Able to take cold water.
Sometimes, when the sun is out at noon, we find that only 20% of the water remains in the solar water heater, or even less. The remaining water has already boiled. Otherwise, there may not be enough water for bathing at night. If water is supplied, there is a risk of pipe explosion. In this case, it is also possible to get into the water.
After the solar water heater is installed, the temperature inside the vacuum tube exceeds 200° when there is no water supply. At such a high temperature, when cold water enters, the vacuum tube bursts due to sudden shock. cooling and shrinkage. Therefore, to ensure that everything goes well, the advice given by the installation master and the manual is to wait for the sun to set for an hour, or to wait for the sun to rise before setting. put in the water.
Remarks on the use of solar energy:
1 During the installation process of solar equipment, there may be stains or oil stains on the inside water pipes. , so after installation, you must open the faucet and drain the internal residue to ensure normal use. In addition, when using solar equipment every day, pay attention to hygiene and cleanliness to ensure the surface is clean.
2. If the solar power has not been used for several days and the weather is good, the water inside the solar power will become very hot. If it is suitable for the use of hot water, special precautions must be taken. take to avoid being burned. The hot water is scalding. In addition, a filter will be installed at the tap water outlet. Over time, stains will accumulate and need to be treated in time.
3. After the equipment isIf the product has been used for about 2-3 years, it should be carefully inspected to ensure that there are no too many stains left, otherwise it will affect daily use. If you plan to disinfect solar energy, you can pour disinfectant into solar energy and then pour it to achieve a strong sterilization effect.
When there is enough sun in summer, the temperature of solar water is very high, sometimes even boiling. There is no particularly effective way to solve the problem of overheating water. Typically a mixer tap and mixer shower are installed, adjustable in use and some cold water is mixed on site.
What you are talking about now is that there will be no water when the cold water is turned on. I haven't been to the venue to see it, so I can only speculate. The cold water pressure may be too low. If you turn on the cold water, the cold water cannot mix and the hot water flows into the cold water pipe. . . . Close the solar hot water valve and turn on the cold water separately to see if the cold water is very small.
If you turn on the cold water alone and there is no problem with the water pressure, the water mixer may be broken. You need to contact the Haier after-sales service center and ask the master to help you take. a glance. If you want to do it yourself, installing a check valve in the cold water line can solve the problem of hot water backing up. but. . . . The cold water pressure is low, so it is always difficult to mix the water. If the pressure on both sides is close, the mixed water will be easier to mix.
