Self-gravity circulation systems

Self-gravity circulation systems, also called gravity circulation systems, are simple and energy-saving ways to ensure the circulation of hot water in hot water distribution systems without the need for a pump. The principle is to use the natural movement of warm water, which is less dense and therefore lighter, to create a natural flow in the distribution systems.

The operation of the self-propelled circulation system is based on the differences in the density and temperature of the water in the system. A heating source, for example a boiler, is placed in the upper part of the system, which heats the water. Warm water has a lower density and rises, causing cooled water from appliances to flow down. This natural circulation cycle allows the hot water to reach the appliances faster and minimizes the time we have to run the water until the hot water arrives.

Self-propelled circulation systems are often used in households and small buildings, where there is no need for a large circulation of hot water and it does not make sense to install an electric pump. These systems are energy efficient because they do not need additional electricity to drive the pump, and at the same time ensure convenient and quick access to hot water in different places in the house.

In some cases, a combination of a self-propelled circulation system with a small pump to support circulation can also be used if more pressure is needed or to ensure better circulation over longer distances. Overall, however, self-propelled circulation systems offer a simple, reliable and economical way to transport hot water in hot water distribution systems.
