The Alpha 3.022784 18-Plate Heat Exchanger is a genuine replacement domestic hot water (DHW) plate heat exchanger designed to efficiently transfer heat between the primary circuit and hot water supply in compatible Alpha boilers. Over time, heat exchangers can become restricted by scale, sludge, or debris, leading to reduced hot water temperatures, poor flow rates, or fluctuating performance.

This high-quality 18-plate unit restores efficient heat transfer, consistent hot water delivery, and overall system reliability.
