There are three types of electric water heaters: hot type (that is, hot when turned on, without waiting, and bathing is not limited by the number of people), fast type (you can take a bath after waiting for 5- 10 minutes, and take a bath while heating), and water storage type (generally waiting for 15 minutes in summer, at least 30 minutes in winter, the greater the number of liters, etc.). However, generally speaking, the requirement of the instant heating type is relatively high, at least 2.5 or 4 square lines, that is, your home decoration can be equipped with air conditioning, and the air conditioning line is generally 4 square lines. I saw Knox's instant water heater in the shopping mall, which is the latest thermostat and can be installed on line 2.5. I heard that buying a machine is equivalent to three sets, that is, there are three kinds of power that can be adjusted according to your line. Generally, bathing in winter 10 minutes costs 7-8 cents, and it costs 3 cents in summer. Compared with the 40-liter storage type, there are three people in your family, and the third person usually has to wait.

40 liters, usually two! If your family buys 50 liters, it's just right. If you are alone at home today, burning 50 liters of water is a waste of electricity and water. Because you are alone at home, you can only use 20 liters of hot water at most! ! If two friends come to your house today, then 50 liters is only enough for three people, and those two friends will have to wait! If the first two people in your family take a shower first and it takes a long time, then use more hot water. Then, when you take the last bath, cold water may come out in the middle! When taking a bath with stored water, it is not heated at the same time! ! Moreover, the water storage type is relatively large in volume, occupies a large space and has limited installation conditions. It is forbidden to hang the water storage type above 100 liter on the wall, which will have an impact on the wall. The important thing is that the houses are all high and hollow bricks, and the stress is limited! ! ! If you leave it on all day, you need electricity to keep warm. Go out to travel, the water in the water storage tank will stink, and you will be busy when you come back from travel! ! ! Even the thermal model is small in size, does not occupy space, and is also beautiful. When installing, it is required to pull a special line, which is safer to use and will not affect the electricity consumption at home! ! How much water to wash, how much water to use, how much water to burn, there is no waste at all! ! There are three brands whose time is professional and instant style: Spa Achuang, Blue Medal and Knox. There are also famous enterprises in Delux, all of which use copper heating systems. The heating system includes heating wire and cup body, and only the cup body made of copper is not easy to be damaged when it is hot or cold (that is, it is hot when it is opened and hot when it is cold), because copper has good ductility. The important thing is that the cups of these enterprises are all integrally formed, and there are no welding points! Safety can be assured, there are electricity-proof walls and top ten safety guarantees! Therefore, if you choose, you can choose a company that specializes in water heaters. Companies with a long history, namely Autran and Harvard, have the best sales in China, but Autran uses stainless steel heaters, Harvard is non-metallic, and Jiayuan uses enamel liners. After reading their color pages, they said that the heating wire is copper, but looking at the internal structure inside, compared with imported brands, it really feels a bit like that! ! As the saying goes, a white horse is not necessarily a prince, and the best-selling materials are not necessarily the best! ! Watching the news is about the instant energy efficiency labeling management system, which was initiated by NOKS (an imported brand from Australia). And when I went to the store, I saw that it was labeled, and it was certified by the national testing department with a certificate. ......................................................................................................
