The invention relates to a tank withdrawal system for a vehicle tank filled with a frozen liquid. The tank withdrawal system comprises a heating system comprising at least one electric heating element as primary heating device and a conduit system provided with at least one withdrawal conduit with a withdrawal opening arranged in the vehicle tank. The cold start volume of the frozen liquid extending around the withdrawal opening can be melted by the primary heating device. To quickly melt a cold start volume while melting off the remaining frozen liquid consuming as minimal amount of energy, the heating system comprises a secondary heating device supplied with a heating fluid and the conduit system comprises at least one heating conduit through which the heating fluid can flow and which is arranged in the liquid in the vehicle tank.
A tank withdrawal system for a vehicle tank adapted to store a liquid, the tank withdrawal system comprising a heating system and a conduit system, the heating system comprising at least one electric heating element and a secondary heating device, the conduit system comprising at least one withdrawal conduit with a withdrawal opening, the withdrawal opening configured to be positioned in the vehicle tank, the at least one electric heating element adapted to melt a cold start volume of the liquid extending around the withdrawal opening, the conduit system further comprising at least one heating conduit which is adapted to be passed through by a heating fluid and which is configured to be positioned in the liquid in the vehicle tank, and that the heating conduit is connected to the withdrawal conduit in a liquid conveying manner such that molten liquid serving as heating fluid is fed to the heating conduit through the withdrawal conduit, and a withdrawal unit with a housing configured to be inserted into the vehicle tank through a mounting port in one piece and to be immersed at least partially into the liquid contained in the vehicle tank, wherein the withdrawal unit comprises a section of the withdrawal conduit comprising a withdrawal opening and electric heating elements.
A tank withdrawal system for a vehicle tank adapted to store a liquid which is susceptible to freezing under low temperature conditions, the tank withdrawal system comprising:
