Why is my boiler losing pressure?

Understanding Boiler Pressures

Boiler pressure is the balance of water and air within your boiler system. This pressure is critical for the proper operation of your heating system, which delivers hot water to your taps and radiators.

When a boiler is on, the appropriate pressure range is usually between 1 and 2 bars. If the pressure falls below this threshold, your heating system's performance may suffer.

Common Causes for Boiler Pressure Loss

Leaks in the system

Leaks are the most prevalent cause of pressure loss. Some of the signs you can look for include water stains, wet areas, or puddles near your boiler and pipes. These signs suggest that water is leaving from the system, causing the pressure to decrease.

Faulty Pressure Relief Valve

The pressure release valve is a safety device that keeps your boiler from being overly pressurised. A malfunctioning valve can cause a loss of pressure. If you find water leaking out of the discharge pipe, it might mean that the pressure release valve isn't working properly.

Air in the system.

Air can become trapped in the boiler system, lowering efficiency and resulting in pressure decreases. To remove air from the system, bleed the radiators. This easy procedure can restore proper pressure in your boiler. 

Maintaining boiler pressure is critical for the proper operation of your heating system. Regular inspections and maintenance can help to prevent many common problems. However, if you are unsure about any repairs, don't hesitate to contact a professional.
