Simply and very efficiently. Outside air is drawn into the loft where it is slightly warmed by the free heat in the loft caused by solar radiation and the heat lost from the property into the loft. This air is drawn into the unit, filtered and then ducted into a central area (typically the hallway / stairwell) of the dwelling. As the air is supplied into the dwelling it mixes with the warmer air that naturally accumulates at ceiling level taking advantage of the heat from this warm air you have paid for but are not making use of. This tempered fresh clean air then continuously and gently dilutes displaces and replaces the air within your home. The result is a home free from serious condensation and a
more pleasant and comfortable environment.
