There are currently three types of solar water heaters on the market: solar drying type, circulation type, vacuum tube type and heat pipe type. The difference between them is the different heat-absorbing elements. The sensual type heat absorbing element is integrated with the heat storage element, which has low thermal efficiency and poor thermal insulation. This is the simplest type; the circulating type heat absorbing element is made of pure copper plate core and is separated. of the water storage tank. It has a high heat absorption rate, but the heat absorbing element is also a heat dissipation element with poor thermal insulation and cannot be used in winter. thermal emissivity, has good thermal insulation performance, and can be used in winter; the heat pipe type plate core is combined with the vacuum tube, the performance isalso have very good, but the size is large, the production cost is high, and the price is higher.
1. What water temperature can the solar water heater reach?
Solar water heaters are divided into vacuum tubes and flat plates, and the temperatures are also different:< /p>
1. Evacuated tube water heater: The water temperature can reach around 60°C in summer and around 45°C in winter. It cannot adjust the temperature by itself. If it is continuously heated, it uses more energy. than ordinary electric water heaters.
2. Flat Panel Solar Water Heater: The water temperature can reach over 90℃ in summer and around 70℃ in winter. The water temperature of this type of water heater can be adjusted by itself. can save 70-90% energy compared to ordinary water heaters.
2. What problems should you pay attention to when using floor water heatersareas?
1. If you experience water shortage while using solar water heaters, remember to refill water immediately. . Since the temperature inside the solar water heater tube will rise up to 2500°C during the air drying period, if the water is filled immediately, the tube may explode.
2. If there is an auxiliary heat source, it is recommended to regularly check whether the auxiliary heat source can work normally. When using it, you should also consider whether the protector is reliable. After starting the water heater, the water content in the tank cannot be less than 50%.
3. When installing heating tape on a solar water heater, pay attention to whether the quality of the heating tape is acceptable to avoid unnecessary safety risks. In addition, when the voltage is unstable, the electric heating tape cannot be used.be used to avoid certain safety accidents, otherwise it would cause inconvenience and problems.
