What is the main issue with a poorly balanced gravity circulation system?

In a gravity circulation system, the distribution of heat is heavily dependent on the balance of the system. When the system is poorly balanced, it struggles to provide an even flow of heating fluid (typically water) throughout the system. As a result, some areas may receive too much heat while others may not receive enough. This uneven heating can cause discomfort in a building, as certain rooms or spaces may be too hot while others remain too cold.

Moreover, when some areas are not adequately heated, it may lead to increased energy consumption as the heating system works harder to achieve a consistent temperature. However, the primary concern with a poorly balanced system is its inability to evenly distribute heat, which directly affects the comfort and overall efficiency of the heating system.
