First of all, there are quality problems. There are holes in the foam insulation of the water tank and the insulation is not good. Inspection method: Measure the water temperature in the water tank before sunset in the evening and before sunrise in the morning. Look at the temperature difference: 5-8 degrees in winter and less than 5 degrees in summer
This is normal (the test requires a full tank of water, otherwise it may not be accurate)
< p> Second, water leaks. Automatic water replenishment when the water level is insufficient will affect the water temperature.Third, there is a usage problem. Everyone's water usage is different and your home's water usage is important. That is, your solar energy is too weak.
Fourth, the lighting angle is incorrect and the heating speed is slow. There is a cover. Lighting timeis short and the temperature rises slowly
There are many reasons, but here are the most common
The water heater has a big temperature difference between morning and evening because it There is a problem with the water tank or vacuum tube, that is, it is not insulated, if it is not a problem with the production quality of the product, it means that the production standard is low. There is no easy way to resolve this problem. If that doesn't work, you need to replace solar power. I suggest you choose Huangming solar power. It is easy to use in winter.
