Alpha Combi Boilers

CDX boilers are built to the same high standards found in all our boilers, using stainless steel and top quality components. This enables them to attain the same exceptional levels of performance and reliability achieved in products across the Alpha range.They are SEDBUK Band 'A' rated, and are recommended by the Energy Saving Trust.

The Alpha CD50 wall-hung high efficiency storage combi matches a traditional system's higher flow rate whilst also offering the benefit of hot water on demand whenever you want it. Its compact 'all-in-one' design gives installers the best of both worlds.

Next Generation boilers are all SEDBUK Band A rated, with a fully modulating low NOx burner and are available in 25, 28 and 35kW output models. The boilers also feature an Alpha-designed Hydroblock that reduces pipework and minimises noise.

To maximise performance, the built-in seasonality valve automatically adjusts the DHW flow based on the temperature of the incoming main. This allows more flow in spring, summer and autumn.
