Is water boiled with an immersion heater safe to drink?
Disease description:
I don’t have an electric kettle at home—only a “quick-heater” (immersion heater). Is water boiled using a “quick-heater” safe to drink?

Water boiled with an immersion heater (also known as a “quick-boil” device) is safe to drink, but it should not be consumed regularly. Water heated this way often develops an unpleasant odor, and—due to electrolysis occurring during heating—it becomes electrolyte-enriched water. Long-term consumption may adversely affect health. Moreover, using an immersion heater poses safety risks, including potential electric shock. We recommend using a dedicated electric kettle for boiling water instead.
