If it is broken, it can be replaced. Check the power cord or replace the power cord directly. Under normal circumstances, the electric heating tube is not easy to burn. And if it still does not work after replacing the power cord, you will have to go to the after-sales service and have it repaired.
The following factors mainly affect the heat gain of solar water heaters in winter:
1. Heat collection area and heat collection performance
Generally speaking. , solar heat capture The larger the surface area, the greater the heat gain and vice versa. When the heat collection area is the same, the heat collection performance of the vacuum tube is an important factor affecting the heat gain capacity of the solar water heater. At present, in terms of heat collection performance of vacuum tubes in China, the performanThese most notable are undoubtedly the three high “solar core” vacuum tubes produced by Huangming Group, whose heat collection performance is far superior to that of common vacuum tubes on the market. walk.
2. The thermal insulation capacity of the water tank
In addition to the heat collection capacity, the solar water heater also depends on its thermal insulation capacity. The thickness and material of the insulating layer of the water tank are important parameters that affect the insulating capacity of the water tank.
3. The tilt angle of solar water heaters
Due to China's vast territory, geographical differences between north and south, and differences in the angle and intensity of solar radiation, Solar water heaters should have the best golden tilt angle. According to China, judging from the latitude of the continent, 33° to 55° is the design angleoptimal.
The solar water heater pipes are not clear. The water inlet hose is connected backwards. Does the water come out when the water is turned on?
The cold water pipe is connected to the cold water outlet.
Solar water heaters have two pipes. Generally, the hot water outlet is on the left and the cold water inlet is on the right. When installing, connect the cold water pipe to the cold water. the inlet and the hot water pipe to the hot water pipe. The mouth is closed and the two water pipe interfaces will also be marked.
In addition to the upper and lower pipes, the solar water heater also has an overflow pipe, which is mainly used for drainage. When the water heater is full, the excess water will be discharged through the overflow pipe and then simply turn off the water tap.
Operating principle of solar water heater
Solar water heaters are divideded into evacuated tube solar water heaters and flat plate solar water heaters based on their structural shapes. main ones, representing 95% of the domestic market share.
Home evacuated tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into thermal energy mainly relies on vacuum tubes which use the principle that hot water is used. floats and cold water sinks, causing microcirculation of water to obtain the required hot water.
Solar energy generally refers to the radiant energy of sunlight. Solar energy is a renewable energy source in a broad sense, solar energy is the source of many energies on earth, such as wind energy and biomass energy. , tidal energy and potential energy of water, etc.
The basic methods of using solar energy can be divided into four categories: using light and heat, using light and electricity, using light and chemicals and use of light and biology. Among the four types of solar energy utilization methods, the technology of converting light into heat is the most mature, and the products are the most mature. For many, the cost is relatively low.
Under the side of the water tank is the interface of the inlet and outlet pipes. You can directly connect the water pipe to the bathroom at home. Water supply and hot water are shared. .
On the side of the water tank are the interfaces of the ventilation pipe and the overflow pipe, which are connected by a tee. The overflow pipe is connected to the house below. Once the water is fillede, the overflow will remind. you must turn off the water supply tap. Simply connect a piece of vent pipe to the top of the tee.
The upper and lower joints cannot be connected in series and must be disassembled.
The following is a reference image. There are some differences in the layout structure of the water tank interface. Some overflow ports and vents are shared, others are separate, and some overflow pipes extend from the internal water line. at the bottom of the water tank to the top of the water tank liner.
