What it is
The Vaillant 0020127204 is a plate to plate heat exchanger used in Vaillant heat pump appliances. It transfers heat between two separate water circuits across a stack of corrugated plates, keeping the circuits sealed from one another. It is fitted to the VWL 45/1 A 230V range.
Signs this part needs replacing
- Domestic hot water temperature that fluctuates or fails to reach setpoint
- Reduced flow rate or increased pressure drop across the heat exchanger
- Visible water or scale deposits around the plate pack or connections
- Cross-contamination between the primary and secondary circuits
- Repeated scale-related blockages after flushing
Before you order
- Confirm the appliance model matches one of the fit lines above
- Check the part number on the existing component against 0020127204
- Inspect the connections and mounting points for damage before fitting
- Verify the fault is with the heat exchanger and not the pump, diverter or controls
