Channel Heaters – Discreet Thermal Comfort

The Zehnder Terraline channel heater is the ideal solution wherever heating efficiency is combined with discreet design. The natural convection-based system ensures even heat distribution, while the concealed installation preserves interior aesthetics. This is an excellent choice for installers seeking reliable solutions and customers who value comfort and modern appearance.

Terraline heaters are characterized by rapid heating times and silent operation, translating into high user comfort. They perform exceptionally well in spaces with large glazing, creating an invisible barrier against cold air descending from windows. Integration with the Zehnder Comfosystems mechanical ventilation system further enhances system functionality and efficiency.

Construction and Materials

The heat exchanger is made from an aluminum-copper combination, guaranteeing high performance and durability. The heater casings are constructed from steel, ensuring a robust, corrosion-resistant structure. The entire unit is coated with a powder-coated paint finish in dark gray (RAL 7021), providing additional protection against mechanical damage and environmental influences. Note that the heater grille is sold separately and must be ordered independently, allowing customization to match the individual character of the interior.
