Master equations are a powerful tool to perform quantum-transport calculations in non-equilibrium scenarios. We use a sequential-tunneling Redfield-type approach, which includes off-diagonal elements of the reduced density matrix, to study the thermoelectric properties of nanosystems. We examine how these off-diagonal elements alter physical observables. One point of particular interest is the linear response predicted by such an approach, especially the validity of the Onsager reciprocal relations. An interacting double quantum dot serves as an exemplary system to demonstrate our main results.
