A heating convection unit and a method of mounting the same, provided with an envelope having a front face, a rear face, a top, a bottom and peripheral side walls. The front face and the peripheral side walls define an inner enclosure. The unit is also provided with a medial shield having front face, a rear face, a top, a bottom and peripheral side walls. The medial shield is mounted within the inner enclosure defined by the envelope and spaced apart therefrom. The rear face and peripheral side walls of the medial shield and the front face and peripheral side walls of the envelope define a ventilation passage having top and bottom openings in communication with ambient air. The medial shield preferably has an intermediate opening communicating with the ventilation passage. The unit is also provided with a cover having a front face, a rear face, a top and a bottom. The cover is fixed over the medial shield. The cover has top and bottom openings in communication with the ambient air. The top and bottom openings of the cover communicate with the top and bottom openings of the ventilation passage. The rear face of the cover and the front face of the medial shield define a convection passage between the top and bottom openings of the cover. The unit also has a heating element located inside the convection passage for heating the ambient air. The heating element is located proximate to the bottom opening of the cover. The intermediate opening of the medial shield is located above of the heating element.

A ventilation unit for use with a heating or cooling system that is decentralized and does not require large conduits is disclosed. The system includes at least one fresh air intake; a fan operatively connected to the at least one fresh air intake for drawing air from outside of a space into the fresh air intake; and at least one ventilation unit located in the room. The ventilation unit includes a conduit defining an air passage having a first and second opposite ends, a diffuser operatively connected to the fresh air intake for outputting fresh air near the second opposite end of the conduit and for drawing ambient air from the room through the first opposite end. The ventilation unit also includes a heating element located downstream from the first opposite end inside the conduit. The ambient air is entrained towards the heating element which heats the ambient air, and the heated air is ventilated into the room at the second opposite end of the conduit by the action of a chimney effect and the fresh air diffuser. The system provides for adequate ventilation through the use of small conduits due to the decentralized heating of the air.
