How furnace works diagram
The diagram of a furnace shows how this essential home appliance operates to keep your living space warm and comfortable. The heat exchanger is at the heart of the furnace, which transfers heat from the combustion gases to the air circulating throughout your home. The furnace’s burners ignite a fuel source, typically natural gas or propane, to create heat, which is then transferred to the heat exchanger. The blower motor then pushes air over the heat exchanger, warming it up and distributing it through your home’s ductwork. As the warm air circulates, it raises your home’s temperature to your desired level, and the furnace’s thermostat regulates the temperature by turning the burners on and off as needed. To ensure your furnace operates safely and efficiently, it’s essential to have it regularly maintained by a qualified HVAC technician. Following this diagram and caring for your furnace can keep your home warm and comfortable all winter.
