Specially developed vents with motorised dampers and attenuators are fitted into the wall of the building, allowing fresh air to be drawn in across the high-level heating elements. Fresh air is therefore preheated, and draughts associated with conventional ventilation are eliminated.
The dampers are initially controlled by carbon-dioxide concentration in the space, with the option of temperature over-ride. A rain sensor can be incorporated.
Finvector has a nominal output of 1100 W per linear metre at 75°C mean water temperature.
