The nonlinear heat-transfer equation in discontinuously heterogeneous, but piecewise homogeneous media is investigated. The existence of a weak solution in an enthalpy formulation is proved by using a Rothe method and a certain regularization of the contact conditions between the homogeneous subdomains. Phase transitions (described as a Stefan problem) and nonlinear boundary conditions are covered, too. Besides, the equation need not be of a strongly parabolic type.
