What it is
The Viessmann plate heat exchanger, part number 7827950, is a component used in Viessmann Vitodens 200-W combi boilers. It transfers heat between the boiler's primary circuit and the domestic hot water circuit. The plate design provides a large surface area for efficient heat transfer within a compact unit.
Signs this part needs replacing
- Domestic hot water runs lukewarm or does not reach the temperature set at the boiler.
- DHW temperature fluctuates during use.
- Reduced hot water flow rate at the taps.
- Water weeping or dripping from the plate pack.
- Primary pressure drops or DHW is discoloured due to an internal cross-leak.
Before you order
- Confirm the boiler model and serial number match one of the listed appliances.
- Verify the existing part number before ordering, as the plate heat exchanger is model-specific.
