Morco Plate Heat Exchanger Kit ICB121302

The Plate Heat Exchanger Kit GB30 is a service component supplied by Morco Products for the Morco GB30 LPG SII boiler. The plate heat exchanger transfers heat between the primary circuit and the domestic hot water circuit, allowing the boiler to heat mains water on demand. This kit is the assembly used when the existing exchanger is scaled, blocked or leaking and requires renewal.

• Domestic hot water runs hot then cools, or fails to reach temperature while heating continues to work.
• Reduced hot water flow rate compared with the cold supply at the same outlet.
• Scale or debris visible at the exchanger connections, or restricted flow across the secondary side.
• Water weeping from the plate pack, gasket edges or union connections.
• Repeated overheat or DHW-related lockouts traced to poor heat transfer at the exchanger.

• Confirm the appliance model is the Morco GB30 LPG SII.
• Check the existing exchanger for scale, blockage or leakage before ordering, and confirm the fault is not elsewhere in the DHW circuit.
• Verify the part number ICB121302 against the label on the existing component or the boiler's parts listing.
• Isolate the appliance, drain the relevant circuits and check that seals and connections are prepared for refitting.
