just to clarify, they are saying your water heater is likely putting in containments when you get hot water out of the tap. they are not saying you shouldnt heat water.

Is it okay to use water from the hot-water tap for drinking, cooking, or making baby formula?
Hot water generally comes from a hot-water heater that may contain impurities that should not be ingested. Some of these impurities might be metals from household plumbing that are concentrated in the heating process. Additionally,these impurities from household plumbing dissolve more rapidly in hot water, causing the amount of impurities to be higher in hot water.
