CNS, Plus & Trend
Silent Convection Heaters
CNS Trend and Plus are modern surface-mounted convection heaters.
The sleek European slimline design works for stand-alone installation or
makes an effective, efficient replacement for traditional baseboard heaters,
accomplishing the same heating using significantly less room.
CNS heaters use natural convection for draft-free operation. Cool room
air flows in the bottom of the unit, is warmed by the heating element,
and rises silently out the top to heat the room. The CNS is designed with
a frost protection setting. The lowest thermostat setting will maintain an
appropriately-sized room above freezing temperatures. Overheat protection
is built in.
With its built-in thermostat, a single CNS is perfect as a stand-alone heating
system in bathrooms or small rooms. Multiple CNS units can be placed
strategically in larger spaces and their temperature settings adjusted
individually for maximum comfort control. If desired
CNS heaters may also be wired to use a separate
line voltage thermostat. In this case the Trend
models are recommended as the advanced features
of Plus models would not function.
The CNS Trend and Plus were engineered by Stiebel
Eltron in Germany and are manufactured to Stiebel
Eltron worldwide standards in our plant in China.
