What it is

Signs this part needs replacing
- Domestic hot water runs cold or fluctuates between hot and cold at the tap
- Reduced hot water flow rate compared with the cold supply
- Water weeping or tracking from the plate stack or its connections
- Scale or debris blocking the plate channels, causing poor heat transfer
- Whistling or kettling noise from the heat exchanger when a hot tap is opened
