The heat exchanger is commonly referred to as the heart of your heating system.

Gas furnace heat exchanger rust.

Factors that damage your heat exchanger. Corrosion weakens metal and this can allow the heat exchanger to crack and toxic combustion gases to seep into. You don t want this to occur to your furnace especially along the heat exchangers. Once a furnace is in service long enough the heat exchanger will eventually crack simply from the built.

The combustible gas will become hotter as it accumulates in the exchanger. Proper maintenance annual fall furnace tune ups can help a furnace last a long time but wear and tear eventually takes its toll. Consequently air temperature becomes hotter. If this condensation isn t cleaned out or disposed of properly the heat exchangers could rust.

This combustion process generates heat energy from the fuel source. A furnace is a reliable and energy efficient way to provide heating for pacific northwest homes. If a heat exchanger starts to corrode it can develop cracks which. Sometimes condensation occurs with gas furnaces.

Read on to learn more about what causes your heat exchanger to rust or crack and how to address the damage. What is the furnace heat exchanger. Every furnace contains a heat exchanger. If cracks occur in a heat exchanger because of the weakening effect of rust it can lead to dangerous carbon monoxide leaks.

Today i am writing about furnace heat exchangers and how rust in the exchanger can tell you about the condition of your gas furnace. To create heat your furnace combusts fuel typically gas but other varieties exist in a sealed chamber. It has also been called the hot box the fire chamber and others and is simply the area where the flames enter your system.
