DESCRIPTION
The Alpha Range of boilers are wall mounted, fan assisted room-sealed combination boilers, providing both central heating and
domestic hot water at mains pressure.
The Alpha 240E and 240P boilers are suitable for central heating loads of between 9.3 and 23.3 kW (31 700 and 79 500 Btu/h). The
Alpha 280E and 280P boilers are suitable for central heating loads of between 9.3 and 28 kW (31 700 and 95 500 Btu/h).
The boilers will provide central heating (as required) during the 'on' times set on your clock (if fitted). Hot water is always
available whenever a hot tap is opened and takes priority over the central heating.
Note: The Alpha 240P and 280P use a permanent pilot for lighting the burner, and the Alpha 240E and 280E burner is lit
electronically.
