Electric water heater and gas water heater distinguish the most electric water heater

In the end, which gas and electric water heaters are good? This makes many users and friends very entangled, combined with their own actual situation, in terms of personal preferences, in fact, gas and electric water heaters have their own advantages and disadvantages, how to choose, today Xiaobian brings the difference between the electric water heater and the gas water heater and the latest quotation of the electric water heater. Let's take a look.

The difference between electric water heater and gas water heater

1. Hot water production

Gas water heaters mainly have specifications of 5 liters, 7 liters, 8 liters, 10 liters, etc. This figure refers to the amount of hot water produced when the water temperature is raised by 25 ° C in 1 minute. Electric water heaters are generally marked with 30 to 90 liters or more. This figure refers to the water capacity of an electric water heater. Taking an 8-liter gas water heater compared to a 60-liter electric water heater, an 8-liter gas water heater can continuously produce 8 liters of hot water per minute. There is no limit to the amount of water used. The electric water heater needs to heat a can of water for half an hour. If the water is used up, it will take about half an hour. In the winter, if the bath time is not well mastered, if one tank of water is used up and not washed, then it will take half an hour to continue washing.

2, the stability of the specific temperature of hot water

Since the gas water heater is rapidly heated and has a temperature-adjusting device, as long as it is adjusted to a comfortable temperature at the beginning of use, the hot water will maintain this temperature for a while. The electric water heater is of a volumetric type. After heating a tank of water, the temperature of the water heater is high (usually about 80 °C), and the heated water is topped out with cold water, and a part of the cold water is exchanged. In the process of ejector, the water temperature starts to be higher, and the temperature gradually decreases as the water temperature is used. Therefore, it is necessary to constantly adjust the ratio of cold and hot water during use.

3, thermal power

The power of gas water heaters is much larger than that of electric water heaters. Compared with an 8-liter gas water heater and a 60-liter electric water heater, a 60-liter electric water heater generally does not exceed 3 kW, while an 8-liter gas water heater has a power of 16 to 17 kW, which is equivalent to 5 to 6 times that of an electric water heater. . Can electric water heaters be made of 16 kilowatts? No, summer is the use period of air conditioners, electricity is tight, and electric water heaters with a power of 16 kilowatts are used. Electricity meters and wires are overwhelmed.

4, the price

The price of 8 liter gas water heaters is generally above 800 yuan, plus the installation fee is generally more than 1,000 yuan, and some even close to 2,000 yuan; and the price of electric water heaters is more than 1,000 yuan, plus the installation cost is generally less than 1,500 yuan. It is cheaper than gas water heaters.

From the point of view of the use cost, the current natural gas is 1.6 yuan per cubic meter, and the electricity per kilowatt hour is 0.4 yuan. Since both are used to heat water, the heat is 1 kW of natural gas, 10 kW, 1 kWh of electricity is 1 kW, and natural gas per kW is 0.16 yuan. Kilowatts is 0.40 yuan. Therefore, the cost of using an electric water heater is 2.5 times that of a gas water heater.

5, the stability of hot water temperature

Since the gas water heater is rapidly heated and has a temperature-adjusting device, as long as it is adjusted to a comfortable temperature at the beginning of use, the hot water will maintain this temperature for a while. The electric water heater is of a volumetric type. After heating a tank of water, the temperature of the water heater is high (usually about 80 °C), and the heated water is topped out with cold water, and a part of the cold water is exchanged. In the process of ejector, the water temperature starts to be higher, and the temperature gradually decreases as the water temperature is used. Therefore, it is necessary to constantly adjust the ratio of cold and hot water during use.

6, security

Since the gas water heater uses a large amount of exhaust gas when it is used, carbon dioxide is present in the exhaust gas in addition to carbon dioxide. Under normal use and good ventilation, carbon monoxide is very small, but if the doors and windows are closed when used, the ventilation will be poor, carbon monoxide will increase, and poisoning accidents will occur in severe cases. Gas water heaters are very safe if you pay more attention when using them.

The electric water heater does not generate exhaust gas when it is used. From this point of view, it is safe and sanitary, but it should also pay attention to the electric water heater leakage problem. Although electric water heaters are equipped with leakage protection, electric shock accidents caused by the use of electric water heaters also occur from time to time.
