What it is
The Vokera 20157769 is a domestic hot water (DHW) heat exchanger used in Vokera combi boilers. It transfers heat from the primary heating circuit to the domestic hot water supply so the appliance can deliver hot water on demand. It is fitted across the Vision Plus and Easi-Heat Plus ranges, along with the Compact 32A DIN ERP.
Signs this part needs replacing
- Domestic hot water runs lukewarm or does not reach the set temperature
- Hot water temperature fluctuates during draw-off
- Reduced hot water flow rate at the taps
- Water weeping from the heat exchanger body or its connections
- Scale or debris restricting flow through the plate, common in hard water areas
Before you order
- Confirm your boiler model against the fit list above
- Check the part number 20157769 against the component currently fitted or the manufacturer's parts list
- Confirm the fault lies with the heat exchanger rather than another DHW component
- Consider a system flush or scale treatment if the existing part is blocked
