The Alpha 1.022221 Domestic Hot Water (DHW) Heat Exchanger is a genuine replacement component designed to restore efficient hot water performance in the Alpha CD28 boiler. This plate heat exchanger transfers heat from the primary circuit to the domestic hot water supply, ensuring strong flow rates and consistent temperature.

Over time, heat exchangers can become restricted by scale, debris, or sludge, leading to temperature fluctuations, reduced flow, or poor hot water output. Replacing it with this genuine Alpha unit restores full efficiency and reliable hot water delivery.
