The floors where solar water heaters are used cannot exceed five floors, but now buildings are getting higher and higher, with the lowest having more than ten floors and the highest dozens of floors. floors. If the solar water heater is installed on the top floor, it will be very inconvenient for users on lower floors to use it. They will have to put in a lot of water before the hot water can come out.
According to this calculation, the solar water heater is installed at the top of more than ten floors. By the time the hot water is released, there will likely be very little water left in the solar water heater. And it’s so unnecessary to have to put so much water before each use.
If the ground is too high, installation will also be a problem, as well as subsequent after-sales service and maintenance, so solar power merchants are not willing to accept such commands. There are also buildingswhose top is not flat and where solar energy cannot be installed. For these reasons, fewer and fewer people are using solar water heaters.
Well, now only families living in small courtyards have the conditions to install solar energy, and they are also willing to install solar water heaters. After all, it is very practical and extremely energy efficient. cold winter, as long as it's really nice to be able to take a hot bath when the sun is shining.
