What it is
The SATKF2006 is a 22 plate domestic circuit plate heat exchanger rated at 50kW, manufactured for Caleffi HIU appliances. It transfers heat from the primary circuit to the domestic hot water circuit within the heat interface unit. The plate pack provides the surface area needed to meet the domestic hot water demand at the rated output.
Signs this part needs replacing
- Domestic hot water running cooler than the setpoint despite correct primary flow temperature
- Unstable or fluctuating hot water temperature at the tap
- Reduced hot water flow rate through the unit
- Scale or debris build-up restricting the plate channels
- Weeping or leakage from the plate pack or its connections
Before you order
- Confirm the appliance model against the manufacturer's parts list
- Check the plate count and kW rating match the unit being replaced
- Rule out primary circuit faults, sensor faults and control settings before replacing the heat exchanger
- Inspect the connections and mounting arrangement on the existing unit
