How Gas Heaters Work

Gas heaters utilize a combustion process to generate heat. The fuel, either natural gas or propane, is burned in a combustion chamber. This process produces hot gases, which are then circulated through the heater’s heat exchanger. The heat exchanger transfers the heat to the surrounding air, which is then distributed throughout the space by a fan or blower.

Components of Gas Heaters

Gas heaters consist of several key components, including a control valve, pilot light or electronic ignition, burner assembly, heat exchanger, and blower or fan. These components work together to ensure the safe, efficient operation of the heater.

Understanding Electric Heaters

Electric heaters, on the other hand, rely on electrical power to generate heat. They work differently from gas heaters, employing various technologies to produce warmth and distribute it effectively.

How Electric Heaters Work

Electric heaters use electrical resistance to generate heat. When an electric current passes through a resistive element, such as a coil or ceramic disk, it produces heat. This heat is then dispersed into the surrounding area through convection or radiant heating.

Types of Electric Heaters

There are several types of electric heaters available, each with its unique advantages and applications. These include convection heaters, radiant heaters, fan-forced heaters, and infrared heaters. Convection heaters warm the air through natural convection currents, while radiant heaters emit infrared radiation to directly heat objects and people in their vicinity.
