This short note is a response to the comment on our recently published paper cited in the title. All points raised by the author of the comment are discussed. It is shown that one of the remarks, concerning eigenflow solutions in the limiting case of forced convection, does not have a sound physical basis. In fact, it refers to a circumstance, a fluid with a thermal expansion coefficient greater than that of a perfect gas, of marginal or no interest in the framework of convection in porous media.
