Abstract: The invention concerns a heater made of a material (5) responsive to induction and capable of sustaining high temperatures. It further comprises at least an insulating thickness with low thermal conductivity, in particular a low temperature insulation (3) and a high temperature insulation (4), said thickness being fixed at the back of the material. A field winding (2) is adjacent to the insulating thickness and separated from the material (5) by the latter.

Abstract: 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.
