The thermodynamic approach is applied to diffusion generated by an intermittent map on a grid of unit cells. The associated reduced map has two types of intermittent fixed points, one responsible for enhancing the diffusion, the other responsible for dispersing the diffusion. The dependence of the global characterization of the diffusion is investigated as a function of a pair of intermittency exponents that describe the strength of the intermittencies.
