(2) Scale and scale-free service life is as long as 30 years.
(3) Intelligent water control system. Intelligent functions such as automatic water supply, automatic heating, leakage protection, voltage loss protection, overcurrent protection, etc., without supervision, reasonably save electricity.
(4) The patented technology of safety and normal pressure makes the water tank pressureless and explosion-proof safer. A special box lock is set to prevent illegal elements from poisoning the water heater. The boiled water is filtered by three stages (PPK+KDF+ double high-efficiency activated carbon) and sterilized at high temperature.
(5) Beautiful all-stainless steel manufacturing, water tank molding and ergonomic design.
Uses: schools, kindergartens, hospitals, factories, etc. 1. heating mode: it is divided into three boxes: cold water tank, boiling water tank and water storage tank. The cold water tank and the water storage tank for supplying boiling water are not communicated with each other. Only when the water in the kettle reaches 100 degrees, a large amount of steam will spray boiling water into the water hose in the water storage tank before it can come out, thus completely eliminating the yin and yang water and completely separating the raw and cooked water.
2. It takes about 5-6 minutes to boil for the first time, and then the water is continuously supplied.
3. High-power heating (in the boiling water tank) and low-power heat preservation (in the water storage tank, the heat preservation temperature is about 90 degrees) adopt high-power and low-power double heating pipes, and the two pipes will not work at the same time, which not only ensures the heating speed, but also saves electricity during heat preservation.
The water inlet of this boiler is on the side of the boiler, and there is an exhaust valve on the back to let excess steam overflow.
Strictly speaking, the boiling water boiler is the most mainstream model for supplying pure 100 degree boiling water on the market, and most universities and hospitals in China are using this model.
6. Disadvantages: Because the water temperature is higher than that of ordinary water heaters, the maintenance requirements in areas with more scale are higher, and it is necessary to clean the scale in time, otherwise it will easily lead to failure. 1. heating mode: heating step by step, heating and water inflow are controlled by temperature probe, and high and low water levels are controlled by water level probe.
2. Adopt step-by-step layered heating technology. After taking water, you can feed water layer by layer, heat it layer by layer, and continuously provide boiling water above 90 degrees. Heating layer by layer.
3. The first boiling time is 15 minutes. After the first boiling, you can take it with you without interruption or waiting.
4. Microcomputer control: automatic detection function of water cut-off, overflow, abnormal water inflow and fault.
5. Disadvantages: The water can only reach 99 degrees at most, and it can't really boil. Moreover, due to the single box structure, yin and yang water are generated when cold water is injected, which cannot completely kill all the delicate and instantaneous opening.
There are many versions about instant opening. The timely electric heating film has poor applicability and is gradually improved, but it still has heat preservation, which is not a real instant opening type. Let's just take the Novo instant electric water heater as an example. Open at once, that is, using the principle of water flow heating. Cold water is heated while walking in the water flow cavity, and the temperature rises in turn. After reaching the end point, boiling water overflows. Circulate in turn to form a steady stream of fresh boiled water. After the faucet is turned off, the water level signal at the end indicates to stop water inflow, and the heating will stop. There is no residue of boiling water in the whole process, and the part without boiling cannot flow out. Burn as much as you want, always use fresh boiled water.
Advantages:
1, the whole machine no longer needs heat preservation, so it doesn't take time to turn on and off the faucet when the energy is turned off;
2. Fundamentally solve the problems of boiled water, yin and yang water, aged water and overnight water;
3, access to boiling water is fast, and the longest waiting time is tens of seconds;
4. Use the steam and electric energy generated in the working process to preheat the cold water in the process, so that the steam does not leak out. In addition, it doesn't need heat preservation, and it doesn't need to consume energy for a day without water supply, so it has high energy saving rate and is superior to various water tank boilers;
5, highly intelligent integration, the whole machine is controlled by single chip microcomputer, and the electric heating system is contactless, so it is safer to apply digital water level detection technology;
6. Compared with the water tank electric water heater, it is compact and fashionable.
