manufacturers and distributors.

Product advantage

The outstanding advantages of this water heater are: first, there is no need to preheat and wait. Instant electric water heaters generally have higher power. When in use, as long as the tap is turned on for a few seconds, or even the hot water is heated at the speed of 1 s for 3 seconds, hot water with appropriate temperature can be supplied, which is very fast and convenient and meets the needs of modern people's fast-paced life. It is very suitable for users who need to provide hot water immediately or for a long time, such as barbershops, hospitals, schools and so on. The most important thing is to save people's precious time. Second, save energy and electricity. The instant electric water heater does not need to be preheated in advance, so the heat energy is lost when it is not preheated. When it is used, it is turned off, and as much water as it is used. There is no energy consumption of unused remaining hot water heated by the storage water heater, which really saves energy, electricity and water. Generally speaking, instant electric water heaters save electricity by 30%-50% compared with traditional electric water heaters. Therefore, the state classifies such products as energy-saving products. In the case of water and electricity shortage, it is undoubtedly of great practical significance to focus on promoting this product. This is also the key factor for consumers to choose instant electric water heaters. Third, safety and environmental protection. For electric water heater products, people are most worried about safety. In order to fully ensure the safety of consumers, instant electric water heaters are generally designed in this respect, such as adopting non-metallic heaters, water and electricity isolation technology, leakage protection devices, grounding protection and other measures. Some manufacturers' products are also equipped with water control switch, acousto-optic alarm, patented circuit, magnetization and anti-scaling, over-temperature power failure, high-voltage discharge, electronic adjustment, temperature display, stepping power supply and other functions, which can be said to be foolproof in safety. Small size, noble appearance, convenient installation and space saving. Because the instant electric water heater does not need preheating in advance, it does not need bulky liner and insulation layer in design, and most of them are small in size, light in weight, convenient to install and save space and materials. In addition, most of the high-grade products in instant electric water heaters are humanized in design, streamlined in appearance, noble and elegant, and are welcomed by fashion people. Wires and pipes can be installed hidden.

5. Constant water temperature and comfortable use. Storage water heater, because it is pre-heated hot water in advance, needs to release water to adjust the temperature at the beginning of bathing, and the water temperature is either cold or hot. Even if the temperature is adjusted, the water temperature will become cold during use, and it is troublesome to fine-tune it from time to time. And the instant electric water heater, no matter how many people take a bath, as long as the water temperature is adjusted at the beginning, it will always be constant temperature and constant current, and it will be refreshing and comfortable to wash. Six, not easy to scale, long life. The instant electric water heater is a kind of "running water" in which cold water directly passes through the heating element and then is heated, so the scale is not easy to stay. When taking a bath, the temperature of hot water is generally not higher than 45℃, so the internal pipeline of the water heater is not easy to form scale. Moreover, in the heating process of thermoelectric water heaters, the temperature rise of machine heating is not very high, and the damage probability of waterways and heating bodies is correspondingly reduced, so the service life of thermoelectric water heaters is generally longer than that of traditional electric water heaters. 7. You can connect a solar water heater. The heating cost of supplementary heating solar water heaters is low, but due to weather and other factors, the water temperature is often low. Connected to the instant electric water heater, tap water can be reheated, the temperature of used water can be increased, and the utilization rate of water can be improved.
