Which gas water heater and electric water heater are better
In recent years, electric water heaters have developed rapidly and have become strong competitors of gas water heaters.Many consumers will have such questions before buying water heaters: Is it better to buy gas water heaters or buy an electric water heater? Want to know that the gas water heater is better or buy an electric water heater? Let ’s compare it for everyone! China!
1. Electric water heater
1. Safe and convenient: ★★★ ☆☆
The advantage of the electric water heater is that it can adapt to any weather changes. It does not produce exhaust gas during use. It is relatively hygienic. The disadvantage is that the indoor space is large and easy to settle; because the water inside the bile is neededPeople need to wait for gallbladder internal water to rearmed before they can be used, which is not convenient.Although the vast majority of electric water heaters are installed with leakage protection, electric shock accidents during use still occur from time to time.
2. Economics: ★★ ☆☆☆
At present, the calories generated by 1 degree of power are 1 kilowatt, and the average percentage is almost 0.5 yuan, which means that the use of electric water is 0.5 yuan/kW.Compared with the data of 0.2 yuan/kW of gas water heaters, it is obviously a disadvantage at the economic level.
3. Stability: ★★★ ☆☆
Because the electric water heater is volume, after a box of heating, the water temperature just used is high. The heated water roof is needed to use cold water, and at the same time, it must be used to refer to some cold water.During the top of the top, the water temperature began, and it will gradually decrease as the water temperature will gradually decrease.
4. Energy saving: ★★★ ☆☆
Theoretically, the thermal efficiency limit of the electric water heater can reach 100%, that is, the power energy is completely transformed into heat.But this is the same as the concept of absolute zero degree in physics. We can approach infinitely, but we can never reach.Most companies are currently limited by technical restrictions, and the thermal efficiency utilization rate of electric water heaters appearing on the market is only 70%.
5. Life life: ★★ ☆☆☆
In the process of using ordinary electric water heaters, it is easy to produce scale. It can be used for about 4 years when the water quality is better. HoweverEssence
Second, gas water heater
1. Safe and convenient: ★★★★ ☆
The gas water heater solves the shortcomings of electric water heaters to occupy a large space, easy to settle scale, fast heating, and stable water temperature.As for the poisoning of gas water heater often discussed by the outside world, most of them are due to poor ventilation and exhaust, which causes insufficient combustion of water heater to produce toxic gases such as carbon monoxide.In fact, consumers only need to install the water heater in the kitchen and correctly install the flue (except outdoor and balanced machines) that discharge exhaust gas. Pay attention to ventilation and exhaust, and it is quite safe to use.
2. Economics: ★★★ ☆☆
At present, the natural gas is 2.2 yuan per cubic meter.If it is used for heating water, the heat generated by natural gas of 1 cubic meter is 11 kilowatts, and the cost per kilowatt is 2.2 yuan/11 kW = 0.2 yuan/kW. This data is only 40%of the electricity cost.
3. Stability: ★★★★ ☆
Generally, the gas water heater that uses constant temperature is heated rapidly and there is a device that adjusts the temperature. As long as it is adjusted to the comfortable temperature when it starts, the hot water will keep this temperature in the future.
4. Energy saving: ★★★★ ☆
Consumers who often want to buy water heaters ask. Under the same circumstances, if you want to heat up 200 liters from 10 ° C to 45 ° C, the required heat is about 7,000 kcal.Taking energy -saving water heaters with the national secondary energy efficiency standard (that is, the heat efficiency of not less than 88%) as an example, it takes 0.3 cubic meters of liquefied gas;In 96%), the cost of bathing was reduced by 10%; the use of the most energy -saving condensed water heater at present is reduced by 20%.If the "Jun Nengquan" series of condensed water heaters carefully developed by the energy rate, with the secondary heat exchanger with a patented design, not only makes full use of high -temperature smoke gas waste heat to heat cold water, which not only reduces the emissions of exhaust gas, but also allows the thermal efficiency of the water heater to exceed 103 by 103%, Far higher than the energy efficiency standards stipulated by the state, established the overwhelming energy efficiency advantage of competitors within the scope of the first -level energy efficiency.
5. Life life: ★★★ ☆☆
For gas water heaters such as natural gas such as natural gas, it can generally be used for 8 years.Some foreign -funded burning brands such as Japan have been designed by the service life of more than 10 years.With the guidance of the national energy conservation and emission reduction policy and the advancement of the Western Gas Eastern Project, the gas water heater will be more and more popular.The electric water heater has always been in the bile, the inner biliary is easy to scald, and the possibility of leakage bile is affected.
