ABSTRACT:
In a hot air type heating apparatus having two air outlet ports, a temperature of air current blown out of an auxiliary outlet port provided on an outlet port for a high temperature air is rendered to be at a slightly warm temperature level, thereby realizing an improved hot air type heating apparatus capable of distributing warm air to every corner of a large room to effect uniform room warming, and of removing uncomfortableness to a dweller near the heating apparatus owing to a temperature difference caused by the two air currents blown out of the two outlet ports.
