The Heating Process of a Furnace

Most older homes will rely on a furnace for heat in the winter. Furnaces are among the oldest types of heating systems for residential buildings. They were originally heated by wood or coal. However, most modern furnace systems use propane, gas or electricity to create heat in the home. These units are more energy efficient than other heating systems. Do you want to know how furnaces operate? Here is a quick guide on the heating process of a furnace.

Forced Air Heating

Electric, propane and gas furnaces all use forced air heating to warm your home. The system moves the heat throughout the home with air pressure. The blower fans push the air through a ductwork system in your home. This air then moves out through the vents. The furnace will use the same ductwork as the home’s air conditioning system. There is no need for additional ductwork.

Natural Gas Furnace

Natural gas furnaces use a pilot light to ignite burners in the combustion chamber. The heat from the burners enters a heat exchanger. From this point, the warm air is transferred and heats the ambient air. The blowers push the air throughout the ductwork system. Furnaces that use propane operate the same way.

Electric Furnace

An electric furnace operates on the same principle as a gas furnace. It uses an electrical ignition to begin the heating process. The ignition is activated by conductive coils in the system. When the electric current passes over the coils, these elements heat the air. That warm air will move to the blower area.
