What is the solar water heater?
solar water heater is a device that uses the energy of the sun to heat water, which is generally for the domestic or building. This type of alternative renewable energy is one of the most common uses for solar energy. Depending on the type of water heater, there are several different ways to work. In general, all solar water heaters do three basic things: energy collection, energy transfer and energy storage.
Collectors begin with the heating water process in the solar water heater by capturing the energy from the sun. Three basic types of collectors can be used: dose collectors, collectors of flat plates or evacuated pipe collectors. The dose collectors heat the water in the dark tanks and place it there until it is ready for use. Collectors of flat plates use a number of parallel tubes to heat the water, covered with a glass plate. The evacuated pipe pantographs use insulated access to water heating and are generally considered to be the most effective way, the launching of the start -ups are inmore.
circulation is another part of solar water heaters that may vary depending on the model. Circulation can be done using a direct system or indirect system that warms another liquid and then transmits that it is heated into water. Water can be transferred to the storage space either by pump or natural convection. Most installation companies insert an indirect circulation system if there is a risk of freezing liquid water, as is the case in colder climate.
The main advantage of the solar water heater is its ability to save energy costs. Depending on the time of year, weather conditions and the type of collector used, it may not be possible to supply water for the entire household using solar water heater. If this is the case, then a backup water heater can make a type of water, usually operated by a traditional electricity.
disadvantages of the Solar Water HeaterThe system is generally the cost of running and reliability of hot water. Installation costs can last up to five times higher than a high -efficient water heater running on traditional energy sources. Furthermore, to ensure that hot water is always available, another type of water heater may also be required. If the power failure occurs and the owner uses the pump to transfer water to the storage, it can be impossible.
