If the solar water heater is frozen, the quick way to defrost it is to pay attention to the water filling time, ventilation antifreeze method, drip antifreeze method drop, etc.
1. Pay attention to the time when the water supply is selected.
When using solar water heaters in winter, the water filling time should be determined according to the weather situation. . If the temperature outside is above freezing, you may consider adding water that night.
