The Alpha InTec range of high efficiency condensing boilers are wall mounted, fan assisted room-sealed combination boilers.
The burner is lit electronically and the heat output is controlled by a modulating fan and gas valve. These are combination boilers providing both central heating and domestic hot water at mains pressure.
The boilers are supplied with a pump, pressure relief valve, expansion vessel and pressure gauge fully assembled and tested. They are designed for use with a fully pumped, sealed and pressurised central heating system.
GS models have an energy saving device (GasSaver), listed in the Government's SAP Appendix Q as a passive flue gas heat recovery device (PFGHRD) fitted within the boiler casing.
The GasSaver recycles heat recovered from the flue exhaust gases which is used to pre-heat the incoming cold mains water supply before entering the boiler, thereby reducing gas consumption and improving domestic hot water efficiency.
