Vaillant factory standardsstipulate strict requirements in this regard. The selectionprocess for choosing the raw materials takes intoaccount their recycling properties , the dismantlabilityand the separation facility of the component groups. Wealso take into account the environmental and healthdangers associated with the recycling and disposal ofnon-reusable remnants.10.1 UnitThe Vaillant ecoTEC consists to a large extent (up to92 %) of metallic components designed for recycling bymelting down in the steelworks. This gives these partsalmost indefinite reusability. All plastic materials aremarked properly which makes the separation andsorting more easy when the component group needs tobe recycled.10.2 PackagingVaillant strives to keep the scope of the transportpackaging for its units to an absolute minimum. Whenselecting the packaging material its subsequentreusability is taken into account. High quality cardboardhas been, for many years, a valuable raw material forthe paper and cardboard industry. The EPS components(Styropor®) are used for protecting the unit duringtransport. EPS is 100 % recyclable and CFC-free. The foilpackaging and securing straps are made from recyclableplastic.11 Vaillant serviceTo ensure regular servicing, it is strongly recommendedthat arrangements are made for a MaintenanceAgreement.
