Ideal / Morco GB24 Series 11 Main Heat Exchanger – Refurbished | Part No. 175615

The main heat exchanger is the primary component responsible for transferring combustion heat from the burner into the central heating and domestic hot water circuits. On an Ideal or Morco GB24 Series 11 boiler, a failing main heat exchanger typically presents as reduced heating output, extended heat-up times, error codes relating to overheating, or visible signs of flue gas leakage caused by pinhole corrosion or cracking in the exchanger body. Left unresolved, a compromised heat exchanger can allow combustion products to contaminate the water circuit — making prompt replacement essential. The Ideal / Morco GB24 Series 11 Main Heat Exchanger (Part No. 175615) is the correct OEM replacement for restoring full boiler output and safe operation.

This is a professionally refurbished genuine Ideal main heat exchanger. Each unit is fully inspected externally and internally — the heat exchanger body, end caps, flow and return connections, and all associated seals are assessed and replaced as required. The exchanger is then pressure-tested to confirm structural integrity and leak-free performance across all joints and connections before dispatch. You receive full OEM-spec thermal performance at a substantial saving over a new replacement unit.
