Abstract

A hydronic air heater includes a frame assembly defining an enclosure, an inlet air damper formed in a wall of the enclosure and providing a means of ingress for ambient air, a closed heat transfer loop disposed within the enclosure, and a blower assembly disposed within the enclosure. The heat transfer loop includes a boiler for heating a fluid, a pump for circulating the fluid within the loop and a heating coil for receiving the heated fluid from the boiler. The blower assembly is configured to draw air into the enclosure through the inlet air damper and through the heating coil whereby heat from the fluid within the heating coil is transferred to the air.
