With the improvement of people's living standards, many people now choose to buy a water heater when they are renovating. At present, most of the market is still more than gas water heaters than electric water heaters . So what is better? Gas water heaters are different from electric water heaters. It is currently the two types of water heater products that urban residents mainly purchase. What are the differences in the performance of these two types of products? Next, let Xiaobian come to share with you.
First, shortcomings
1. Let me talk about the electric water storage type. The advantage is that when it is used repeatedly in the short term, such as washing your face in the morning, one person should switch the faucet several times. At this time, the electric water storage type can provide continuous and stable hot water. No.
2. The disadvantage is that the water heater has just turned on, and it may take a while to use hot water when it starts to use water. Therefore, it is best to open the water heater in advance when hot water is needed.
3. Besides, the gas fast-heating water heater has the advantages of fast heating speed, hot water can be used in a few seconds after opening, and it can be used now, and does not require a long wait.
4. The disadvantage is that, when used frequently for a short time, each time the water tap is turned on, the water heater must be re-ignited once, and a small amount of cold water will be generated in the middle. Although the time is short, each time we use water, it may take a few seconds. . Another point is that the gas type is generally louder.
Second, the gas water heater is more than the electric water heater
1. General gas water heaters have 5 liters, 7 liters, 8 liters, etc., which refers to the amount of hot water produced when the water temperature is raised by 25 ° C in one minute. If the temperature of the tap water is 25 ° C, it can be produced every minute. Hot water at 50 ° C 5 liters, 7 liters or 8 liters. The electric water heater is generally marked with 30 to 90 liters, and this number refers to the water capacity of the electric water heater, which is equivalent to adding a kettle to the electric stove. The water volume of the kettle is 30 to 60 liters, and an 8 liter is taken. Gas water heaters Compared with a 40-liter electric water heater, an 8-liter gas water heater can continuously produce 8 liters of hot water per minute, while an electric water heater needs to heat one tank of water at intervals of half an hour. If the tank is used up, wait for about half an hour.
2. When bathing in the winter, if the bath time is not well mastered, if a can of water is used up and there is no shower, then it will take about half an hour in the bathroom.
Third, the gas water heater is more stable than the electric water heater from the temperature of the hot water
1. Since the gas water heater is heated quickly and has a temperature adjustment device, as long as it is used to adjust to a person's comfortable temperature (generally 40 to 50 ° C, depending on the person), the constant temperature supply will be maintained. Hot water.
2. Since the electric water heater is of a volumetric type, after heating a tank of water, when used, the temperature is high (generally about 80 ° C). The heated water is to be withdrawn by cold water, and at the same time, a part of the cold water is exchanged. In the process of ejector, the water temperature starts to be high. With the use, the water temperature in the tank gradually decreases until all of it is cold water, so when using it, it is necessary to constantly adjust the ratio of cold and hot water.
Fourth, gas water heaters than electric water heaters from the perspective of thermal power
1. Gas water heaters are many times larger than electric water heaters. Take an 8-liter gas water heater and a 40-liter electric water heater. The power of an 8-liter gas water heater is equivalent to 16 to 17 kilowatts, while a 40-liter electric water heater is generally used. It is about 3KW, which is why gas water heaters can supply hot water continuously.
2. So whether the electric water heater can also be made into 16KW, it is impossible, because the household electric meters and wires can not bear. That is 3KW. If the air conditioner is used during the summer, the electricity is tight, and then the electric water heater is used. The consequences can be imagined.
These are all Xiaobian for everyone, each has their own advantages and disadvantages, but they are all small problems, which may cause a little inconvenience in life, and basically can be overcome. Therefore, there is no need to be particularly entangled when purchasing, the price is right, and the quality is excellent. Of course, there are other aspects, such as saving money with gas, and energy-saving. In fact, these are not big problems. If you want to know other decoration information, please continue to pay attention to the decoration home network.
