What it is
The Heatline D020116523 is a plate to plate heat exchanger used in Heatline gas boilers. It transfers heat between the primary circuit and the domestic hot water circuit, allowing the boiler to heat hot water on demand. The unit is built as a stack of plates that form alternating channels for the two water paths.
Signs this part needs replacing
- Domestic hot water runs hot then cold, or fails to reach temperature
- Reduced hot water flow rate compared with the cold supply
- Scale or debris blocking the plate channels, often worse in hard water areas
- External leaks or weeping from the plate gasket edges
- Primary and domestic hot water circuits cross-contaminating
Before you order
- Confirm the boiler model and GC number match the fitment list above
- Check the existing heat exchanger for the D020116523 number
- Inspect the plate stack and connections for scale, sludge or leakage before ordering
- Verify that the fault is not caused by a diverter valve or sensor before replacing the heat exchanger
