Channel Heater – Discreet Comfort and Efficient Heating

The Zehnder Terraline channel heater is the ideal solution for those who value aesthetics and functionality. Its design allows for nearly complete concealment of the heating system, leaving visible only an elegant frame and grille. This is an excellent choice for spaces with large glazing, where traditional radiators might disrupt interior harmony. The device utilizes natural convection to ensure even heat distribution and create a comfortable microclimate.

The Terraline heater consists of a durable, galvanized and powder-coated housing and a high-efficiency heat exchanger made of aluminum-copper combination. This construction guarantees not only heating efficiency but also long-term reliability. The maximum operating pressure is 10 bar, and the operating temperature reaches 110°C, making it safe and resistant to failures. With a heating output of 903W (at ΔT = 50°C), it ensures effective room heating.

Design and Installation – Flexible Adaptation to Your Needs

Zehnder Terraline offers great flexibility in installation and configuration. Available in a length of 1800 mm and width of 340 mm, it can be connected into longer runs or customized to individual dimensions. Note that since April 2020, the grille must be ordered separately, allowing you to choose the most suitable model—either rolled or linear—made from aluminum, wood, or stainless steel. Decorative frames are available in anodized aluminum, either in natural finish or matched to the selected grille.

Benefits for Installers and End Users:

• Fast heating time: The heater rapidly reaches the set temperature, delivering thermal comfort in a short time.
• Invisible heating system: The concealed design preserves interior aesthetics without compromise.

The Zehnder Terraline heater is an investment in interior comfort and aesthetics, appreciated by professional installers for its ease of installation and reliability, and by end users for its discreet design and efficient heating performance.
