Some of this depends upon the mineral content of your water. If you have softer water then running hot water for food or beer probably isn't a big deal. However for those of us not in that situation it's terrible water. When I flush the water heater out comes rocks about the size of aquarium gravel. The water from the hot water heater doesn't taste good and the mineral content changes the flavor of coffee and tea. Beer too, if one were to use it for brewing.
