Pellet boiler Vitoligno 300-C, 2.4 to 12 kW

Vitoligno 300-C pellet boiler

The Vitoligno 300-C is a fully automatic pellet boiler with a broad spectrum of use ranging from low energy houses to buildings with larger heat demands.

It offers versatile and flexible supply system options for almost any application and stands out on account of its compact design which is ideal for limited room heights. In the output range from 2.4 to 48 kW, the pellet boiler modulates with a ratio of 1:3 and features impressively low energy consumption.

2015 | German Design Award WINNER

The German Design Award is presented by the German Design Council. 30 design experts from the areas of economics, academia and science judged a total of 1900 submitted entries and decided on the winners of the prestigious award.

Viessmann's Vitoligno 300-C boiler was named German Design Award WINNER 2015 in the "Excellent Product Design – Building and Energy" category.
 

Efficient and environmentally responsible

The Vitoligno 300-C has an efficiency of up to 95.3 percent when converting pellets into heat. Innovative combustion technology means the Vitoligno 300-C keeps dust values low and complies with the 1st BImSchV stage 2 [Germany]. Operating the Vitoligno 300-C is extremely easy, making heating with pellets highly convenient. Almost everything is automatic – from charging with pellets right through to cleaning.

Flexible fuel supply

Pellets are supplied to the Vitoligno 300-C either via a flexible screw conveyor or a vacuum system. Up to 12 kW, the boiler is equipped as standard with a vacuum system for automatic pellet discharge from the storage room. However, the versions with an output of 8 and 12 kW can also be converted from automatic to manual charging, quickly and easily. Commercially available bags of pellets can be used for manual charging, e.g. if there is insufficient space for a pellet storage room.

Compact dimensions

The pellet boiler (8 and 12 kW) allows flexible and space-efficient siting as all components are directly accessible for service and maintenance. Installation in a corner of the boiler room is ideal. Viessmann offers a complete range of accessories for pellet storage and transport from a single source.

Convenient automatic functions

Pellets burn with few residues – and even these are taken care of automatically by the Vitoligno 300-C. Fully automatic cleaning of the rotary finned grate in the combustion chamber happens at least once a day. This guarantees low losses and excellent fuel utilisation. Automatic ash removal compresses the ash in the ash box and ensures that it needs to be emptied no more than twice a year. Due to the fact that the ash box is sealed, ash removal is also clean and stress-free.

Intelligent Ecotronic control unit

Intelligent Ecotronic control unit

Operating the Vitoligno 300-C is easy with the weather-compensated digital Ecotronic control unit. It controls up to three heating circuits with mixer, two heating circuits with mixer and DHW heating, or one heating circuit with mixer, a solar circuit and DHW heating. An additional, fourth heating circuit with mixer can be connected via the KM-BUS. The boiler with pellet supply, the heating circuits and the cylinder temperature can all be controlled intuitively. Adjusting all relevant parameters is made easy by the clear display with graphic capability and multiple line plain text user prompts.

Prepared for solar

In combination with a solar thermal system, current solar data is shown directly on the display. The collector and cylinder temperature are included in this data, as are the operating hours of the solar thermal system.


Remote control and cascade controller

In combination with the Vitotrol 350-C (option), the boiler can also be controlled from the living space. With the 5-inch touchscreen in 16:9 format, operation could hardly be easier. The system can be extended to include up to 24 control loops using control modules. These can be used for heating circuits, DHW heating or in conjunction with a district heating supply line. The Vitotrol 350-C can also be used as a cascade controller for up to four wood boilers.

Vitoconnect 100 creates the connection

The Vitoconnect 100 interface is required to operate the pellet boiler by app.

ViCare App

ViCare App

The ViCare app allows the user to control their heating system via a smartphone. The operating status can be viewed at any time and, in the event of a fault, contact can be made quickly and easily with the installation company previously registered in the app.

Matching accessories

For pellet stores, modular 4 or 8-way wand changeover is available. Suction wands, evenly distributed in the pellet store, transport the pellets from the store to the pellet boiler. It is regulated by the Ecotronic boiler control unit and ensures an even discharge of pellets from the pellet store by changing the wands over automatically.

The routing of the wand system is flexible, making it suitable for various room formats (e.g. L-shaped, very elongated spaces or even split stores). As the sloping floor is no longer required, usable space is increased by up to 1/3 – this ensures optimum use of the pellet store.
