In Alpha CD50 boiler is combi boiler with a built-in water store allowing the unit to deliver higher hot water demands than a standard combi boiler, but without the need to have a hot water in an attic space like a conventional boiler would require.

Built-in 52 litre storage cylinder allows the boiler to be used in homes where water demands are high, and can cope with situations such as filling a bath and having a shower at the same time. The water store can fill a bath in 3 to 5 minutes and the powerful heat exchanger can recover the store in just 3 minutes.
