The design of bathroom equipment is divided into solar water heaters and electric water heaters. So, Which is better, solar water heaters or water heaters? This is a question that many owners ask themselves. In fact, both have their own advantages and disadvantages. When purchasing, you should choose according to your own needs. Next, let's see with the editor which one is better between solar energy and water heaters, and what to pay attention to when buying. and using solar water heaters.
1. Which is better, solar energy or water heater?
1. In terms of energy saving. From this point of view, it seems that the former is more suitable, since it consumes too much energy and does not require electricity bills. However, in case of continuous rainy days, electric supplementary heating is necessary and the electricity bill will increase accordingly. a lot, thenthat the latter power Generally between 1000 and 2000W, it consumes a lot of energy. However, it is more inconvenient to use solar energy in winter because the temperature cannot be reached, so hot water cannot be used.
2. Security. Relatively speaking, the former is safer. Since the water is heated by the sun, there is no danger. The second uses electricity to heat water directly, which can be relatively dangerous. However, whatever style you choose, quality must be assured. pass the standard to ensure the health of all.
3. Installation angle. As we all know, the first one must be placed high and cannot be covered with shadows, otherwise the heat will not meet the demand and the water will not heat up, so the installation is more difficult, while the second is easier. to install and can be installed anywhere. There are no restrictions, so the dThey have their own advantages and users can choose according to their own circumstances.
2. Which is better, solar energy or water heater? Points to note when purchasing solar water heaters
1 Nowadays, many solar water heaters are equipped with electric heating and inferior quality. The electric heater is made of ordinary stainless steel. If you work for a long time in a high temperature and high humidity environment, it will rust and wear out over time. The heating wire will leak and soak in the water, causing the water to leak. be charged with electricity and injure people. The right electric heater uses Ingle 800, which is a high chromium and nickel stainless steel used in the oil drilling industry. The corrosion-resistant nickel-chromium content reaches 55%. It was tested in a 5% salt spray box. hungnt 48 hours and there are no signs of rust. Of course, the costs of these two types of electric heating are certainly different.
2. The vacuum degree of ordinary vacuum is 10-2pa, the vacuum degree of a good vacuum tube is up to 100 times, and the cost of suction is more than 10 times that of a surface lower; The anti-freeze belts are dented, and the surface of the poor-quality anti-freeze belts is embedded anti-freeze tape, and the joints are heat shrunk and sealed. The thickness is generous and the surface is smooth and wrinkled. free.
3. Inferior copper accessories have poor copper quality, blisters and thin walls. Copper accessories have many threads, deep threads and are heavy. son. It's deep and has a thick outer wall, but when you take it and weigh it, it's obvious there's a lot of difference.
3. Which is the bestr between solar energy and water heater? Precautions for using solar water heater
1. Don't unplug the plug frequently, just follow the steps above and test. the leakage protection cap at the same time. When you press the test button, the power will be cut off immediately and the red light will go out. Otherwise, the leak protection cap must be replaced or repaired.
2. The water tank ventilation hole must be clear.
3. It is strictly forbidden to expose vacuum tubes to the sun with empty tubes.
4. When the water level in the vacuum tube is insufficient under the sun, it is strictly prohibited to inject cold water into the water tank abruptly.
5. The electric heater must have a leak-proof cap and be turned off.
Solar water heaters have a high usage rate in daily life, propTherefore, owners should purchase branded water heaters when purchasing. It is not only convenient to use, but also has a longer service life. providing for the needs of all Which is better, solar energy or water heating?
Advantages: solar water heaters have no noise, no pollution, no dangers such as poisoning, reliable installation, low carbon and environmental protection. the environment ; solar energy itself has high-tech processing technology, good heat transfer. performance, large hot water production and meets the requirements of It can be used by several people in the family; In the cold winter, solar water heaters have strong frost resistance, and in summer, large-area solar water heaters can also insulate floors. .
Disadvantages: the solar water heater is large in size, impractical to install and has certainne restrictions on installation conditions due to its large size and complex objects, maintenance is more tedious and needs to be repaired by professionals; Solar energy has a negative impact on sunlight. It is relatively resource dependent so areas with cloudier and rainier days are not suitable for solar energy.
Detailed information
Theoretically, a solar water heater is a one-time investment and costs nothing to use. It's actually impossible.
The reason is that no matter where you are, the weather is cloudy, rainy and snowy and there is insufficient sunshine in winter every year. In this climate, hot water is mainly heated with electricity (some products are heated with gas). On average, more than 25-50% of hot water must be heated entirely with electricity each year (this varies by region). , and there are manycloudy days). Actual electricity consumption in the region is even higher.
Statistical data in the Shanghai area in the past three years shows that the annual average rainy day reaches 67%, and 70% of the thermal energy of solar water heaters comes from electricity or gas).
As a result, the actual power consumption of solar water heaters is higher than that of heat pump water heaters. In addition, the “anti-freeze belt for electric heating (only available in northern regions)” installed on the external pipeline of the solar water heater also consumes a lot of electricity. In addition, there are many technical defects in the structure of solar water heaters that are difficult to solve.
The solar water heater lighting panel should be installed on the roof, which is large and bulky, affects the beauty of the building (more obvious in residential areashigh-end) and can easily damage the waterproof layer of the roof.
