OIL/GAS CONDENSING BOILERS VITORADIAL 300-T Efficient heating operation with condensing technology and the proven Inox-Radial heat exchanger

Condensing technology with the proven Inox-Radial heat exchanger for efficient heating operation The Vitoradial 300-T condensing boiler is particularly compact. It is supplied as a unit with a downstream flue gas/water heat exchanger and the Vitoflame 100 pressure-jet burner (up to 335 kW). High efficiency with two-stage heat recovery The Vitoradial 300-T is an innovative combination of the Vitoplex 300 low temperature boiler with an Inox-Radial heat exchanger directly attached to it for utilising condensing technology. The proven multi layered convection heating surfaces combined with the...

Its compact design and low build height make the Vitoradial 300-T the ideal choice for modernisation projects. Triplex pipes for 2.5 times larger heating surface The multi layered convection heating surfaces of the Vitoradial 300-T comprise telescopic steel pipes pressed together for heat transfer. The inner pipe, with its folded linear fins, creates a heating surface 2.5 times greater than that of smooth pipes. Heat is transferred through the different gaps between the press points in such a way that the back area of the triplex pipes transfers less heat to the boiler water, as the...

VITOPLEX 300/200 VITOROND 200 Proven Viessmann quality up to 2000 kW for oil and gas with high standard seasonal efficiency [to DIN]

Innovative heating technology -the right solution for every need The comprehensive range from Viessmann covers every demand for innovative heating technology. Every user can find the right solution here: with regard to building services, convenience and budgetary constraints. In terms of technology and price, the Vitoplex range is divided into the 300 and 200 categories. One thing that all products have in common is the top quality for which Viessmann is renowned. The Vitorond 200 comes into its own where the boiler needs to be installed under demanding spatial conditions. VITOPLEX 300 Low...

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 The multi layered convection heating surfaces of the Vitoplex 300 comprise telescopic steel pipes pressed together for heat transfer. The inner pipe, with its folded linear fins, creates a heating surface 2.5 times greater than that of smooth pipes. Heat is transferred through the different gaps between the press points in such a way that the back area of the triplex pipes transfers less heat to...

Convenient and highly capable Vitotronic control unit The integral Vitotronic control unit, with its large colour touchscreen, is simple and intuitive to use. An assistant function helps with commissioning. The boiler can be connected directly to Vitodata via a Vitocom interface. This option provides heating contractors with additional digital services to ensure fault-free system operation. The Vitosoft 300 service tool communicates directly via WiFi. Energy consumption can be clearly visualised on the control unit's energy cockpit. Hot gas flue (third pass; multi layered convection heating...

LOW TEMPERATURE OIL/GAS BOILERS The compact Vitoplex 200 steel boiler is available from 440 to 1950 kW. Over its entire output range, this three-pass boiler offers the right conditions for environmentally responsible and clean combustion. A wide range of burners can be adapted for use with this boiler. The low combustion chamber loading produces especially low nitrogen oxide emissions. A neat fit even when space is tight The Vitoplex 200 is easy to manoeuvre. It saves space and the walk-on boiler cover (from 700 kW) facilitates installation and maintenance. Finely adjusted pressure-jet...
