A large heat supply system, which always has a multi-level hierarchical structure, is considered. There are levels of trunk and distribution heating networks with intermediate levels of regulation. Planning and selection of a mode that provides the required heat loads are associated in such a system with a large number of different factors that complicate the decision-making process. The present study investigates heat transfer in a flat anisotropic insulating plate with uniformly distributed internal heat sinks subjected to heat flows. An analytical solution is obtained that allowed us to study and build temperature distribution fields for various orientations of principal axes of thermal conductivity tensor in an insulating plate. The thermal field localization regime is shown to be possible in the presence of thermal energy sinks/sources inside the plate wherein heat propagation is bound with limiting isotherms.
