Electric water heaters are typically used in cities that are full of high-rise buildings. If we install the water heater on the roof of the building, it may take a long time for the water to flow down. This is a waste of time and water resources. Larger residents are virtually not allowed to install solar energy devices due to the city's property management. The euphemistic name is for everyone's safety, but it's actually about reducing building maintenance costs. Solar power is relatively energy efficient. Many rural areas use well water. If solar power is installed later and the utilization rate is high, the cost is relatively low, especially compared to electric water heaters. City residents have to pay their water and electricity bills, so efficiency is more important.
The most important point ist that solar water heaters use solar energy to reduce costs, and are energy efficient and environmentally friendly. If electric water heaters are used, the cost is relatively high and natural gas is not. popular in rural areas, and natural gas water heaters are not practical. This is mainly due to the fact that farmers have few financial resources. Once invested in solar energy, they will benefit for a lifetime, because sunlight costs no money and is inexhaustible. Additionally, when electricity consumption is limited, electricity restrictions and power outages in rural areas are more likely. Therefore, from a heating point of view, it is not as convenient as in the city, and more and more people choose solar energy.
City dwellers live in high density, and the cost and cost of installing a meterper household for water, electricity and gas are relatively low. It is suitable for many users and is very common. Nor would I choose to “go against the flow” and lose sight of the other. It is impossible for city dwellers, especially those who live on dozens of floors, to install solar power upstairs. The second reason is that by the time the hot water reaches the bottom, the water is no longer hot and there is not enough water. The third reason is that once the water pressure is insufficient, there is no way to put cold water. Solar water heaters can only be installed on bungalows or rooftops and have relatively high installation environment requirements. Electric water heaters have virtually no installation environment requirements and can be installed anywhere there is water and electricity.
In short, the installation of water heaters and ground energyarea, whether urban or rural, is decided based on ease of use and economic benefits. Depending on how the situation develops, solar energy will disappear from the stage of history. Of course, the photovoltaic panels currently installed can both produce electricity and be practical.
