Gas water heater and electric water heater which is good electric water heater PK gas water heater

The water heater has now become an essential part of the bathroom among the family, and plays a significant role in the convenience of life. Not to mention solar water heaters have limitations, on the single comparison of gas water heaters and electric water heaters which is good , perhaps it can be learned from the two types of water heaters in the industry market today, which should be selected in the world. Before buying a water heater, we always compare and analyze the advantages and disadvantages of the two and buy a water heater that is relatively suitable for ourselves. Here, I will sort out the comparative analysis of the two tables of electric water heaters and gas water heaters, let's take a look at gas water heaters and electric water heater which is good now.

Specific hot water production

Gas water heater housing will be marked above the 5L, 7L, 8L, 10L and other figures, this is not how much water it can hold, but refers to the amount of hot water in the water temperature rise of 25 degrees Celsius within 1min.

Electric water heaters are divided into three types: instant heat, quick heat, and water storage. The output of the instant-type electric water heater is controlled by the power, and the 7500w is equivalent to the output of the 5L gas water heater. Speed-type electric water heater is an improved version of the storage-type electric water heater, which can reduce the preheating time to 8-15 minutes. If it is a preheating or hot dual-mode electric water heater in quick-heating, it can output 30L water heater. Increased to 180L, completely enough for about 6 people to continue bathing. Storage water heaters typically have a water capacity of 30 to 90 liters or more. Storage-type electric water heaters require an interval of half an hour to heat a can of water. If they are used up, they still need to wait for half an hour.

Temperature stability

The gas water heater is a rapid heating method that can adjust the temperature through the device, and as long as it is in use, it can maintain this temperature.

Instant electric water heaters can be divided into mechanical and thermostatic type. Mechanical equivalent to gas water heater temperature control, when adjusted to the appropriate location, the future of hot water will also keep this temperature unchanged. The constant temperature electric water heater can accurately select the outlet water temperature, which belongs to the microcomputer intelligent control. A tank of high-temperature hot water stored in a storage-type electric water heater can be adjusted to a suitable temperature by using a mixing valve against cold water at the time of use. When the hot water is used up, the water becomes colder and colder. According to the inconvenience of water storage, quick-heating electric water heaters have improved the heating technology and use the preheating and heat double mode. When the hot water is not hot enough, the heat function is automatically activated, which can ensure a constant temperature of the outlet water.

Specific safety

Gas water heaters use liquefied petroleum gas or natural gas, and a few use artificial gas. These substances generate toxic waste gas during the combustion process, and can easily lead to poisoning and death if the discharge measures are not smooth. This is very dangerous. There is the need to burn oxygen consumption, if the bathroom is more sealed, it is prone to lack of oxygen, resulting in dizziness and suffocation. For example, two types of gas-fired water heaters, ie, the forced-bunker type and the flue-type gas boiler, use indoor oxygen combustion, resulting in relatively large safety risks. Balanced gas water heaters do not use indoor oxygen, as long as the flue is not damaged, the normal operation of the water heater is still safe. Electric water heaters mainly need to solve the problem of leakage. At present, every electric water heater is equipped with a leakage protection switch to completely prevent electric leakage and cause accidents. If the advanced high-end electric water heater has more detailed protective measures, such as sealing the main board waterproof plastic, waterproof keys, etc., can be more stringent than the waterproof mobile phone.

Than cost performance

The price of an 8-litre gas-fired heater starts at about 1,000 yuan. If you add installation and other costs, it should be more than 1,500 yuan, or even nearly 2,000 yuan. An electric water heater is sold at a price of more than a thousand yuan, but the installation cost is not expensive for a gas water heater, which is relatively cheaper.

From the perspective of energy consumption, gas water heaters consume liquefied petroleum gas and natural gas, and these two prices continue to rise, so prices are rising. A family of 3, the cost of using liquefied gas for one month is about 100 yuan. And then compare the electric water heater, the current price drop, about 0.6 yuan once, according to one-hour bath a day calculation, about 60 yuan a month.

Electric water heater and gas water heater PK summary

From the perspective of ease of use and comfort. Gas water heater water temperature is stable, heating speed, and electric water heaters need to wait for a while, bathing too long, the electric water heater because it is volumetric water, the tank temperature will gradually decline, a long bath time friends have to seize the time.

From the perspective of environmental protection and installation and maintenance costs. Gas water heaters have higher energy consumption. With the increasing price of gas, the cost of using gas water heaters is relatively high, and electric water heaters can heat and store hot water at the time of valley power, and the cost of energy consumption is relatively low, especially the price of electricity is relatively low. In rural areas, electric water heaters will cost a lot.

From a security point of view. Gas water heaters need to be installed in an open space. Doors and windows need to be opened when they are used. If the room is not ventilated, gas and water vapor can easily generate colorless and odorless carbon monoxide, which can easily lead to carbon monoxide poisoning. Electric water heaters are prone to electric leakage accidents, especially for instant electric water heaters. For a storage electric water heater, it is best to turn off the power while bathing. However, electric water heaters now have leak-proof systems, and their safety performance is relatively higher than before.

Editor's summary: The above is the gas water heater and electric water heater which is good electric water heater PK gas water heater related introduction, hoping to help meet the needs of friends!
