The very neat metal casing with a perfect finish brings a remarkable design to this boiler equipped with a reliable and very advanced technology allowing to obtain efficiencies superior to 95% also thanks to very important exchange surfaces.
The 100% automatic cleaning of the turbulators, the combustion chamber and the burner allows heating in peace without any manual intervention.
The ashes are compacted and directed with the help of an endless screw towards a large capacity external ashtray, limiting cleaning interventions as much as possible.
Practical, automatic and economical, the ORUS Prestige boiler will be able to supply the central heating circuit as well as the domestic hot water if necessary while being managed automatically by its class V control software also allowing the power to be modulated from 20 to 100%.
The choice of noble and resistant materials and the addition of reliable electrotechnical components allow efficient operation and a long service life.
