What it is
The Halstead 450997 is a plate heat exchanger used in Halstead ACE and Wickes Combi 82 gas boilers. It transfers heat between the primary circuit and the domestic hot water circuit, so the appliance can deliver hot water on demand. The plate pack is built from stacked stainless steel plates brazed together, with separate flow paths for each circuit.
Signs this part needs replacing
- Domestic hot water runs hot then cold, or temperature swings at the tap
- Reduced hot water flow rate compared with the cold supply
- Scale or sludge blocking the plate passages, often on hard water areas
- Water weeping from the plate pack or its connections
- Primary water contaminating the domestic hot water circuit
Before you order
- Confirm the appliance model is an ACE or Wickes Combi 82
- Check the serial number against the ACE FROM and TO ranges listed above
- Compare the part number on the existing component with 450997
- Inspect the system for sludge or scale, as contamination can damage a new exchanger
