The heating system consists of two linked and sealed housings (A1, A2; B1. B2) containing a variable speed fan, a heat exchanger (D) fed with hot water, and shutters (E, G) with connectors (F, H) for exterior cables. The fan is located by the first housing's intake and is able to draw in air and pass it through inner channels forming heating or cooling trajectories controlled by the shutters.
