At what temp does a chimney fire start?

How Hot Do Chimney Fires Get? As we mentioned a little bit earlier, creosote has the potential to ignite at around 451 degrees F. Given that fires in fireplaces can reach temps exceeding 450 degrees F, it doesn't take a miracle for creosote to reach the right temperature for a chimney fire.

What temp does creosote ignite?

The Dangers of Creosote

Creosote is highly combustible and is well known for its fire threat in chimneys of wood-burning fireplaces. Creosote's flash point (the lowest temperature at which vapors will ignite when given an ignition source like a spark or flame) is surprisingly low at 165-degrees Fahrenheit.

What percentage of heat goes up the chimney from an open fire?

Putting a Damper on Your Energy Bills

What's more, between 80 and 90 percent of the heat produced by wood burned in an open fireplace is lost up the chimney. This means that for every $100 you spend on firewood, you get only $10 to $20 worth of heat. The rest goes up the chimney.

Can a chimney fire burn your house down?

In the most severe cases, chimney fires can destroy houses and put lives at risk. These tragedies are often preventable: Failure to regularly inspect, repair, and clean a chimney can cause it to malfunction or collect dangerous build-up that puts your family at risk.

Will a hot fire remove creosote?

One method to loosen crusty or tarry creosote so it flakes off and falls down into the firebox or fireplace is to burn aluminum cans in a very hot fire. While this method works, it does not clean the chimney of creosote completely, and chimney brush cleaning is still necessary.

Does an open chimney lose heat?

Open fireplaces will be losing you heat; they help to cool your home. In the past when chimneys were used with fires, the chimney stack would create a draw which naturally caused warm flue gases to flow up the chimney, out through the pots and away.

Do chimneys let cold air in?

A fireplace is a huge source of drafts from the cold outdoors. A chimney can act as a wind tunnel even when the damper is closed, sucking cold air down into your home through the fireplace opening.

How do I stop a chimney draft?

Can a chimney fire reignite?

Can I relight the fire once the chimney fire is extinguished? You MUST Have the chimney swept before relighting the fire! If you have any concerns that the chimney or flue is damaged ensure that it is inspected by either a qualified chimney sweep, builder or engineer before the fire is relit.

What temperature does a wood burning stove reach?

Not only will you literally burn through your fuel way too fast, but a lot of the heat will escape straight up the chimney. To get the most heat from your wood burning stove, the temperature should be between 260 and 460°C. Any lower than this, your fire will be burning too slow to generate a good amount of heat.

Are chimney fires common?

There are over 25,000 reported chimney fires a year in the U.S. While some sound like a low-flying jet and include flames shooting out the top of the chimney, others are slow-burning and go undetected until a chimney inspection uncovers damage. Chimney fires are dangerous, but they are preventable.

Does burning salt clean a chimney?

Sodium chloride, also known as table salt, is a simple chemical that is easy to find. Put a little salt in the fire while it is burning. The salt combines with the water in the burning wood to create a weak acid that travels up the chimney and dissolves small amounts of creosote.

Where does a chimney fire start?

Where Do Most Chimney Fires Start? Most chimney fires start inside the flue where there's either creosote buildup or a flue blockage of some kind. As heat from the fire reaches these flammable materials, the creosote or blockage ignites, starting a chimney fire.

What dissolves creosote?

Vinegar is a natural acid that will break down the creosote over time. All you have to do is pour vinegar onto the creosote and then wait for it to dissolve. If you want to take a more natural approach, try dissolving the creosote using salt water instead of vinegar or chemical cleaners.

What cleans up creosote?

Try using lard, WD-40, butter, chicken fat or olive oil on a rag. The oils combine with the creosote allowing it to lift off the fabric with a clean rag. Wipe the oil in one direction with a lifting motion so as not to smear it into a larger area. Wipe it in the direction of the threads when possible.

How do you test a chimney for creosote?

Use your fireplace poker.
