Can You Use a Wood Stove with Cracked Glass?

If you’re like many homeowners, you may use a wood stove to help heat your home during the colder months. Wood stoves are a great way to save money on your heating bill, and they provide a cozy atmosphere for your family. However, if your wood stove has a cracked glass door, you may be wondering if it’s still safe to use.

Using a wood stove with cracked glass is extremely dangerous. You risk serious injury if the glass were to shatter while the stove is in use. Cracked glass can also cause the wood stove to operate less efficiently, as heat can escape through the cracks. 

In this blog post, we will discuss the dangers of using a wood stove with a cracked glass door and offer some tips for safely operating your stove.

Is It Safe to Use a Wood Stove with Cracked Glass?

You’ve been using your wood stove all winter and everything has been going great. But then, one day, you notice that the glass door on your stove is cracked. You’re not sure how it happened, but now you’re wondering if you can use your stove with a cracked door.

The short answer is no. You should not use your stove with a cracked door. Cracked glass can pose a serious safety hazard and make your stove less efficient. Here’s why:

Danger of Injury From Shattered Glass

The cracked glass could shatter if you continue using your wood stove at high temperatures. This poses a danger of injury, as shards of glass could fly into the room and cause cuts or even puncture someone’s eye.

Reduced Efficiency

Another reason you should not use your stove with cracked glass is that it will be less efficient. Cracks in the glass door will let heat escape, making the stove less effective in heating your home. In addition, the cracked glass will also let in more air, which can cause the fire to burn less efficiently.

So, if you have a wood stove with cracked glass, it’s best to replace the door or get a new stove altogether.

Why Does Wood Stove Glass Crack?

It’s crucial to know why wood stove glass cracks in the first place. After all, if you know the reason, you can hopefully prevent it from happening again.

There are a few reasons why wood stove glass might crack:

Sudden Changes in Temperature

One of the most common reasons for cracked wood stove glass is sudden temperature changes. When you light a fire, the glass will heat up quickly. If you then open the door or put more wood on the fire, the sudden influx of cold air can cause the glass to crack.

It’s essential to heat the glass gradually to prevent this from happening. You can do this by lighting a small fire and slowly adding more wood.

Another way to prevent sudden temperature changes is to keep the door closed as much as possible.

Faulty Installation

If the wood stove wasn’t installed correctly, the glass will likely crack in the event of a fire. This is because the glass isn’t adequately supported and can’t withstand the heat. Therefore, it’s crucial to ensure the installation is done by a professional.

Extreme Temperatures

A wood stove glass may also crack if exposed to extreme temperatures. This can happen if the stove is left on for too long or if you burn the wood at extremely high temperatures.

Strong Impact from Outside Elements

The glass on a wood stove may also crack if a hard object hits it. This can happen if something falls on the stove or if someone accidentally bumps into it.

Therefore, it’s essential to be careful around the wood stove and ensure that nothing can fall on it.

To ensure this doesn’t happen, always follow the manufacturer’s instructions and don’t use the stove to heat your home above the recommended temperature.

Burning Household Charcoal in the Wood Stove

Burning household charcoal in the enclosed space of a wood stove can result in mini-explosions that will cause the glass to crack.

The fumes from burning charcoal are also hazardous and lead to carbon monoxide poisoning. Therefore, it’s essential to only burn wood in your wood stove and never use it to burn charcoal.

How Do You Repair a Crack in a Wood Burning Stove?

Can stove glass be repaired? Yes. If the crack is small, you may be able to repair it with a high-temperature adhesive or sealant. However, if the crack is large, you will need to replace the entire piece of glass.

When replacing the glass, be sure to use a heat-resistant variety that is rated for your stove’s temperature. Next, follow the steps below to replace the glass:

  • Clean your wood stove door to make removing the glass a hassle-free process.
  • Open the glass door. This step will make accessing the screws holding the door in place easier.
  • Next, release the screws holding the door in place using a screwdriver.
  • Replace, and reseal your new glass panel

If you don’t think you’re up to the task, you can always consult a professional. Be sure to have the model and make of your wood stove on hand, as this will help the professional determine which glass panel you need.
