  We study the thermal drag between two mesoscopic quantum Hall (QH) circuits.
Each circuit consists of Ohmic contact perfectly coupled to quantum Hall edge
states. The drag is caused by strong capacitive coupling between Ohmic
contacts. The non-equilibirum conditions and the electron-electron interaction
are taken into account by using the non-equilibrium bosonization technique. The
thermal drag current in the passive circuit, the noise power of the
corresponding heat current, and the Fano factor are calculated and analyzed.
