Ferroli, the European manufacturer of cast-iron boilers has the pleasure to give you the right answer with its new series, the GN series. The GN Series has two boiler types; the GNI boiler has an open Spatio burner, and the GN Unit has an enclosed Spatio burner for quieter operation.

In order to best maintain the thermal performances of the boiler, the GN boiler has been thoroughly insulated in a 60 mm thick glass wool layer. The insulation significantly reduces the waste heat in the boiler room.
