Explanation of Hot Water Heating Systems | Hunk

In a gravity system, the circulation of water is due primarily to thermal and density differences between hot and cold water. As water heats, it expands, displacing the cooler and less dense cooler water throughout the system. If you are thinking that water expands as it gets colder, it does, but only as it approaches freezing temperature.
