The Worcester 87154069500 Heat Exchanger is a genuine replacement component engineered to transfer thermal energy from the combustion process into your boiler’s central heating and domestic hot-water circuits efficiently and reliably. As the key heat transfer element, this exchanger captures heat produced by the burner and passes it into the boiler’s water system, helping maintain stable temperatures, responsive hot-water delivery and consistent central heating performance. Over time, heat exchangers can become blocked, corroded or less efficient, which may lead to reduced heat output, fluctuating temperatures or boiler fault codes, so fitting the correct OEM heat exchanger is essential for restoring dependable operation.

This heat exchanger is compatible with specific Worcester and Worcester Bosch boilers that reference part number 87154069500 in their technical documentation. To ensure correct fitment and performance, always verify that the part number on your existing heat exchanger matches before installation, as designs, connection sizes and plate configurations vary between models and system types.

Supplied ready for direct replacement, the 87154069500 Heat Exchanger integrates seamlessly with the boiler’s existing pipework connections and mounting points when installed by a qualified engineer. Choosing this genuine Worcester Bosch component helps restore efficient heat transfer, supports consistent system temperatures and contributes to reliable central heating and hot-water performance in compatible boiler systems.
