Pellergy LLC has been importing and installing the Winhager BioWIN wood pellet boilers since 2013,  with a proven track record in reliability and performance. The Windhager BioWIN2 Series of wood pellet boilers are one of the most advanced, efficient, and low maintenance wood pellet boilers available in the world.  Pellergy’s wood pellet boiler packages include everything you need for your pellet boiler system: From design planning to support maintaining your system and an exclusive extended manufacturer’s warranty.  Pellergy provided BioWIN2 wood pellet boilers are compact in design and offer various levels of features and performance.

The Windhager BioWIN2 Wood Pellet Boiler by Pellergy is a fully automatic system that incorporates:

• Fully automated burn chamber cleaning and ash removal
• Fully automated heat transfer surface cleaning
• Fully automated ash removal with an integrated ash collection box (Exklusiv Models) or a pull-out Ash Tray (LITE Models) to minimize required maintenance
• Firing rate modulation and advanced Thermocontrol allowing the boiler to fire down to 30% of its rated output
• 86+% Sustained Efficiency
• Standard North American Wiring: 120VAC, 60Hz ready

The BioWIN2 Series of pellet boiler incorporates one of the most advanced ignition systems on the market with a dual ignition element design. Having built in redundancy in the ignition system is unique and ensures the highest level of reliability.

The boilers are certified to UL-391, CAN/CSA-B366.1-11 and EN-303.5. The boilers are offered in two different functional series and three sizes.


The cutaway drawing in the figure to the left  shows the Windhager BioWIN2 Exklusiv wood pellet boiler with integrated vacuum transfer system for use with bulk pellets. Dimensional data on the units can be found here. The concept of operation of the system is very similar to many of the other European designed and built systems available today with the added features of a unique burn chamber design for automated cleaning, the incorporation of a dual ignition element and an integrated ash container with a convenient handle and wheels for ease of routine maintenance, required once every 2-3 Ton of pellets burned.





The BioWIN2 boiler burn chamber utilizes a unique and robustly engineered system consisting of two half-moon shaped discs that completely open to shed ash and clinker buildup. Ash lying on the “grate” is agitated, broken up and can fall below to the ash auger system for removal from the boiler either automatically (Exklusiv) or from the ash tray (LITE). This system has been proven in thousands of systems across the globe and hundreds in the US and Canada.


The installation of a BioWIN2 pellet boiler by Pellergy is simple. The system has been engineered for North American voltage: 120V AC, 60Hz, single phase power is all that is needed.  No wiring for 240V.

With the incorporation of a single vacuum suction probe as shown in teh figure to the Left, the BioWIN2 Touch Exklusiv Series of boiler can run for weeks, even months with no routine maintenance other than emptying the ash box. The single vacuum suction probe installation works well with an outdoor storage silo, custom site built bins and smaller 1-ton hoppers as well.

In larger storage rooms, or where more efficient pellet removal is desired, an auto changeover unit can be installed and accommodate three vacuum suction probes as shown in the Figure to the Right. In this installation, the auto changeover unit will pull pellets from each probe equally.

Where installations require larger than the output of one BioWIN2 pellet boiler, multiple boilers can be installed and cascaded through the use of a boiler management system. The boiler controls accommodate all standard US and Canadian boiler management systems and require only a simple normally open contact to activate. The Figure below shows the installation of three Windhager BioWIN boilers by Pellergy, each pulling pellets from a single pellet storage room configured with an auto changeover unit. Through cascading multiple smaller boilers, a space can be heated at peak efficiency throughout even the shoulder months of the heating season.  More information is available in the BioWIN2 Touch Exklusiv Pellet boiler brochure.
