Heatingwith a clear conscience

Expertise, innovation and qualityunite in our company. We create our future together with our em-ployees by incorporating this philosophy.Founder and Managing Director Herbert Ortner

OkoFEN - the visionOur primary objectives are the research, development and production of small scale ecological biomass heating systems. This mission is reflected in our company name OkoFEN (Eco Research & Development).

We are a family business and together with our col-leagues and partners, we reflect our values throughout the whole of our business. Ecology is at the core of all our activities forming the basis of our company philosophy.

OkoFEN was the first Austrian manufacturer to offer an officially certified pellet heating system to the public, a year after the introduction of wood pellet fuel to the Austrian market.

This pioneering activity influenced the heating industry and heralded a period of extraordinary market develop-ment.

In 2004 we launched a pellet heating system with con-densing technology, a world first. This development drew international acknowledgement and praise from the heating industry.

These and many other innovations have made us what we are: Europe’s specialist in pellet heating.

Philosophy

Pioneering spirit Pioneers in our field, we were the first to develope a fully automatic wood pellet boiler system, confirming OkoFEN as the technological leader in Europe.

Ecology The use of locally sourced, CO2 neutral, wood fuel is one of the fundamentals of our environmental conviction. We also apply our ecological ethos to other areas of our environment, for example; power is 100% green electricity; buildings are designed to low energy principles; packaging is eco-friendly; and transportation is kept to a minimum.

Partnership and Responsibility This is the basis of how we communicate with each other, our partners, our customers and end users. Our undisputed reputation and high customer satisfaction is achieved by means of a sophisticated, advanced product and dedicated, competent staff.

QualityExcellence in research, development, design, production, finish and after care are key to the quality of Okofen products and are recognised by many national and interna-tional awards. We are motivated and committed to continue our product development and new ventures by the confidence of our clients and the needs of the future.

Wood Pellets

Energy now and for the futureRecycled post-industrial waste as fuel? That’ll be the wood pellet. Manufactured from clean dry wood waste, such as wood shavings and sawdust, the pellets are formed at very high pressures where nearly all moisture is extracted and the natural resins present in the wood (lignin) form a glossy coating. For a solid fuel the pel-lets are very small (3/16 - 4/16 Inch diameter, 3/8 - 1 5/8 Inch long) and are nearly as fluid as traditional liquid/gas fuels. One cubic foot of pellets weighs >40 lb.

Clean and easy deliveryAutomatic pellet deliveries are blown from the pellet tanker to your FleXILO using a flexible hose. Pellets are without scent, unlike liquid fuels, and do not release any traces of oil.

Sustainable SupplyThere are now wood pellet production plants across the whole of Europe and North America, providing a long term, sustainable supply. Wood pellet fuel is set to be-come the heating fuel of the future.

Independence from unstable regionsWood pellets are manufactured and distributed region-ally, and are not, as is the case with fossil fuels, subject to regional instability, such as in the Middle East.

Support for regional economyThe production of wood pellets provides added value to a waste product, which can directly benefit local econo-mies with the creation of secure local employment.

Quality is vitalTo have an efficient and environmentally safe operational heating system the guaranteed quality of the fuel plays an important role. Only use wood pellets which meet the US/CAN certified standards.

Wood Energy8

Forever available - now and in the futureTrees are the raw material that wood pellets are made from, with conifers providing the best quality waste for pellets. Unlike oil and gas, which are predominantly finite imported resources, trees are a renewable resource avail-able regionally throughout North America. The possibilitiy to combine wood pellets and solar also offers the option of free and unlimited renewable energy use, enabling further energy savings.

CO2 reductions in the right placeSpace heating and hot water account for around 89 percent of energy consumed in an average household, making it by far the largest part of the energy costs for consumers. We are in the middle of an energy revolution. Cost esca-lations and supply shortfalls in the fossil fuel market are the result. We must begin today with forward-looking measures. Renewable energies, such as solar and wood pellet fuel, are the future and make us independent. It is time to change!

Household energy consumptioin

Heating 77%

Hot water 12%

Household appliances 6%

Lighting 2%

Cooking 3%

CO2 balance

As trees grow they absorb carbon dioxide from the air, the amount of carbon dioxide that a tree fixes during its life is released again in the same quan-tity whether the timber is burnt or decomposes. The CO2 emission from combustion is no higher than the emission for natural decomposition.Relax in the knowledge that our eco-friendly equipment contributes to a more balanced envi-ronment.

FleXILO storageThe pellets are delivered by pellet tanker and blown into the textile FleXILO. The pellet tanker has up to 96 ft of delivery hoses, therefore the FleXILO must be within 96 ft of the tanker access. The tank room should have an outside wall, so that the fillers are accessible from outdoors, where possible. The boiler room air supply must comply with current building regulations.

Room dimensionsLayout: The tank installation room must be at least 4 in (0.33 ft) wider than the tank itself. For example: s190H – tank width 6.46 ft minimum room width = 6.79 ft

For installation reasons, on the side of the tank where the filler coupling is fitted, the room must be 11 7/8 in longer than the minimum stated. For example: s190H – minimum room length: 6.46 + 1 = 7.46 ft

Height of the room:The minimum required height of the room is 5.9 ft/7.1 ft. see installation examples!

Connection to the heating system: The boiler has its own wire centre. It requires a 6 Amp / 14 Amp power supply.

External emergency stop switch: Outside the boiler room, and near the boiler room door, we recommend an “emergency stop switch“.
