The Worcester Bosch 87161429030 CDi Plate Heat Exchanger PVW 14E is a genuine replacement component engineered to restore efficient hot-water performance within your boiler. As a plate-type exchanger, it uses multiple stainless-steel plates to transfer heat rapidly from the primary heating circuit to the domestic hot-water supply, helping maintain stable temperatures, fast heat-up times and reliable delivery during everyday use. A worn or blocked plate heat exchanger can cause fluctuating temperatures, reduced hot-water flow and boiler lockouts, making timely replacement essential.

This PVW 14E plate heat exchanger is designed for use in select Worcester Bosch 28CDi boilers, including versions of the 28CDi RSF in both natural gas and LPG formats that reference this part number. To ensure correct compatibility, always match the number on your existing heat exchanger or check against the boiler’s data label before installation.

The 87161429030 heat exchanger fits directly in place of the original using existing pipework connections and mounting points, allowing straightforward replacement by a qualified engineer. Installing this genuine Worcester Bosch component restores effective heat transfer, protects the boiler from unnecessary strain and ensures consistent hot-water output in compatible CDi appliances.
