The Baxi 720776401 PT-to-PT Heat Exchanger is a genuine 14-plate domestic hot water (DHW) heat exchanger designed for use in selected 24kW and 28kW Baxi boilers. This component transfers heat efficiently from the primary circuit to the hot water supply, ensuring fast, stable, and reliable hot water performance.

Over time, plate heat exchangers can become restricted due to limescale or debris, leading to poor hot water flow, fluctuating temperatures, or delayed ignition. Replacing it with this genuine Baxi part restores full DHW efficiency and consistent hot water delivery.
