Échangeur de chaleur pour eau chaude sanitaire (12) à plaques De Dietrich 721987900

A DHW heat exchanger with 12 plates is designed to transfer heat from the primary heating circuit to domestic hot water on demand. This plate heat exchanger ensures rapid and efficient hot water production for taps and showers. If your boiler is struggling to deliver consistent hot water or showing error codes related to DHW, a faulty heat exchanger may be the cause. Replacing it with a 12-plate unit can restore hot water performance and improve overall system efficiency.
