HydroTherm Haustechnik GmbH, the Seidenberger family and team, supports the family audiobook in December. The company from the Lower Bavarian district of Landshut was made aware of the project by a grandmother, whose granddaughter is allowed to grow up with a family audiobook. It is always something special when the impetus to donate comes directly from an audiobook family. Who better to underline what such a grief aid means?
