The Importance of Solar Water Heaters

First, using a solar water heater consumes no conventional energy, but rather inexhaustible solar energy. The sun constantly generates 3.9 x 10⊃2;⊃3; kW of energy during the fusion reaction. The Earth's surface can receive approximately 8.5 x 10⊃1;⊃3; kW of power, equivalent to tens of times the world's electricity generation. The solar energy stored in hydrogen reactors is enough to sustain life for 60 million years.

Second, solar water heaters are safe and reliable. There is no risk of explosion, leaks, or seepage, and they also eliminate the risk of personal injury. They operate automatically, are simple to use, and require almost no maintenance. Furthermore, solar water heaters do not release solids, liquids, or gases, and therefore have no negative impact on the environment. If the auxiliary heating of the solar water heater can fully operate, even at night or on rainy days, and when the sun is hidden by clouds, it can be used in all kinds of weather.

Currently, the promotion of solar water heaters has expanded very rapidly. In 1997, the sales area reached nearly 300 million square meters, ranking first in the world. Domestically, more than 1,000 companies are involved in the development, production, sales, and installation of solar water heaters, with an annual production value of 2 million yuan.
