Viessmann biomass boilers: efficient systems for environmentally-friendly heat generation with wood

This year, Viessmann will offer the following performance

enhancements for efficient, environmentally friendly heating with

wood:

- The output range of the fully automatic pellet boiler

Vitoligno 300-C is being extended up to 48 kW. The boiler

fulfills all requirements of the second stage of the 1st

German Federal Emission Control Act (1. BImSchV).

- The fully automatic biomass boiler Vitoligno 300-H for

woodchips and wood pellets is available from this spring

with additional rated heat outputs of 50 and 60 kW. When it

is operated with wood pellets, the emissions limits will be

adhered to which were introduced on January 1st, 2015, in

the second stage of the 1st German Federal Emission

Control Act.

Vitoligno 300-C: fully automatic compact pellet boiler with additional output capacities

Vitoligno 300-C is a compact pellet boiler which particularly

impresses due to its convenient operation and degree of efficiency

of up to 95 percent. The boiler received the prestigious Vorarlberg

innovation award last year because of its low emission combustion

and this year the German Design Award for its design. It is now

available with five further output capacities up to 48 kW.

Fully automatic operationWith output capacities of 18 to 48 kW, the pellet boiler can be

charged either via the integrated suction system or a flexible

auger. With the suction system, the turbine integrated into the

boiler draws the wood pellets directly out of the pellet store or

pellet silo. With the flexible auger, the boiler is supplied with fuel

via a screw conveyor system. Automatic ignition (glow igniter) is

carried out by a power-saving ceramic heating element. The

stainless steel finned grate and all surfaces of the Vitoligno 300-C

in contact with ashes are cleaned automatically.

Convenient removal of ashesThe ashes are conveyed via the automatic removal procedure to

the ash bin trolley and are condensed at the same time. The

mobile ash bin trolley has a capacity of up to 40 liters, making it

much bigger than those of other pellet boilers. It needs emptying

only once or twice a year. The closed trolley means that disposal is

dust-free and very easy.

Convenient operationRegulation of the boiler is as convenient as its operation. The

weather-compensated Ecotronic controller has a graphic display

with several lines of text and is programmable. Up to three heating

circuits plus DHW generation and a solar circuit can be controlled

in the standard design. A fourth heating circuit can be connected

via the KM bus system. The controls are all menu-guided. Offered

as an accessory, the wireless remote control Vitotrol 350 with

touch display enables users to obtain all information and use all

functions while in the living space.

Economical and environmentally friendly wood combustionThe innovative combustion technology ensures low fuel

consumption and low emissions with its stratified fire bed,

overhead charging of the combustion chamber, and output

modulations of 1:3. The Vitoligno 300-C pellet boiler thus fulfills the

strict emissions limits that have been in force since January 1st,

2015, in the second stage of the 1st German Federal Emission

Control Act (BImSchV). Additional secondary measures such a

fine dust filters are not required.

Coordinated accessoriesA pellet hopper suitable for low-ceilinged rooms is also available

for the suction system. It can be set up directly next to the boiler

and filled, for example, with pellets from bags.

The annual requirement for pellets is usually stored in suitably

large pellet storage facilities. A modular 4/8 times suction probe

system is also available. It is controlled via the boiler control unit

and ensures that pellets are taken from the storage facility with an

even distribution. For this purpose, there is automatic switching

between the probes, according to how the pellets are distributed.

The new probe system also has the security function of "wind

back". If the pellet tubes are blocked, the suction direction of the

turbine is reversed and the tubes are automatically blown free. The

probes can be flexibly laid and are suited to very different

environments. They can be used in walled storage facilities with

and without a sloping floor, for up to two separate loading zones,

and storage facilities with unhelpful shapes (e.g. very elongated or

L-shaped spaces).

Advantages for market partners- Easy installation thanks to compact design with suction

system (integrated suction turbine) or flexible auger

- Pellet hopper for low-ceilinged rooms (18 to 24 kW: <

1,400 mm, 32 to 48 kW: 1,600 mm)

- Rapid start-up procedure thanks to Ecotronic controls with

start-up assistant

- Software update-function per SD card

- Coordinated accessories for pellet feed and storage

- Clean, efficient combustion thanks to low dust emissions,

adherence to 1st German Federal Emission Control Act,

Stage 2

Advantages for owners- Fully automatic pellet boiler for convenient heating with

wood

- Low fuel consumption due to high degree of efficiency,

modulating mode, and weather-compensated control unit

- High operational reliability thanks to self-cleaning stainless

steel finned grate and rotary airlock feeder for full anti-burn-

back protection

- Low power consumption thanks to automatic ignition with

ceramic heat element

- Automatic ash removal, ash bin trolley only needs emptying

once or twice a year

Technical specifications- Heat outputs of 2.4 to 48 kW

- Degree of efficiency up to 95.3 %

- Modulation range 1:3

- Volume of ash bin trolley up to 40 l

AvailabilityVitoligno 300-C's new output capacities of 18 to 48 kW are

available from August 2015.

Vitoligno 300-H: biomass boiler with additional output capacities for smaller heating loads

The biomass boiler Vitoligno 300-H can be fed either woodchips or

pellets. This means that the owners can choose between the two

fuels as they wish. Numerous functions allow for convenient, fully

automatic heat generation. Two new, smaller output capacities of

50 and 60 kW of rated heat output now extend the utilization

possibilities of the boiler.

Automatic functions for greater comfortThe numerous automatic functions include an automatic fuel feed,

automatic ignition, ash removal from the dual rotary grate when

required, and cleaning of the heat exchanger. The ash is

mechanically conveyed into the large mobile ash bin trolley.

Emissions below limits of the 2nd Stage of the 1st German Federal Emission Control Act (BImSchV)With its weather-compensated controls and a wide modulation

range of 1:3, the boiler adjusts its output precisely to the current

heat demand and achieves a high degree of efficiency of 95 %. Its

staged combustion with a primary and secondary air feed ensures

low emissions. Vitoligno 300-H burns woodchips with a water

content of up to 30 percent. When burning pellets in accordance

with the standard ENplus-A1, the boiler meets the requirements of

the second Stage of the 1st German Federal Immission Control

Act.

Ecotronic control unit The Ecotronic control unit with integrated start-up assistant,

illuminated display, and text display controls

- up to four heating circuits with mixer (fourth heating circuit

is connected via KM bus module) or

- two heating circuits with mixer and DHW generation or

- a heating circuit with mixer, a solar circuit and DHW

generation.

Up to 24 heating circuits are possible in connection with the

remote control Vitotrol 350 (optional). Operation is easy thanks to

the well set out menu structure. The graphics-capable and easy-to-

read touch display with several lines of text makes it easy to set all

the relevant data.

Fuel feed Fuel feed is carried out on the rear side of the new Vitoligno 300-H

with 50 and 60 kW output, in contrast to boilers with high output

capacities (80 and 100 kW). The boiler can therefore be placed

with the right side to the wall to save space.

Simple transport and coordinated accessoriesCompact dimensions make it easier to transport and install.

Accessories such as storage and feed systems for pellets and

woodchips make installation simpler. All components are precisely

matched to one another and guarantee smooth working.
