Should the solar water heater discharge water in sunny but freezing weather?

In windy weather, it is necessary to ensure that the water heater is full of water to prevent the solar water heater from blowing down or even blowing off. In the cold winter, the water heater should be properly drained to prevent the water heater from being damaged due to freezing and expansion. In addition, it is necessary to clean the solar water heater regularly and replace the magnesium rod regularly to prevent excessive scale from damaging the water heater and pipes and affecting the use.

Precautions:

Before entering the winter, conduct a comprehensive inspection of the solar host and pipe fittings, and replace the damaged parts in time to prevent accidents in cold winter weather. Users who do not use solar energy in winter should ensure that the water tank is full of water to prevent the vacuum tube from exploding and the rubber ring from being damaged due to thermal aging caused by long-term air drying.

When the weather is extremely hot and the water temperature is extremely high, it is forbidden to add water immediately after using it, because adding water can easily cause the pipeline to burst. The best water supply time of solar water heater is two hours before sunrise in the morning or after sunset in the evening to ensure the service life of solar water heater.
