What it is
The Andrews heat exchanger and seals set, part number 5140173, is a heat exchanger assembly supplied with its seals for Neoflo hot water appliances. It transfers heat from the primary circuit to the domestic hot water, and the seals cover the connection points on refitting. It is listed for the Neoflo SC25 range.
Signs this part needs replacing
- Domestic hot water output has dropped or become inconsistent
- Water weeping or staining around the heat exchanger connections
- Scale or debris build-up restricting flow through the exchanger
- Kettling or knocking noises from the appliance during a draw-off
- Repeated lockouts or temperature faults traced to heat transfer
Before you order
- Check the appliance data plate to confirm the Neoflo model and variant
- Confirm the existing heat exchanger matches the 5140173 part number
- Inspect the seals and connection faces before refitting the new assembly
- Allow for isolation of the water and primary circuits before work begins
