Advantages: solar water heaters have no noise, no pollution, no poisoning and other dangers, are reliable in installation, low carbon and environmentally friendly. 'environment ; solar energy itself has high-tech processing technology and good heat transfer. performance, large hot water production and suitable for use by several people in the family; In cold winter, solar water heaters have strong frost resistance. In summer, large-area solar water heaters can also insulate floors.
Disadvantages: The solar water heater is large in size, inconvenient to install, and has certain 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 depends relativeresources if areas with cloudier and rainier days are not suitable for solar energy.
Detailed information
Theoretically, solar water heaters are a one-time investment and cost 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 many cloudy days). Actual electricity consumption in the region is even higher.
Statistical data in the Shanghai area in the past three years show that the annual average of rainy days reaches 67%, and 70% of theThe 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, solar water heaters also have many structural technical defects that are difficult to resolve.
The solar water heater lighting panel needs to be installed on the roof, which is large and cumbersome, affects the beauty of the building (more obvious in high-end residential areas), and can easily damage the waterproof layer of the roof.

What is thebetter, an electric water heater or solar energy? Take 5 minutes to fully understand
1. Install a ball valve on the solar hot water outlet pipe When using solar energy, the valve opens and the electric water heater valves are closed. at the same time. In this way, solar water can be used. When using an electric water heater, close the solar valve and open the electric water heater valve.
2. The solar water heater tank is equipped with auxiliary electric heating. If the water temperature is not sufficient, you can directly use auxiliary electricity to heat the water temperature, which is much faster than the heating time. of an electric water storage water heater. When the weather is bad, do not fill the solar water tank, just fill it halfway. In this way, the heating time will befaster, which will make it easier to use hot water.
If you want to connect a solar water heater and an electric storage water heater, you need to buy two tees and a water valve to connect the connecting water pipe of the solar water heater to the water pipe of the electric water heater.
3. Electric water heater refers to a water heater that uses electricity as energy for heating. It is one of the three main water heaters, alongside gas water heaters and solar water heaters. Electric water heaters can be divided into three types according to heating power: water storage type (also called volumetric type or heat storage type), instant heating type and instant heating type.
4. Solar water heater is a device that uses sunlight to heat water. Solar water heaters are divided into vacuum tube solar water heaters and heatingflat panel solar water heaters accounting for 95% of the domestic market share. Household vacuum tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into thermal energy mainly relies on vacuum heat collector tubes. Pouring cold water to produce microcirculation in the water to reach the required hot water level.
Which is more convenient, water heaters or solar energy?
If you want to move into a new house, you need to First purchase and install electrical appliances, such as TVs, refrigerators, air conditioners, range hoods, water heaters, etc. , otherwise it will be a lot of trouble after recording. Today, the editorial team asks you a question: is it better to install an electric water heater or a solar water heater in a house?new ison? The following is an analysis made by the editor for everyone. If you think the article is very practical, you can forward it to your relatives and friends. Good things should be shared together. 1. Electric water heater The editor will first give you an analysis from the point of view of the electric water heater: The electric water heater is relatively large. If the bathroom is already small, it will become very cluttered if the electric water heater is installed. Additionally, the water heater's water tank has limited water storage. If several people are bathing in a row, it may take some time for the water to heat up before cleaning. 1) Convenience: It takes time to heat up and the volume is low. The bath must be staggered, otherwise you have to wait. 2) Safety: Today's electric water heaters come with necessary safety measures, but you still need to be careful when using them to avoid accidents.leaks. And when using, the power plug should be plugged in well, and it is better to unplug it when not in use. 3) Energy Saving: As the name suggests, electric water heaters use electricity to produce hot water. They are relatively expensive and can cost a lot of electricity all year round. 2. Solar Water Heater Let me analyze it from the point of view of solar water heater: although solar water heater is expensive, it does not require electricity or gas for its use, it only needs of a balcony, these costs can therefore be omitted. In addition, current solar energy can provide hot water even in cloudy and rainy days. Thanks to its electric heating function, you are not afraid of cold water. 1) Convenience: Usually placed on the roof, it does not take up space at home, and as long as there is sunshine, hot water will come out, no need to wait, which is verypractical. 2) Safety: There is no need to worry about leakage from solar water heaters, it is very safe. 3) Energy saving: Although the price of solar water heaters is high, you don't need to pay electricity and gas bills when you use them, so overall it is very energy efficient. In summary, the editor believes that solar water heaters have more advantages than I recommend. If you are torn between the two, you can choose solar energy. But if the current budget is tight, you can also choose an electric water heater, but you should pay special attention to safety when using it to avoid causing serious accidents.
Solar energy is convenient.
Although solar water heaters are expensive, they do not require electricity or gas to use. They only require a balcony, so these costs can be omitted. In addition, the energyCurrent solar can provide hot water even in cloudy and rainy days. Thanks to its electric heating function, you are not afraid of cold water.
Convenience: Usually placed on the roof, it does not take up space at home, and as long as there is sunshine, hot water will come out, no need to wait, very convenient .
Safety: There is no need to worry about leakage from solar water heaters, it is very safe.
Energy saving: Although the price of solar water heaters is high, you don't need to pay electricity and gas bills when you use them, so overall , they are very energy efficient.
Most solar energy uses sunlight for heating, which is very dangerous. Electric water heaters are more dangerous. You must unplug the power when taking a shower. Additionally, you need to install anti-electricity walls and the like. pro functionsprotection. Electric water heaters are more dangerous. The maximum lifespan is 8 years. If not properly maintained, they will age easily and pose a great safety hazard.
Solar water heaters do not require the addition of gas or electricity, are energy efficient, environmentally friendly and are safer to use. However, modern solar water heaters all have electric auxiliary heating. Solar heating is the essential part and electric heating complements it. In short, you can take a hot bath all year round.
