What it is
A 30 plate 'long' plate heat exchanger (PHE) supplied by Caleffi HIU for use on the hot water side of a heat interface unit. It transfers heat from the primary circuit to the domestic hot water supply. The part is identified by the manufacturer's reference SATKF0046.
Signs this part needs replacing
- Domestic hot water running cooler than the setpoint despite correct HIU settings
- Reduced hot water flow rate through the unit
- Scale or debris build-up restricting the plate channels
- Visible weeping or staining at the plate pack or connections
- A growing temperature difference between primary flow and DHW outlet across the exchanger
Before you order
- Confirm the HIU model and that it takes the 30 plate 'long' variant
- Check whether the hot water or primary side exchanger is the one being replaced
- Inspect the existing plate pack and connections for scale or damage before ordering
