Description
The First Company 9-315-4-4 Heater H-103 is used to produce additional heat in air-handling elements in HVAC systems. This electrical current flows through resistance heating components rated at 8 kilowatts on a 240-volt power supply, generating heat that the air stream flowing through the air handler section absorbs. This is connected to the unit’s power circuit and control wiring, allowing it to be turned on when needed. It is placed inside the heater section of the air handler, where the temperature of the circulating air is raised.
