  We study the high energy emission of two active galactic nuclei (AGN), NGC
4258 and NGC 7213. We directly apply the general-relativistic (GR) hot flow
model, kerrflow, to the archival BeppoSAX, NuSTAR and Suzaku observations of
these objects. Most of these data sets indicate that about 10-20 per cent of
the accretion power is used for the direct heating of electrons, however, we
find also indications for significant changes of the electron heating
efficiency in some cases. Furthermore, all these X-ray data sets indicate
rather strongly magnetized flows, with the magnetic field close to the
equipartition with the gas pressure. Comparison of the model prediction with
the Fermi/LAT data for NGC 7213 allows us to constrain the content of
nonthermal protons to at most 10 per cent.
