Which is better for electric water heaters and gas water heaters? Water heater competition
2023-07-02 19:09:01
The water heater market is now mainly dominated electric water heaters and gas water heaters, electric water heaters can not be one-sided judgment and gas water heater which is good, only a relatively more in line with what you need is more suitable for installation in your home. Today Xiaobian can systematically introduce their respective principles and features, so that you can choose the right water heater according to your own specific situation, let's take a look!
First, the principle and characteristics of electric water heater
1, high heating costs
Although the selling price of electric water heaters has now stabilized, more than a thousand can buy quality products, but because it directly relies on electric heating to heat water, the cost of using electric water heaters is the highest among all kinds of water heaters. Generally speaking, the heating cost of an electric water heater is generally about 30% higher than that of a gas water heater, and 3-4 times that of an air energy water heater, which is a type that is expensive to purchase and expensive.
2. Slow heating but constant temperature
The electric water heater heats the water stored inside the machine and the water temperature is constant. Unless the machine is faulty, there will be almost no sudden washing of the hot water in the bath. However, the electric water heater needs to be turned on for a period of time or the temperature is always turned on, and the water temperature can be heated to the required temperature. When the heated water storage is used, it will take some time to continue using it.
3, easy to use
The principle is simple, the structure is simple, the technology is mature, and the price is affordable. These four points are the reason why most families choose electric water heaters. Moreover, another advantage of directly controlling the water temperature by electricity is that with the development of technology, various control functions such as constant temperature, reservation, remote control, and remote operation are gradually matured, making the electric water heater more flexible and convenient to use.
4, need to clean the water tank regularly
Since the electric heating rod directly heats the water in the water storage tank, scale, rust and the like are continuously generated on the surface thereof, and the bacteria are easily generated by accumulation for a long time. This not only affects the water quality, but also affects the heating efficiency of the heating rod, wastes electrical energy, and even causes damage to the water heater. In addition to regularly cleaning the water tank, Haier electric water heater has developed a new technology "clean water washing", from the beginning of the water to block and filter the dirt in the tap water, the sterilization effect of 99% while removing more than 90% of tap water The residual chlorine keeps the water heater liner from corrosion.
Second, the principle and characteristics of gas water heaters
Compared with electric water heaters, the principle of gas water heaters is more complicated: heat is generated by gas combustion, heat is exchanged to the water flow through the heat exchanger, and the water flow is heated to become hot water.
1, ready to use
Hot water can be produced at the start-up, and no pre-heating is required. Of course, this method also brings about the problem that the water temperature is not constant and a cold water is discharged before the hot water is discharged. The problem that the water temperature is not constant has been said above. Now the technical aspects have been basically solved. When purchasing, pay attention to selecting a gas water heater with a constant temperature function.
2, occupying a small space
Although the internal structure of the gas water heater is more complicated than the electric water heater, it does not require a special water storage tank, and the volume is much smaller than that of the electric water heater. In most cases, it can be installed in the kitchen, which can save a lot of space for the bathroom.
3, must have independent flue and gas pipeline
If the home does not have these two conditions, the gas water heater is not available. In addition, the room using the gas water heater must ensure good ventilation. If this condition is not met, it is not recommended to choose a gas water heater.
In summary, we can see that gas water heaters and electric water heaters have their own advantages in different aspects: electric water heaters are simple, reliable, low price, flexible and convenient to control, but need to be heated in advance and have higher cost in later use, which is more suitable for adequate household space. At the same time, households with less hot water demand are used; gas water heaters are small in size and ready to use and low in cost of use, but there are requirements for gas and flue, installation is complicated, and there are certain water problems in the cold water section. Households with more hot water demand. The two have their own characteristics and different scopes of application. It is impossible to say which one is better than the other. The subject should also analyze the actual situation of his family and choose according to the needs. The best for you is the best.
