Commercial unit heaters provide space heat to small areas.
Unit heaters are best suited for smaller industrial and commercial facilities with relatively low ceilings, or larger places where even temperature distribution is not critical. For example, unit heaters can be typically found in the entrance to a retail store, or just inside the building near the loading dock. They are also used in manufacturing plants to provide spot heating in areas where employees are stationed.
III Equipment Options
Some modern unit heaters are condensing units, which condense flue gases and increase efficiency. Other models preheat incoming air using flue gases.
Unit heaters are available in sizes ranging from 10,000 BTU to over 600,000 BTU.
