The Alpha CD18S, 24S and 30S are high efficiency condensing, wall mounted, fan assisted, room-sealed system boilers. The
burner is lit electronically and the heat output is controlled by a modulating fan and gas valve.
These are system boilers providing heating only for sealed central heating systems.
The boiler is supplied with a pump, pressure relief valve, expansion vessel and pressure gauge fully assembled and tested.
The boiler provides central heating, and is designed for use with a fully pumped, sealed and pressurised central heating
system using only Natural gas.
The CD18S boiler is suitable for central heating loads of between 4.7 and 19.5 kW (16 050 and 66 500 Btu/h).
The CD24S boiler is suitable for central heating loads of between 4.7 and 25.4 kW (16 050 and 86 700 Btu/h).
The CD30S boiler is suitable for central heating loads of between 6.5 and 29.8 kW (22 200 and 101 700 Btu/h).
