The buildup or scaling of mineral (calcium) deposits in a solar water heating system due to the high mineral content found in domestic water or hard water can be avoided by using water softeners or by circulating a mildly acidic solution (like vinegar) through the collector or domestic hot water loop every 3-5 years, or as necessary depending on water conditions. 

2. Corrosion
