Abstract
A heating system with wraparound heat exchanger is disclosed. The system includes a centrifugal fan that expels air radially into a plenum space. A heat exchanger tube is placed in the plenum space, thereby heating the air in the plenum space before it exits an assembly cabinet. The heat exchanger tube can have various configurations, including non-horizontal configurations so as to allow condensate to drain from the heat exchanger tubes.
