The Baxi 5122147 Element Exchanger is a genuine replacement heat transfer component engineered to deliver efficient thermal performance in compatible Solo, Duo Tec and Megaflo boilers. This exchanger (often referred to as a heat exchanger element) is responsible for transferring heat from the combustion process into the central heating and hot water circuits. By providing a robust heat exchange surface, it helps maintain stable system temperatures, effective heat delivery and reliable hot-water response under everyday use. When the original heat exchanger element becomes worn, corroded or blocked, symptoms such as reduced performance, fluctuating temperatures or boiler fault codes can occur, so fitting the correct OEM part is essential for restoring dependable operation.

This element exchanger is compatible with Baxi Solo, Duo Tec and Megaflo series boilers that specify part number 5122147 in their technical documentation. To ensure correct fitment and reliable performance, always verify that the part number on your existing exchanger matches before installation, as heat exchanger designs and connections vary between models and outputs.

Supplied ready for direct replacement, the 5122147 Element Exchanger integrates with the boiler’s existing pipework and mounting points when installed by a qualified engineer. Choosing this genuine Baxi component helps restore efficient heat transfer, supports consistent system temperatures and contributes to dependable heating and hot-water performance in compatible Solo, Duo Tec and Megaflo boilers.
