BioWIN2

THE pellet boiler

The BioWIN2 from Windhager is THE pellet boiler for long-term, carefree heating. It embodies the know-how and experience gained from four

generations of pellet boilers, which have already completed 1 billion hours of service. Every component of the BioWIN2 is therefore carefully designed and state-of-the-art, making heating with pellets even more convenient, economical and reliable. The best demonstration is that Windhager provides a five-year full guarantee for the boiler, stainless steel burner and ignition element.

A miracle of efficiency BioWIN2 Plus: The BIOWIN2 is also available as a pellet condensing boiler. In addition to its proven benefits, it delivers more heat.

Thanks to its patented ash-sliding grate that runs in the opposite direction, no residue is left in the pellet boiler. This significantly increases its operating safety and makes it resistant to any fluctuation in the pellet quality

The patented low-wear ignition element runs silently, is robust and requires no maintenance

The innovative stainless steel burner is so clean and efficient that the BioWIN2 Touch is several times better than even the strictest statutory emission limit values.

The ash box is extra large so offers plenty of capacity and this, coupled with the efficient boiler combustion, ensures long emptying intervals.
