The heat exchanger is the metal wall or tubing that is heated up when the burners are ignited. The inside of the heat exchanger allows the toxic flue gases produced from the burners to exhaust out through the furnace flue.
The outside of the heat exchanger is where the cold air passes over, becomes warmed, and is blown throughout the ductwork of the home. The heat exchanger is the only wall separating the toxic flue gases from the supply air.
If a crack develops in the heat exchanger, there is a potential for carbon monoxide gas to leak over to the supply side and be blown throughout your rooms. Carbon monoxide gas is odorless. The human senses will not detect its presence.

How to repair hairline crack on furnace heat exchanger?
Repairing a hairline crack in a furnace heat exchanger is best left to professionals, as it involves safety concerns with gas and combustion. If you suspect a crack, first turn off the furnace and shut off the gas supply. A technician may use a specialized heat exchanger repair kit or replace the unit if the damage is significant. Always consult a licensed HVAC technician for a thorough inspection and proper repair to ensure safe operation.
How hot does a gas fired heat exchanger get?
There are specific values for heat rise across a furnace heat exchanger given in all installation/operation manuals for all furnaces. As long as these limits are adhered to by the installer the heat exchanger will not overheat. I know this does not answer the question but there is no one blanket answer for all furnaces. Basically the more airflow through the furnace, the lower the HX temp and to determine when the airflow is correct a heat rise test is done and the airflow is set to the mid point of that specification.
Why is the boiler water circulating pump required for EGB?
I think because it works more like a heat exchanger taking heat from the exhaust gas, rather than a "standard" boiler with a furnace?An EGB needs a pump to circulate the water through the pipes in the exhaust stack, whereas a furnace-heated boiler can use convection to move the fluid through the system..?Might have something to do with lower temperatures in an EGB?
Why Expansion bellows are required in heat exchanger?
expension belows are used for heat exchanger to avoid thermal stress
What safety precautions should be taken before cleaning a heat exchanger?
Prior to cleaning a heat exchanger, one should be sure to use hand, body, and eye protection. One should not conduct acid and bleach flushing simultaneously, as this produces a noxious gas which can be lethal if inhaled for an extended period of time.
A condensing gas furnace uses from a condensing type heat exchanger to increase the furnace efficiency?
Yes
Does a forced air furnace have a heat exchanger?
Yes,It depends if it is gas fired or electric.
What is the cost of a heat exchanger for a furnace?
The cost of a heat exchanger for a furnace can vary depending on the size and type of furnace, but typically ranges from 300 to 1500.
What is the cost to replace a furnace heat exchanger?
The cost to replace a furnace heat exchanger typically ranges from 500 to 2,000, depending on the type of furnace and the complexity of the installation.
What are the steps involved in furnace heat exchanger replacement?
The steps involved in furnace heat exchanger replacement include turning off the power to the furnace, removing the old heat exchanger, installing the new heat exchanger, reconnecting all components, testing the furnace for proper operation, and ensuring everything is working correctly before turning the power back on.
What is the typical cost of replacing a furnace heat exchanger?
The typical cost of replacing a furnace heat exchanger can range from 500 to 2,000, depending on the type of furnace and the complexity of the installation.
Will replacing the heat exchanger prolong the life of your furnace?
The heat exchanger in a furnace is the primary component in a furnace. That said, their are circuit boards, motors and other components that can also fail regardless of the age of the heat exchanger. In my opinion, if you can afford to replace the furnace, you would be much better off. The cost of the heat exchanger with labor is probably not too much less than replacing the entire furnace.
What is the average cost of furnace heat exchanger replacement?
The average cost of furnace heat exchanger replacement is typically between 500 to 2,000, depending on the type of furnace and the complexity of the job.
What is a furnace with a vertical air flow through the heat exchanger and the blower compartment beneath the heat exchanger called?
A furnace with a vertical air flow through the heat exchanger and the blower compartment located beneath the heat exchanger is typically called a "downflow furnace." This design allows air to be drawn in from the top, heated as it passes through the heat exchanger, and then expelled from the bottom into the living space. Downflow furnaces are commonly used in applications where the furnace is installed in a basement or crawl space.
How do gas furnace burners function to produce heat in a heating system?
Gas furnace burners function by mixing natural gas with air and igniting it to create a controlled flame. This flame heats up a heat exchanger, which then transfers the heat to the air that is circulated throughout the heating system.
What is a furnace with a horizontal heat exchanger called?
air handler
