Vitoplex 300 low temperature oil/gas boiler

Three-pass boiler with integral start-up control

The Vitoplex 300 three-pass boiler, with its proven multi layered convection heating surfaces, offers particularly economical, clean and reliable operation.

Multi layered convection heating surfaces made from triplex pipes

The multi layered convection heating surfaces of the Vitoplex 300 are comprised of telescopically arranged steel pipes pressed into each other for ideal heat transfer. The inner pipe, with its folded linear fins, creates a heating surface 2.5 times greater than that of smooth pipes.

Heat transfer occurs proportionately due to the different gaps between the press points, so the back area of the triplex pipes transfers less heat to the boiler water, as the combustion gases circulating here are no longer quite as hot. This way, the surface temperature remains above the dew point, the formation of condensate is counteracted and corrosion damage is prevented.

Convenient and highly capable Vitotronic control unit

The user friendly Vitotronic control unit with a large colour touchscreen enables quick commissioning using the assistant function. The boiler can be connected directly to the internet for remote monitoring via the integral LAN interface. The Vitosoft 300 service tool communicates directly via WiFi. Energy consumption can be clearly visualised on the control unit's energy cockpit.
