ABSTRACT OF THE DISCLOSURE A forced air circulation heating apparatus in which an air stream is heated at a first location in a conduit means and transported to a second location within the apparatus by the conduit means and is forced into a heating compartment and mixed with a recirculated forced air flow within the compartment. A valve or controller means can be used to vary the proportions of the heated air stream and-the recirculated forced air flow which are combined within the heating compartment. The air conduit and the heating compartment can have a common wall whereby the heated air stream indirectly heats the heating compartment. A dual flow impeller fan is used to move the heated air stream and to establish the recirculated forced air flow within the heating compartment. The fan operates with a single electric motor. The heating compartment is vented to a flueway.
