Explanation of Hot Water Heating Systems | Hunk

A gravity hot water heating system is the oldest and simplest system to heat homes. It is also the least efficient. 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.

Mar 12, 2009· The strange thing is that our heating switches off at 10:30 pm, yet at 6:30 the following morning (before the heating comes on again), the water is still extremely hot. It's a gravity fed system, but I cannot understand why it doesn't cool down overnight - it never used to stay hot all the time.

When you heat water in a boiler, it will rise up into the pipes because it's lighter that the relatively cold water in the system piping. That colder water, in turn, falls back down into the boiler (by gravity), and before long, you have a Ferris wheel flow of warm water moving freely from the boiler to the radiators.

Your description of the black stuff sounds exactly like the stuff I had in my hydronic system pipes, near the boiler. The problem was that the expansion tank, mounted very near the boiler, which is the type with a rubber diaghram, had suffered a failure of that diaghram and some of the rotted rubber, in gooey and granular form had found its way into the circulating water in the pipes.
