TIL why you're not supposed to cook or drink hot tap water - it's the lead (and other heavy metals) (www.epa.gov)

Hot water dissolves lead more quickly than cold water and is therefore more likely to contain greater amounts of lead. Never use water from the hot water tap for drinking, cooking, or making baby formula.

Yeah the real reason is that the inside of a hot water storage tank is nasty. Because of the way heat flows up, the hot water fills from the bottom and drains from the top. All the sediment and dirt and minerals collect at the bottom.

Depending on the temperature setting they are also a prefect breeding ground for legionella
