Worcester Greenstar 9i 12i 15i ErP System CH Flow Pipe 87161064280

Product Overview

The Worcester Bosch Greenstar Central Heating (CH) Flow Pipe Assembly (Part Number: 87161064280) is a hydraulic component designed for selected Worcester Bosch heating systems.

The CH flow pipe forms part of the boiler's primary heating circuit, providing a connection for the circulation of heated water through the appliance.

The pipe assembly helps direct heated water towards the central heating system, supporting normal water circulation during boiler operation.

Correct installation and sealing are important for maintaining the integrity of the heating circuit and preventing water leakage.

ℹ️ Product Condition Options:

This part may be available in New or Refurbished condition. Please select your desired option from the dropdown menu above. Refurbished components should be professionally inspected for damage, corrosion, internal restrictions and leakage before installation.

Technical Insight & Common Failure Symptoms

The central heating flow pipe is a hydraulic component that forms part of the boiler's water circulation arrangement.

During heating operation, water heated within the boiler travels through the primary circuit and towards the central heating system. The flow pipe provides part of the internal connection required for this circulation.

Over time, pipe assemblies may be affected by corrosion, mechanical damage, internal restrictions or deterioration of associated connections and seals.

Possible signs that the CH flow pipe or associated hydraulic components require inspection include:

• Water leakage around the pipe or its connections.

• Visible corrosion or deterioration of the pipe assembly.

• Cracks, deformation or physical damage.

• Damaged or worn connection surfaces.

• Loose or insecure hydraulic connections.

• Heating system pressure loss associated with leakage.

• Restricted water circulation caused by internal obstructions.

These symptoms do not necessarily confirm a faulty CH flow pipe, as similar problems may result from damaged seals, circulation faults or other hydraulic components. Correct professional diagnosis should be carried out before replacement.

Compatibility

This part (MPN: 87161064280) is associated with selected Worcester Bosch Greenstar System ErP boiler systems.

Please verify the exact boiler model, GC number, original part number, pipe configuration and connection arrangement against the manufacturer's technical documentation before ordering to ensure correct fitment.

Safety Advice

Boiler central heating flow pipes and associated pressurised hydraulic components should only be inspected, removed or installed by a suitably qualified and competent heating engineer.

Always isolate the appliance and allow the heating system to cool before carrying out any work. The heating circuit must be safely isolated and depressurised before removing the pipe assembly. Follow the manufacturer's servicing instructions and complete all required pressure, leakage and operational safety checks before returning the boiler to service.
