What it is
The Viessmann Plate Heat Exchanger 18 Plates (part number 7841779) is a plate-type heat exchanger used in Viessmann Vitodens 050-W combi gas boilers. It transfers heat between the primary circuit and the domestic hot water circuit within the appliance. The 18-plate stack provides the surface area required to heat domestic water on demand.
Signs this part needs replacing
- Domestic hot water running hot and cold or losing temperature during draw-off
- Reduced hot water flow rate compared with the cold supply
- Heat exchanger blocked or scaled, with poor heat transfer to the domestic water
- Water weeping from the plate pack or its seals
- DHW temperature no longer matching the boiler setting
Before you order
- Confirm the boiler model and serial number against the fit list above
- Check the existing heat exchanger plate count and part number
- Inspect the seals and connections for scale or debris before fitting
- Verify the fault is not caused by a diverter valve or sensor issue
