When using a solar water heater, it is very important to ensure safety. Here are some common safety considerations:

1. Prevent the tank from dry burning                           

Avoiding empty tank exposure: The solar water heater tank should always keep a certain amount of water, especially in the summer when the sun is strong. If no water is in the tank, the collector tube may be damaged due to overheating and even cause accidents.       

Regularly check the water level: Some solar water heaters are equipped with a water level display device, users should periodically check the water level of the tank to ensure that the tank is full of water or maintain a reasonable water level.

2.Prevent  high-temperature burns                               

Adjust the water temperature: In summer, the water temperature inside the tank may rise very high (even up to 90℃). When in use, turn on the cold water first and then gradually turn on the hot water to avoid using hot water directly. Installing a mixing valve is also an effective safety measure. Adjust the ratio of cold water to hot water to ensure the water is at the right temperature.   

Child Safety：If there are children in the house, extra caution should be taken to prevent them from directly accessing the hot water taps, as this could lead to burns.                                             

3. Proper Use of Electric Heating                           

Temperature Control: When using electric heating, set a reasonable temperature (usually between 50°C and 60°C) to save energy and avoid overheating, which could result in burns.                      

Electrical Safety: Ensure that the electrical components, such as wires and heating elements, are in good condition to prevent risks of short circuits or electric shock. If the water heater is not in use for a long period, it's advisable to disconnect the power. Avoid Handling with Wet Hands: Do not touch the control panel or power switch with wet hands to reduce the risk of electric shock.

4. Lightning Safety                                           

Lightning Protection: Since solar water heaters are installed on rooftops and are susceptible to lightning strikes, ensure the heater is equipped with lightning protection or choose a model with built-in protection, especially in areas prone to thunderstorms.

5. Reinforcement During Typhoons or Strong Winds            

Securing the Equipment: Before and after periods of strong winds or typhoons, check that the solar water heater is securely fastened to prevent it from being blown off. Additional reinforcement measures may be necessary to avoid damage to the equipment or injury to people.

While solar water heaters are eco-friendly and energy-efficient, their safe and effective use requires careful attention to water temperature control, electrical safety, and regular maintenance.
