Fanassisted trench heater VKN5 was designed for spacious interiors with numerous glazings. The use of a modern fan with low power consumption and very quiet operation does not interfere with the comfort of users. Precise and easy control is provided by user-friendly room air temperature controller.
The use of an economical fan made it possible to obtain a heating device with greater heating output and shorter response time. In addition, the low thermal inertia, as well as the use of electronic control allows to achieve savings in the heating season of more than 20%.

Fan assisted trench heater VKN5 Verano is ideal for low-temperature systems. A major advantage of this type of heater is the even distribution of heat throughout the room.
