1. A device for providing a reducing agent for an exhaust gas system, the device comprising:
a housing; a system heating unit configured to heat the reducing agent; at least one heat pipe being a sealed hollow body having a fluid provided therein, said fluid being partially in a gaseous phase and partially in a liquid phase, said at least one heat pipe being configured to transfer heat from said system heating unit to at least one of the following components: a tank, a delivery line, a filter, a pump, a valve, or a sensor; a delivery module disposed in said housing and including at least said filter, said pump, said valve and said delivery line, said delivery module being configured for removing the reducing agent from the tank, transferring the reducing agent onward and dispensing the reducing agent; said system heating unit being integrated into said delivery module and forming a sole active heating system; and said at least one heat pipe connecting said system heating unit in a heat-conducting manner at least to one of said filter, said pump, said valve or said delivery line.
