This article is focused on the study of a convection problem in a 2D set-up in the presence of the O(2) symmetry. In the fluid, viscosity depends on the temperature by changing its value abruptly in an interval around a temperature of transition. We explore the morphology of the plumes for several parameter settings in the viscosity law and perform bifurcation studies at several aspect ratios. We report that at a large aspect ratio and high Rayleigh numbers, travelling waves, heteroclinic connections and chaotic regimes are found, which are greatly influenced by the presence of the symmetry.
