Generally speaking, it takes 15 to 30 minutes to thaw after entering tropical areas. Turn on the hot water tap and turn on the tropics at the same time. When the hot water comes out, turn off the tap. The maximum heating temperature in the tropics is 70 degrees. The power is 25 watts per meter.
According to experience, some citizens can open the hot water tap of the solar water heater when the temperature is below zero and let it drip slowly to keep the solar water flowing no problem. prevent solar pipes from freezing.
In winter, if no one lives in the house, the exterior pipes must be drained and the main water tap must be closed. The water mixer handle must be in the hot water and open position. Even in harsh winter, if the vacuum tube is air-dried without water for more than 1 hour, it cannot be refilled to avoidand the tube does not burst.

Notes
1 When installing a solar water heater, there may be a smell of dust or oil in the water. Hose when you use it for the first time, you can first open the faucet and remove the debris.
2. The water stored in the solar water heater should be discharged regularly depending on local water quality conditions. Drain time can be selected in the morning when the sensor temperature is lower.
3. The surface of the solar water heater should be wiped regularly depending on the amount of dust in the area. It can be cleaned when it rains. Keeping the water heater surface clean can get higher heat. collection efficiency.
4. When hot water is not used for several consecutive sunny days, the hot water temperature will be very high. When usingof the solar water heater, please turn on the cold water first, then the cold water. hot water to avoid burns.
5. There is usually a filter device at the outlet end of the faucet. Scale and debris in the water line accumulate on this screen. It should be removed and cleaned regularly to increase water flow. smooth the flow.
How to prevent solar water heaters from freezing in winter?
Anti-freeze methods of solar water heaters in winter include insulation layer to prevent freezing, installation of electric heating tape and draining to prevent freezing .
1. Insulation layer to prevent freezing
The water pipes of solar water heaters can be protected from freezing by adding an insulation layer. This method of antifreeze of the insulating layer is the most basic method. Most solar water heater water pipes will be insulated whenur installation, usually at around minus 10°C in winter, they will not freeze or freeze.
2. Install electric heating tape
For some locations with extremely cold winters, a single layer of insulation may not be able to effectively prevent outdoor water pipes from freezing, so you must install a layer of insulation. If necessary, electric heating tape can be added along the pipe. Use electric heating and insulation to solve the problem of frozen pipes. And this way it can also ensure that when using hot water, what is released is hot water, ready for use.
3. Drain and Antifreeze
You may not be familiar with antifreeze. In fact, the principle is very simple. This involves draining the water from the outside water line. of the solar water heater after each use. Let it go so that only air remains in your mouth.yau. There is no water in the pipe, so naturally it will not freeze, let alone the pipes. This is used to prevent freezing.
Precautions for using solar energy in winter
1 Try not to use water in continuous rain and snow. low temperature
2. Clear snow from solar vacuum tubes in time
If you encounter snowy weather, the snow on solar vacuum tubes should be cleared in time. the sun. Light irradiation on vacuum tubee affects heat absorption. It must be removed in time, let alone wait for the snow to become thick, freeze and freeze the vacuum tube.
3. Windproof
The northwest wind usually blows in winter, and sometimes the wind is very strong if the solar power is not installed stably and there is no of water in the water tank. , it is very likely that the wind will blow. If it is blown by the wind, if it is on top of a building, it can be knocked over and cause injury.
1. Use insulation materials for pipes
For solar pipes, it is best to wrap them with foam, cotton and linen fabric, plastic, etc. so that can play the role of heat preservation.
2. Turn on the electric heating tape
General solar water heaters have electric heating tapes. When the temperature is below zero, remember to turn on theelectric heating tape, which can be. Alright. Protect solar water heaters from freezing.
3. Antifreeze by water drops
As long as the water continues to flow, the possibility of freezing is very low. Before going to bed at night, you can turn on the hot water tap slightly and let the water drip to ensure that water flows through the water pipes. Remember to put a bucket to collect the water so you can use it the next day. Don't waste water.

Daily maintenance of solar water heaters: < /p>
1. When hot water is not used for several consecutive sunny days, the hot water temperature will be very high. When using the solar water heater, please. turn on cold water first, then hot water to avoid burns.
2. There is usually a filter device at the outlet of the robinet. Scale and debris in the water line accumulate on this screen. It should be removed and cleaned regularly to increase the amount of water and smooth. exit.
3. In winter, it is very common for pipes to freeze. If it turns out that the pipe has frozen but is not yet cracked, it can usually be cleaned automatically after the temperature rises. You can also use a hair dryer to blow out the water pipe, or wrap a towel around the water pipe and then slowly pour it with warm water. Do not cook it on fire, hit the pipe, or scald it with boiling water. This will cause the pipes to burst. Multiple freeze blockages can easily cause pipes to freeze and crack. Pipe insulation measures must therefore be reinforced.
4. Solar water heaters should be cleaned, inspected and disinfected on average every two to three years. THEUsers can also do some disinfection work themselves, such as purchasing chlorine-containing disinfectants and adding them. At the water. Pour it into your mouth, soak it for a while, and then release it, which can achieve a certain disinfectant effect.
5. Solar water heaters need to be cleaned inside the vacuum tube every two to three years on average to prevent scale from forming inside the vacuum tube and affecting the heat absorption effect.
6. If the solar water heater is equipped with a special instrument, please pay attention to lightning and electricity protection. Do not take a shower and unplug the electric heater during lightning.
