Experiencing frequent drops in boiler pressure can indicate underlying issues that require attention or boiler repairs. Here’s a guide to understanding the causes and solutions for low boiler pressure:
1. Common Causes
- Water Leaks: Check for visible leaks in the boiler, pipes, or radiators. Even minor leaks can cause pressure loss over time.
- Bleeding Radiators: Air trapped in radiators can lead to pressure fluctuations. Bleeding radiators releases trapped air, restoring balanced pressure.
2. System Components
- Pressure Relief Valve: A faulty pressure relief valve may release water from the system, causing pressure drops. Inspect and replace the valve if necessary.
- Expansion Vessel: The expansion vessel absorbs excess pressure within the heating system. If faulty, it may fail to maintain optimal pressure levels.
3. Technical Inspection
- Boiler Components: Have a Gas Safe registered engineer inspect the boiler’s internal components, including seals, valves, and pressure sensors.
- Pressure Adjustments: Follow manufacturer instructions to adjust boiler pressure within recommended ranges. Over-pressurisation or under-pressurisation can affect performance.
4. External Factors
- Cold Weather: Temperature changes can affect boiler pressure. Monitor pressure during seasonal transitions and adjust settings accordingly.
- System Flushing: Consider power flushing the heating system to remove debris and improve water circulation, reducing pressure issues.
5. Professional Maintenance
- Annual Servicing: Schedule regular boiler servicing to maintain efficiency and identify potential pressure-related issues early.
