Why Does Your Boiler Pressure Keep Dropping?
As the temperature decreases, households increasingly rely on their boilers for warmth. However, boilers can exhibit temperamental behaviour over time, leading to pressure loss due to leaks or faults. Consequently, issues may arise with hot water and central heating. If you’ve observed a drop in your boiler pressure, it’s crucial to address the problem promptly. In this post, we’ve compiled reasons behind boiler pressure drops and effective solutions.
Understanding boiler pressure
Boilers maintain a specific pressure to ensure the proper functioning of the system throughout a property. This pressure fluctuates with temperature changes, providing access to both hot and cold water. Effective boiler operation requires it to stay within a designated pressure range, typically managed by the boiler’s expansion vessel, usually between 0.7 bar and 2.5 bar.
checking low boiler pressure
Indications of low boiler pressure include a loss of hot water. If you notice such symptoms, consulting your boiler’s manual is recommended. Each boiler has different pressure gauges, which may be challenging to locate. Diverse boilers also exhibit varying indicators of pressure drops, necessitating an understanding of display meanings. Boiler manuals are often available online for reference.
identifying causes of pressure loss
Pressure loss generally results from a leak within the system, often around radiator valves. While other issues may cause pressure drops, leaks are the most common and challenging to detect. Corrosion in pipes, leading to small leaks, is a frequent cause. Locating these leaks is difficult, especially when they are small and go unnoticed until pressure loss occurs.
