Which is good, electric water heater or gas water heater?
Bibi lifeGas water heater if the gas quality is good, generally can use more than 6 years; electric water heater due to fouling phenomenon is serious, in good water quality can use for 4 years or so. With the longer use time, the heating efficiency of the electric water heater will be greatly reduced.
Bibi price8 liters of gas water heater in the general price 800 yuan, plus the installation fee generally in more than 1000 yuan, and some even close to 2000 yuan; and the electric water heater is priced at 1000 yuan, plus the cost of installation is generally less than 1500 yuan cheaper than gas water heater. From the cost point of view, at present, natural gas per cubic meter is 1.6 yuan, kwh per kilowatt hour is 0.4 yuan. Because both are used to heat water, so the use of heat to less than 1 cubic meters of natural gas heat is 10 kilowatts, 1 kwh electricity heat is 1 kilowatts, the use of natural gas per kilowatt cost is 0.16 yuan, 0.40 yuan per kilowatt of electricity. Therefore, the cost of the electric water heater is 2.5 times that of the gas water heater.
Compare the temperature of the hot waterThe gas water heater is due to rapid heating, and the temperature adjusting device, as long as the feeling of comfortable temperature before starting to use the tune to the people, after the hot water will keep the temperature. The electric water heater is a volumetric type. After heating a tank of water, when it is in use, the water will be heated out of the cold water at the same time as the temperature is high (usually 80 degrees Celsius), and part of the cold water must be supplied at the same time. In the ejection process, the water temperature is higher, and the water temperature will decrease gradually. Therefore, it is necessary to adjust the proportion of cold and hot water constantly.
Bibi heat yieldGas water heater mainly has 5 liters, 7 liters, 8 liters, 10 liters and other specifications, this figure refers to 1 minutes in the water temperature increased by 25 degrees when the amount of hot water produced. Electric water heaters are generally marked 30~90 liters or larger. This number refers to the water capacity of the electric water heater. Take a 8 litre gas water heater and compare with a 60 liter electric water heater. 8 liters of gas water heater can continuously produce 8 liters of hot water every minute. The water consumption is not limited. The electric water heater needs to be heated for half an hour, and a tank of water can be used. If the tank is used up, it will take about half an hour. In winter, if the bath time is not well controlled, a tank of water has not been used up well, then it will take half an hour to continue to wash.
