What are the specific advantages and disadvantages of solar water heaters compared to electric water heaters?
Not everyone can live without a water heater. Maybe it's warmer now. No one else likes to use hot water, but even in the south I have to start taking showers in October. After getting off work, I take a hot bath, how comfortable it is to come home, but if the water heater at home does not give power, the water temperature is too late, it that is to say embarrassing.
So, the editorial team invites you to discuss the choice of water heater, and if we chose solar water heater or water heater?
Is there a solar or electric water heater in the house? While my household electricity bill was expected, it wasn’t so great!
Excellent solar water heater
Solar water heater
Advantages: safety, environmental protection, ecoenergy saving. Particularly, there is a solar energy rotation system with auxiliary electric heating function, which is mainly solar energy and the electric energy is auxiliary, so that the solar energy can be used normally during a year.
Disadvantages: Installation is more complicated. Once installed incorrectly, it will affect the appearance and quality of the house, and repairs are more difficult. And solar power is usually installed on the roof, which makes cleaning it outside more difficult. Generally speaking, high-rise buildings cannot use solar energy, and for low-rise residential buildings, 1-3 wires will be relatively large.
The current use of solar energy has not been thought through in depth, no solar energy exceeds 20%, some are more, this is how to solve it.
In addition, the energysolar energy has water pressure problems. If the water pressure in the water tank is lower than the solar power, it will be powered without water and the booster pump will need to be solved.
Water heaters
Advantages and disadvantages of electric water heaters
There are three main types:
1 Electric water heater storage: you can use it for a long time Store hot water, the temperature is generally kept above 60 degrees, but temporary water is waiting, the stored water is limited, usually just take a bath, the larger the capacity, the more water is stored.
Gas electric water heaters: have fewer safety and odor issues. But the water is fast and it doesn't wait.
This is a thermoelectric water heater: cold water will immediately rise to the water heater, often called water. The water is fast. The water heater is bulky and consumes a lotoops of energy. Associated electrical equipment should be complete and used with caution in older residential buildings. There is no limit on hot water. How much does it cost ? In addition, the water heater does not retain a large amount of water and can be placed in the bathroom cabinet.
Advantages: It’s practical and quick. As long as there is electric water, there is hot water and the wires for installing the water heater are hidden. Users can install it regardless. high or low level.
Disadvantages: Large size, less space in the bathroom, easier to use, very expensive. At present, electric water heaters are generally equipped with magnesium rods to remove dirt, but to solve the problem of dirt, this magnesium needs to be replaced every two years, and it is more troublesome. Water heater coatings have a relatively short lifespan and should be replaced without delay.s regularity. It is recommended to choose electric water heaters with a round shape better, because round water heaters are uniform and better withstand high pressure.
Comprehensive comparison of solar and electric water heaters:
Usually, the price of solar energy is around 2,500-3,000 yuan, while the water capacity is between 140 ml and 170 ml, but the price of electric water heaters between 300 and 3000.
Solar energy relies on sunlight for hot water, and there is no will not have dangerous accidents; Electric water heaters are powdery, so there will be certain safety risks.
Solar life generally lasts between 10 and 15 years. It can be used for a long time in the installation; although the electric water heater is installed, each period of cleaning and maintenance is very tedious.
Electric water heaters use electricity to heat energy, and thes usage costs are mainly electricity and water costs; in the future, when you use solar energy, you will only need water charges and no electricity charges; However, if there are children and elderly people at home, it can also be charged with solar energy. After all, it is more comprehensive to meet the needs of all family members.
Comparison between solar water heaters and other water heaters: cost-performance ratio
The selling price of solar water heaters is between 4 500 and 6500, which is slightly higher than that of electric water. Water heaters and gas water heaters, and higher than air water heaters, are slightly lower and belong to the average price range. Solar water heaters have a low cost of ownership and offer one-time investment and long-term benefits. Under normal circumstances, use themThey can recoup their investment within 3 to 4 days when they use solar water heaters.
Comparison 2 between solar water heaters and other water heaters: safety
As a green and clean renewable energy, solar energy does not emit gases toxic waste like gas water heaters during the heating process. . Pollute the environment and endanger the lives of users. However, users should pay attention to the installation of solar water heaters and should connect reliable ground wires to avoid the risk of leakage and electric shock when using an electric space heater. In summer, the hot water from the solar water heater can reach boiling point, so be careful to avoid burns when using it.
Comparison 3 between solar water heaters and other water heaters: wide range of applications
Unlike gas water heaters and heatersElectric water heaters that have a single function, solar water heaters can also be used in conjunction with other energy sources, such as solar floor heating, solar panels, etc., allows 24 hours uninterrupted operation out of 24 to meet the different living needs of the family.
Comparison 4 between solar water heaters and other water heaters: longer lifespan
The lifespan of gas water heaters on the market is 8 years, and that of electric water heaters is 10 years. If used properly, the lifespan of solar water heaters can reach more than 15 years, which is comparable to the lifespan of air-to-energy water heaters.
Compared with other water heaters, solar water heaters have obvious advantages, but they also have certain disadvantages. Solar water heaters rely heavily on sunlight. In summer, solar water heaters can faIt can easily produce a large amount of hot water at high temperatures, but this is when users' demand for hot water is lowest. In winter, rainy weather is common. and the ambient temperature is low, so the heating efficiency of solar water heaters decreases. There is not even hot water production. In order to meet domestic hot water needs, the additional electric heating function must be activated, which provides a reduction. a lot of inconvenience for users and considerably increases the cost of use. Consumers want to enjoy a more comfortable hot water life regardless of season and weather. Affected by air, an air-energy water heater capable of providing constant temperature hot water 24 hours out of 24 would be a better choice.
