Heath experts recommend: solar water heating cannot be directly consumed

Today, solar water heaters are becoming increasingly popular; some families use heaters and cook hot food, boiling water for drinking. The Municipal Health Department's health education specialists have reminded the public that this practice is bad for their health. Municipal Public Health Board health education specialists state that solar hot water is not potable. Although the water entering the water heater is potable tap water, the metal used to make the water heater piping generally does not comply with kitchen material standards that strictly limit the content of harmful substances. Water heater pipes may contain excessive cadmium, manganese, arsenic, lead, and other metal poisons. In the long-term heating process, the poison will dissolve in the water. This hot water, used for washing, bathing, and other topical purposes, is generally not a problem. If used for long-term cooking, boiling, or drinking, it will eventually cause harmful damage to human health. Substances such as mercury, cadmium, and lead can inhibit the activity of thiol-containing enzymes, reducing protein synthesis and hindering organism growth and development. Long-term consumption of water containing harmful minerals or ions can lead to Alzheimer's disease, hypertension, arteriosclerosis, and developmental disorders and illnesses in children; in severe cases, it can cause fetal malformations in pregnant women.
