It is shown that the Bethe ansatz formulation of the easy-plane 1D Heisenberg model thermodynamics (TBA) by Takahashi and Suzuki and the subsequent analysis of the spin Drude weight, also reproduces the thermal Drude weight and magnetothermal coefficient obtained by the Quantum Transfer Matrix method (QTM). It can also be extended to study the far-out of equilibrium energy current generated at the interface between two semi-infinite chains held at different temperatures.
