This paper investigates the dynamics of current and efficiency in a bosonic system consisting of a central system interacting with two reservoirs at different temperatures. We derive a master equation describing the time evolution of the density matrix of the system, accounting for the interactions and energy transfer between the components. We quantify the current, representing the flow of bosons through the system and analyse its dependence on the system's parameters and temperatures of the thermal reservoirs. In the steady state regime, we derived an expression for the efficiency of the energy transfer process. Our analysis show that quantum effects, such as the dependence on temperature and the quantum correction factor, can significantly impact energy transfer efficiency. In particular, we observe that at high temperatures, the efficiency of the quantum system is greater than the Carnot efficiency. The insights gained from this analysis may have implications in various fields, including quantum computing and energy harvesting, where optimising energy utilisation is crucial.
