Heat-recovery ventilation
EnviroVent’s heatSava through-the-wall single-room heat-recovery unit is described as ideal for retrofit and new-build projects. It recovers up to 75% of the heat that would normally be lost on extraction, whilst providing continuous all-year-round good indoor air quality.
There are two sizes — 100 mm for bathrooms and WCs and 150 mm for kitchens. The 100 mm size is available as a low-voltage version. They can use an existing wall sleeve or be installed into a new wall.
The heatSava fits neatly into almost any external wall. The heat cell comes in four lengths to suit wall thicknesses from 310 to 600 mm. These units can be installed in four positions horizontally or vertically.
