Zero Flame Technology from ÖkoFEN

The cleanest ÖkoFEN pellet boilers ever, The particulate matter, popular with news outlets, from these boilers can hardly be measured according to tests carried out by TÜV Austria. 

Installing an ÖkoFEN pellet boiler requires careful planning and professional execution to ensure efficient and safe operation. Below is a step-by-step guide to the installation process:

Step 1: Assessment and Planning

Before installation, an assessment is carried out by a heating professional to determine:

• The heating requirements of the property (based on size, insulation, and climate).
• The best location for the boiler and pellet storage.
• The most suitable ÖkoFEN model based on heating demand.
• The type of heat distribution system (radiators, underfloor heating, or hot air).

Important Considerations:

• The boiler room must have adequate ventilation and space.
• The pellet storage area should be easily accessible for refilling.
• Existing chimneys may need modifications to accommodate pellet boiler flue systems.

Step 2: Preparing the Boiler Room and Pellet Storage

• The designated boiler room is cleared and prepared for installation.
• If required, a buffer tank (for storing hot water) is installed.
• A pellet storage system is set up, which could be:
  • Bag silo – a flexible, cost-effective solution.
  • Suction system with bulk storage – allows pellets to be transported from a separate storage room.
  • Integrated hopper – for compact installations.

Step 3: Installing the ÖkoFEN Boiler

• The ÖkoFEN pellet boiler is placed in the boiler room.
• It is connected to the heating circuit and domestic hot water system.
• Flue gas exhaust and fresh air intake are installed. Depending on the boiler type, this could involve a condensing unit for extra efficiency.
• Electrical connections for the boiler control system and automation are established.
• The pellet transport system (suction system or auger) is connected between the storage and boiler.

Step 4: System Testing and Commissioning

• A professional technician configures the boiler settings based on the property’s heat demand.
• The system is tested for leaks, pressure, and proper function.
• The control panel is programmed for automated operation and efficiency optimization.
• The first batch of pellets is loaded, and the boiler is ignited.
• The technician provides user training on operation, maintenance, and remote monitoring (via smart control apps).

Step 5: Maintenance and Ongoing Use

• Regular maintenance includes cleaning the heat exchanger and emptying the ash container (which is minimal due to high efficiency).
• Annual servicing by a certified technician ensures long-term reliability and peak performance.
• The system can be monitored via the ÖkoFEN app, allowing for adjustments and real-time diagnostics.

Benefits of Using Pellets for Heating

Switching to wood pellets as a fuel source provides numerous advantages for both residential and commercial heating. Here’s a detailed breakdown of the key benefits:

1. Renewable and Sustainable Energy Source

• Wood pellets are made from compressed sawdust and wood shavings, which are byproducts of the timber industry.
• Unlike fossil fuels, wood pellets are carbon-neutral because the CO₂ released during combustion is offset by tree growth.
• Sustainable forestry practices ensure continuous availability of pellet fuel.

2. Cost-Effective Heating Solution

• Lower fuel costs: Wood pellets are typically cheaper than heating oil, propane, or electricity.
• Stable prices: Unlike fossil fuels, pellet prices are less volatile because they are not tied to global oil and gas markets.
• High energy efficiency: Modern pellet boilers achieve 90–107% efficiency, meaning less fuel is needed to produce the same amount of heat.

3. Automated and Convenient Operation

• Self-feeding system: ÖkoFEN pellet boilers automatically transport pellets from the storage unit to the combustion chamber.
• Self-cleaning function: Reduces the need for frequent manual maintenance.
• Smart controls: Users can monitor and adjust settings remotely via a smartphone or tablet.

4. Clean and Low-Emission Heating

• Low particulate emissions: ÖkoFEN’s ZeroFlame technology minimises fine dust, making it one of the cleanestheating solutions available.
• No smoke or odour: Unlike burning firewood, pellet combustion is clean, producing very little ash.
• Meets strict environmental regulations: Many ÖkoFEN models comply with future EU emission standards.

5. Energy Independence and Security

• Homeowners and businesses using pellets are less dependent on fossil fuel imports.
• Pellets can be sourced locally, reducing reliance on international energy markets.
• With an electricity-generating ÖkoFEN boiler, users can even produce their own heat and power, increasing self-sufficiency.

6. Space-Saving and Flexible Storage Options

• Unlike firewood, pellets take up less space and can be stored in compact silos or bags.
• Bulk delivery options allow for easy refilling, just like oil or gas tanks.
• ÖkoFEN offers flexible storage solutions, including underground silos, fabric bag silos, and small hopper systems.

7. Long-Term Durability and Reliability

• ÖkoFEN pellet boilers are built to last, with a lifespan of 20+ years when properly maintained.
• High-quality Austrian engineering ensures reliability and efficiency in all weather conditions.
• Minimal moving parts reduce wear and tear, lowering maintenance costs.
