Is a hot water heater easy to use? The advantages and disadvantages of instant electric water heater

Mentioned that instant electric water heaters everyone can basically understand the meaning of which, compared to the ordinary electric water heater that is the efficiency of electric water heaters is indeed quite high. If you have an electric water heater in your home, you will find that waiting for hot water will wait for about an hour each time. If you are in urgent need of hot water, you will be very anxious. The instant electric water heaters do not have such concerns, namely, what kind of hot electric water heaters are in the end, and how effective is the hot water. Today we will study together.

What is an instant water heater?

The instant-type electric water heater is a type of water heater that can rapidly heat flowing water through electronic heating elements and can control the water temperature, flow rate, power, etc. through a circuit so that the water temperature can reach a temperature suitable for a human body bathing. Immediately after the heat is turned on, there is no need to wait, usually heating can be started within seconds.

The advantages of instant electric water heater?

First, the size of the machine is very small and it is suitable for the needs of a small area of ​​a Chinese family bathroom.

Second, the heating time is short, that is, heat, time and power saving: heating time from the boot to the outlet temperature of 45 degrees only takes 10-20 seconds; the heating of quantitative hot water, that is, heat only need to consume the traditional electric water heater 30% of the time; instant heat, no waiting, even faster than gas water heater heating time.

Third, you can connect multiple ways: You can connect wash basins, showers, bathtubs, shower rooms, villa type can also connect multiple bathrooms at the same time.

Fourth, environmental protection and energy-saving: instant heat, no need to store hot water in advance to reduce energy waste; computer temperature control set, stable water temperature, minimize the waste of energy; special speed setting function, save energy And time-saving power; that is, heat-type products have been domestic and foreign environmental protection agencies certification.

The disadvantage of instant electric water heater?

First, the power is relatively large and the line requirements are high.

Instant electric water heaters require a power of at least 6 kW in order to ensure that the instant heat can be achieved. The requirements for power lines must also be at least 2.5 mm 2 or more, and some require more than 4 mm 2 . Such power and lines are generally unbearable for the current of an ordinary Chinese home circuit 15A.

Second, high installation requirements. For instant water heaters, the inlet pressure must not be too large during installation. Some require that the meter in the user's home is 20A and the air switch is 32A. Generally, there is an independent line, and some even require a dedicated meter of at least 40A. , In addition to household refrigerators, air conditioners, and other high-power household appliances, at least 80A meters will have to be routed separately. This is also a bottleneck that affects the rapid popularity of instant electric water heaters in China.

In general, traditional water heaters are water storage type, with limited water volume, large volume, and space. But the price is cheap, power is saved, and the requirements for the line are not high. Instant water heaters are small in size and can be used by many people. They do not need to consider the amount of water, but they have high requirements for the installation of the line, and they have a large power and a relatively large relative power consumption.

Summary: After reading the above information about instant electric water heaters, everyone has a certain understanding of the instant-type electric water heaters. If everyone has a large power line at home, they can consider installing an instant-type electric water heater if they are old houses. If the line is difficult to change and the pressure capacity is normal, then it is best to use an ordinary water storage type electric water heater. No matter which type of electric water heater is used, we must decide according to the circumstances of our own home.

t should be noted that the nature Manila Rope will shrink when it is wet with water, so the new rope is usually immersed in water and dried before use, so the shrinkage rate is lower than the shrinkage rate when the rope is never wetted, so you need to consider it when using it. To this point.
