Domestic ventilationsystemsVitovent 300Ventilating virtually without energy lossVitovent 300Energy saving is the trump card of theVitovent 300. The powerful heat exchangerrecovers more than 90 percent of the latentheat contained in the stale air and uses itto heat the incoming air. Thanks to the veryefficient DC motors, for each kilowatt hour ofelectrical energy expended, 15 times moreheating energy is recovered. This means that300 litres of fuel oil could be saved in a yearfor a living area of 150 m 2 .Long term well-beingVitovent 300 constantly replaces the ambientair and simultaneously removes odoursand noxious substances.
