Ideal Response 80 100 120 FF80 Henrad CC Boiler Pressure Relief Valve 075178

Product Overview

The Ideal Boiler Pressure Relief Valve (Part Number: 075178) is a pressure safety component intended for selected Ideal Response and Henrad CC boiler systems.

The pressure relief valve (PRV) protects the boiler's sealed central heating circuit against excessive pressure by allowing water to discharge when the specified pressure limit is reached.

Correct operation of the valve is important for maintaining safe pressure conditions within the heating system.

ℹ️ Product Condition Options:

This part may be available in New or Refurbished condition. Please select your desired option from the dropdown menu above. Any refurbished pressure relief valve must be professionally inspected and tested to confirm that it meets the required operating and safety specifications before installation.

Technical Insight & Common Failure Symptoms

The pressure relief valve is a mechanical safety device designed to protect the boiler's heating circuit from excessive pressure.

Under normal operating conditions, the valve remains closed. When the system pressure reaches its specified relief setting, the valve opens to discharge water through the safety discharge pipe.

Over time, pressure relief valves may be affected by internal contamination, deterioration of sealing components, corrosion or repeated operation.

Possible symptoms that may indicate a pressure relief valve or associated heating system problem include:

• Water dripping or discharging from the pressure relief pipe.

• Boiler pressure dropping after water has been discharged.

• Continuous leakage from the valve outlet.

• Pressure relief valve failing to reseal correctly.

• Repeated discharge caused by excessive system pressure.

• Difficulty maintaining normal central heating system pressure.

• Visible corrosion, damage or deterioration around the valve.

These symptoms do not necessarily confirm a faulty pressure relief valve, as similar problems may result from expansion vessel faults, excessive filling pressure or other heating system components. Correct professional diagnosis should be carried out before replacement.

Compatibility

This part (MPN: 075178) is associated with selected Ideal Response and Henrad CC boiler systems.

Please verify the exact boiler model, GC number, part number, valve pressure rating and connection specifications against the manufacturer's technical documentation before ordering to ensure correct fitment.

Safety Advice

Boiler pressure relief valves are safety-critical components within a pressurised heating system and 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 depressurised in accordance with the manufacturer's servicing instructions. Never block or restrict the safety discharge pipe. The correct valve pressure rating must be maintained, and all required pressure, leakage and operational safety checks must be completed before the boiler is returned to service.
