A ventilation unit for use with a system for heating and ventilating an enclosed space, said ventilation unit including a conduit defining an air passage having a first and second opposite end, said first opposite end lying proximate a floor, said second opposite end extending in a direction opposite said floor, a heater located inside said conduit proximate said first opposite end, said conduit having a central portion between said two opposite ends that is substantially vertical, said second opposite end lying in a plane substantially perpendicular to said floor, a fresh air diffuser located behind said conduit and having an outlet proximate said second end, said ventilation unit drawing ambient air through said first opposite end due to a chimney effect created by said conduit, due to said heater which heats said ambient air and forces said heated ambient air to rise, and due to said fresh air diffuser which propels said heated air out of said conduit at said second end and at an angle with respect to vertical into said space and entrains said ambient air through said conduit.
