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. Lined with high-quality vermiculite, the Free Flow 2017 (FF17) meets all emissions requirements currently in force in Germany and Europe.
The striking and logical design of the Free Flow is so unique that it makes a positive statement in any sur- roundings. It is equally at home in the countryside, in town, or in the workshop. As such, the Free Flow also stands out for the way its appearance and operation can be adjusted. The combination of side-covers or stor- age ceramic, bases and handles allows you to design your Free Flow to best suit you and the space where you intend to install it. Different nominal heat output ratings (6.8 to 14.2 kW) allow it to be used not only in small but also in very large space.
The Free Flow is a hot air stove in its purest form. Air from the room is quickly heated in the convection pipes without direct contact with the fire and rises up (thermal convection effect). Cooler air from the room flows up into the pipe and is also heated. The undetectable flow of air created in this way spreads the heat immedi- ately, quickly and evenly into the spaces to be heated. Due to these exceptional heating qualities, the Free Flow is often used in spaces with complex layouts, or in sporadically heated areas such as function rooms or conservatories.
