Gas Furnace Heat Exchanger Rust

Once a furnace is in service long enough the heat exchanger will eventually crack simply from the built.

Gas furnace heat exchanger rust. If this condensation isn t cleaned out or disposed of properly the heat exchangers could rust. A furnace is a reliable and energy efficient way to provide heating for pacific northwest homes. There are a number of ways that your heat exchanger can become damaged or cracked. As your furnace ages you may start to notice problems such as rust.

This combustion process generates heat energy from the fuel source. To create heat your furnace combusts fuel typically gas but other varieties exist in a sealed chamber. Sometimes condensation occurs with gas furnaces. It might seem as if a few spots of rust are no big deal but the concern is corrosion along the heat exchanger.

Corrosion weakens metal and this can allow the heat exchanger to crack and toxic combustion gases to seep into. The heat exchanger is commonly referred to as the heart of your heating system. The combustible gas will become hotter as it accumulates in the exchanger. If a heat exchanger starts to corrode it can develop cracks which.

There are certain signs to look for to determine if the heat exchanger has been. If cracks occur in a heat exchanger because of the weakening effect of rust it can lead to dangerous carbon monoxide leaks. Rust poses a particular danger to your furnace and you. Every furnace contains a heat exchanger.

It s an essential part of the heating process. A furnace that has worked effectively for 20 years has more than lived up to its potential and it is probably time to retire it before it retires itself at a very inconvenient time. You don t want this to occur to your furnace especially along the heat exchangers. Corrosion across the heat exchanger.

Signs your furnace has a cracked heat exchanger. If the burners on your furnace aren t combusting the gas properly they could burn hotter heating up the metal of the heat exchanger to higher temperatures causing cracks. Proper maintenance annual fall furnace tune ups can help a furnace last a long time but wear and tear eventually takes its toll. What is the furnace heat exchanger.

It has also been called the hot box the fire chamber and others and is simply the area where the flames enter your system. The great danger of rust to metal is that it eats away at the metal and eventually causes it to crumble and flake away. Today i am writing about furnace heat exchangers and how rust in the exchanger can tell you about the condition of your gas furnace. If a heat exchanger becomes cracked then your heating system will not perform as it should.

Consequently air temperature becomes hotter.
