About BYenergie – Dlask Energy Retail
BYenergie is a trademark of Kern Mineralöl GmbH and represents an association of 16 experienced energy retailers in Upper Bavaria. The family business was founded in 1954 by Gustav Dlask as a coal merchant in Dachau and developed into a modern energy company that integrated heating oil as its core business. The offering includes the delivery of heating oil, diesel, wood pellets and AdBlue as well as tank protection, energy price consulting, fill-level monitoring (e-Peilstab plus) and mobile heat supply via the subsidiary Heizflex24. Own fuel storage facilities for solid and liquid fuels ensure on-time deliveries within the defined delivery area. Regional locations enable short delivery routes, e.g. to Munich, Augsburg and Rosenheim. Customers are private and business customers; the headquarters is located in the Günding industrial park (Bergkirchen).
