    The Zehnder Terraline trench heater offers an elegant alternative wherever free-standing radiators should be avoided for reasons of aesthetics or underfloor heating is not possible. All that is visible is the frame, complete with integrated decorative grille. Zehnder Terraline utilises the rising warm air to create pleasant, natural warmth. The trench heater is ideal for use where there are large areas of full height glazing.
