Water heaters are one of the bathroom items we can't do without. When we choose, many people don't know how to choose the right one for their own home. So do you know about homemade solar water heaters? Many people don’t know how to do it because they don’t understand it. So what do you need to pay attention to when using solar water heaters? Today, Xiaobian will take a look at the methods and precautions for using solar water heaters !
Homemade solar water heater method:
1. This installation uses the water inlet solenoid valve of the washing machine. The parameters are: water inlet G3/4 inches (ie external thread of Dg20), water outlet is Φ10mm, working voltage is AC220V, working pressure is 0.02~0.08MPa. The price of the washing machine parts store is only about 15 yuan.
2. Although the water outlet of the solenoid valve is a straight threaded port of Φ10mm, it can be directly connected with the aluminum-plastic pipe fitting of Dgl5. Since the water outlet is a hard plastic pipe, when connecting with the aluminum-plastic pipe fittings of Dgl5, one should apply a little smooth oil on the aluminum-plastic pipe fittings, and the other is to soak the water outlet of the solenoid valve in boiling water for two minutes, so that When connected.
3. Since this type of solenoid valve does not avoid the return water function, when the water pressure of the water outlet is greater than the water pressure of the water inlet (the tap water is stopped), the water will reverse the activity when the power is not applied, so it is necessary to use it in pairs. , the water outlets of the two solenoid valves are docked, the inlets of the two solenoid valves, one for the water inlet and the other for the water outlet.
Solar water heater use precautions
1, water injection time. Pay attention to the water injection time when using the solar water heater. Because when the weather is particularly hot, the water temperature inside the Huangming solar water heater water pipe is particularly high, and when the water is used immediately after the water is used, it is easy to build.
The bursting of the pipeline occurs, the service life of the solar water heater in crisis and the safety of the personnel. Therefore, the best water injection time for solar water heaters is two hours before the sunrise in the morning or the sun in the evening. Water injection during this period will ensure the service life of the solar water heater and the safety of the users.
2. Avoid dry burning. Generally speaking, domestic water heaters are equipped with an electric auxiliary heat system, and the electric auxiliary heat system generally increases the overall temperature of the water in the full water tank by about 3-5 degrees per hour. If the phenomenon of dry burning of the Huangming solar water heater is likely to cause a fire, it will endanger people's lives and property. Therefore, in the use of solar water heaters, the function of electric auxiliary heat must avoid the occurrence of dry burning, thus effectively avoiding accidents, ensuring the personal safety of the users, and the safety responsibility is greater than everything else.
3. Operate live equipment. When using a solar water heater for showering, it is strictly forbidden to spray water to the electrical parts, especially when using the Yuba. At the same time, during the shower, it is strictly forbidden to operate the parts of the Minghuang water heater with wet hands. Our correct approach is to cut off the heat-assisted system and the anti-freezing live system power supply of the solar water heater before the shower. It is strictly forbidden to use the leakage protection plug as a switch, and it is strictly forbidden to start the appliance frequently.
Solar water heaters are a choice that many families will choose. When we choose, we need to know how to use them correctly. The above is the self-made solar water heater method and the precautions for use introduced by Xiaobian today. It is over here.
