Viessmann Vitoplex 300 Low Combustion Chamber Steam Boiler

Viessman Vitoplex 300 has multi-layered convection heating surfaces with telescopic steel pipes for optimal heat transfer. It is a Three-pass boiler with integral start-up control. The designed of inner pipe with folded linear fins provides a heating surface 2.5 times larger than smooth pipes. Varied gaps between press points promote proportional heat transfer, reducing heat transfer to boiler water in triplex pipes’ back area.
