What can be a sign of a leak in a hot-water heating system?

In a hot-water heating system, a leak can manifest through multiple observable signs. Cold radiators can indicate that water is not circulating properly due to a leak, which prevents heat from reaching those radiators. Puddles of water near the equipment are a direct and clear physical sign of a leak, indicating that water is escaping from the system. Increased energy bills can also be a sign since a leak may require the system to work harder to maintain the desired temperature, leading to higher energy consumption. When considering these factors collectively, it becomes evident that all of these signs are interrelated and can point to the presence of a leak in the system. Therefore, recognizing any one of these indicators is essential for identifying potential issues in hot-water heating systems.
