I don't mind an unnamed user editing hot out of hot water heater but their choice of replacing hot with cold results in the rather uncommon construction of cold water heater which far worse than even water heater which should be preferred. They might find hot water heater to be an oxymoron but it is rather common and doesn't sound as unnatural as cold water heater does.
