Free Flow FF17
The Free Flow is a highly effective, reliable, safe and long-lasting heating device. The outward functional form of the Free Flow has remained unchanged for forty years now because it simply cannot be improved upon as a design for a pure hot air stove. Having originally been conceived as a stand-alone wood-fired heating device – and often used as the only heat source – one of the key qualities of the Free Flow hot air stove has always been the fast and even heating of rooms.
Free Flow FF17
Lined with high-quality vermiculite and an improved combustion technology, the new Free Flow 2017 (FF17) meets all emissions requirements currently in force in Germany and Europe.
All Free Flow models are also available as a “Basic” version with all types. In this variant, the oven is supplied without thermal safety cover. When operated without covers, a distance to combustible materials of 70 cm must be observed only.
