  Tilting the Weyl cone breaks the Lorentz invariance and enriches the Weyl
physics. Here, we report the observation of a magnetic-field-antisymmetric
Seebeck effect in a tilted Weyl semimetal, Co$_3$Sn$_2$S$_2$. Moreover, it is
found that the Seebeck effect and the Nernst effect are antisymmetric in both
the in-plane magnetic field and the magnetization. We attribute these exotic
effects to the one-dimensional chiral anomaly and phase space correction due to
the Berry curvature. The observation is further reproduced by a theoretical
calculation, taking into account the orbital magnetization.
