What can be a consequence of air locking in a heating system?

Air locking in a heating system occurs when air becomes trapped in the pipes, preventing the proper circulation of water. As a result, one significant consequence is the prevention of water flow. This blockage disrupts the system's ability to heat effectively because hot water cannot circulate to radiators or heating surfaces, leading to cold spots and inefficiencies in the heating process.

When air pockets form, they can hold back the movement of the liquid, causing portions of the heating system to operate inefficiently or not at all. Thus, the system may struggle to reach the desired temperature and may require additional maintenance to bleed the air out, which is crucial for restoring optimal functionality.
