A CO2-neutral Fuel for a sustainable Future
Wood fuel has been used by humans for thousands of years. It is clean
cheap and non polluting, the ultimate environmental friendly fuel. Wood
fuel is CO2 neutral: CO2 released through combustion is captured by the
growth of next years forests. Our boilers tap into this cycle of nature,
warming your home with out harming the environment.
All your Requests ...
will perhaps not be fulfilled by us. However, we help you to feel
comfortable at home.
The visioncomfort EKA pellet stove with water jacket (= central
heating boiler) embodies a perfect combination of modern design,
sensual romance and comfortable heating technology.
Efficient central heating in a low energy house or elegant additional
heating – visioncomfort EKA is always a visual pleasure and an eye
catcher in any living room. A vision was born
Our Promise
The sustainable exploitation of natural resources demands responsibility,
heart and creativity. Our specialists have a decade of experience and
research expertise. This contribution to a livable energy future is a
promise to our customers and the next generations: We are doing
everything to ensure further development of non-polluting heating
systems and the generation of new ideas. This is one of the reasons why
we were honoured with the „ENERGY GENIUS“ innovation award by the
Austrian Federal Ministry for Environment.
Fuel from the Region
Wood fuel is plentiful in Europe and usually available from local
source providing security even in times of an energy crises.
Locally produced fuel boosts the local economy, and short
transport routes reduces road trafic and pollution.
High-quality pellets (certified according to ÖNORM M 7135 and
DINplus) are important for an efficient combustion. Regional
forest enterprises, pelletising factories and retailers take care
that the availability will cover the whole country.

Low-E and stable Ignition
The pellets are ignited using an
electric ceramic heating element
(see picture). Air is heated by being
blown over the element and onto
the pellets in the combustion

chamber which ignite within a
couple of minutes. The system is
simple, reliable and has a low power
consumption.
Patented Grate Cleaning
The quiet stainless steel comb grate
ensures a regular, automatic deslagging
and ash removal as well as permanent
week-long operation and at the same time
Tilting Grate provides for highest operating efficiency
and ideal comfort. Due to the conical
burnout funnel, unburnt parts slide again
into the hot combustion chamber – giving
low ash development and consistent high
efficiency.

Efficient Heat with a Breeze of Romance
Only about 15 % of the heat is released by radiation throughout the window in the front door directly into the
dwelling. That means, your living room will never get too hot, but will always be well temperated – Efficiency
combined with the romantic magic of fire!
Intelligent Device Control visioncontrol
It is important to dimension the boiler correctly, i.e. the boiler must be
chosen according to the calculated heat requirement. During operation,
the intelligent, capacity-modulating control unit ensures fine
adjustment. In combination with an exterior temperature control,
a maximum heating comfort and an ideal operating efficiency will be
achieved. Boiler capacity and combustion performance adapt in a
modulating way to the current heat requirement. Higher comfort and
higher operating efficiency thanks to more intelligence!

Flexible Pellet Conveying System visionconvey AIR
The new visionconvey AIR suction conveying system provides a number of various application and combination
options for a comfortable automatic operation (see below). The flexible hose line (up to 15 meters horizontal and
5 meters vertical transport distance) permits a gentle pellet transport either from a basement storage room, from
a fabric tank or from an external terrestrial tank into the integrated hopper (capacity of about 50 liters) of the
boiler. A short insertion screw conveys the pellets to the standard air-lock, where fuel is dosed in a performance-
related way. Then pellets fall into the combustion chamber via a discharge chute. It is of course possible to
retrofit the automatic visionconvey AIR suction system.

Individual Choice of the Room used for Pellet-Storage
Most pellets storage rooms are situated in the
basement. However, it is also possible to store the fuel
on other levels of the house. Ideally, the storage room
is a room with an external wall in order to ensure an
easy filling by means of two STORZ couplers. A tilted
bottom (with about 35-45° inclination) supports the
slipping of the fuel. Please comply with the technical
documentation and with the effective fire protection
regulations (e.g. TRVB H118).
The flexible visionconvey AIR pellet suction conveying
system allows for various storage options, satisfying
individual needs.
Integrated Pellet Hopper (Intermediate Hopper)
As with a log basket beside a traditional fireplace containing a
days worth of fuel, the visioncomfort EKA utilizes of an integrated
pellet hopper with a capacity of about 50 liters (= 35 kg pellets).
The hopper may be filled manually or may be combined with the
automatic visionconvey AIR pellet conveying system.
The visionconvey AIR system will automatically fill he hopper
as and when required.
