We study the heat transfer between weakly coupled systems with flat interface. We present a simple analytical result which can be used to estimate the heat transfer coefficient. As an application we consider the heat transfer between graphene and amorphous SiO2. The calculated value of the heat transfer coefficient is in good agreement with the value deduced from experimental data.
