Description
Heatmann Line trench water convectors deliver elegant, silent and energy-efficient heating for rooms with panoramic windows and glass walls. Installed flush with the floor, they form a warm air curtain along the glazing.
A thermal curtain along panoramic windows
The unit works by natural convection: warm air rises and creates a continuous flow along the windows. This curtain prevents drafts and condensation on the glass while keeping an even, comfortable temperature in the room — without blocking the view. No fans, no noise, no dust movement.
Energy efficiency and savings
The high-performance copper-aluminium heat exchanger needs up to ten times less water than a steel radiator of equivalent output. That means faster warm-up, lower energy use and reduced running costs — especially together with a heat pump and low-temperature systems.
Materials and durability
The heat exchanger is built from copper, aluminium and brass — metals with excellent heat conductivity. Internal parts carry a protective graphite-grey lacquer that resists dust, corrosion and wear, so Line performs reliably in homes, offices, hotels and showrooms.
