Solar water heater maintenance: what you need to know

Maintaining a solar water heater is important to ensure that it operates efficiently and effectively. Here are some tips for solar water heater maintenance:

Regularly clean the solar collectors: The solar collectors on the roof of your home will collect dust, debris, and other particles over time. It is important to clean them regularly to ensure that they can absorb as much sunlight as possible. Use a soft brush and water to gently remove any debris from the surface of the collectors.

Check the fluid levels: Solar water heaters use a fluid, such as antifreeze or water, to transfer heat from the collectors to the hot water storage tank. Make sure that the fluid levels are at the appropriate level and that there are no leaks in the system. If you notice a leak or a decrease in fluid levels, contact a professional for repairs.

Inspect the pressure relief valve: The pressure relief valve on your solar water heater is designed to release pressure if it builds up inside the tank. Check the valve to make sure it is working properly by lifting the lever slightly to allow some water to flow out. If there is no flow or if the valve is stuck, contact a professional for replacement. Here we recommend a pressure and temperature relief valve, that could release when pressure reaches 6 bar or temperature up to 90 ℃.

Inspect the water tank and pipes: Inspect the hot water storage tank and pipes for any signs of damage, such as cracks or leaks. If you notice any issues, contact a professional for repairs.

Schedule regular professional maintenance: It is recommended that you have your solar water heater professionally serviced once a year. A professional can perform a thorough inspection and make any necessary repairs or adjustments to keep your system running smoothly. We recommend replace the magnesium rod inside the hot water storage tank once half year. 

By following these maintenance tips, you can help ensure that your solar water heater operates efficiently and effectively for years.
