In this article, we explore the various causes that can lead to insufficient circulation in a boiler, a common problem that can significantly compromise the efficiency and operation of the heating system. In addition to the presence of dirt in the radiators, a frequent cause of this problem, it is also important to consider the possibility that the thermostatic valves of the radiators are all closed or blocked.
Typically placed under the boiler, it’s a tap that acts as a bridge between the water supply and the heating circuit. It’s used to charge the system to a pressure of 1.2bar / 1.5bar.
One of the most common problems in domestic boilers is the flame block error. This occurs when, during the ignition phase, the detection glow plug does not detect an adequate flame value. Consequently, not sensing the burner on, the boiler locks after a few seconds.
