The Viessmann 7841770 plate heat exchanger is a genuine replacement part designed to transfer heat between the primary heating circuit and domestic hot water system in compatible Viessmann boilers. Over time, plate heat exchangers can become restricted by limescale, sludge, or internal blockage, leading to reduced hot water flow, temperature fluctuations, or boiler inefficiency.
Replacing a worn unit with the 7841770 restores proper thermal efficiency and ensures consistent hot water delivery. It is manufactured to Viessmann’s original specifications, ensuring correct fitment, high-pressure durability, and long-term reliability in everyday operation. This part is commonly used in Vitodens 050-W combi boiler models.

- Genuine Viessmann OEM replacement part
- 14-plate heat exchanger for efficient thermal transfer
- Restores domestic hot water performance and flow rate
- Helps eliminate issues caused by limescale and blockage
