How To Build A Wood Burning Fireplace Insert

A wood-burning fireplace insert is a great way to add warmth and ambiance to your home. Inserts are also more efficient than traditional fireplaces, meaning you'll use less wood and save money on heating costs. If you're considering adding a fireplace insert to your home, there are a few things you'll need to know before you get started. First, you'll need to determine if your existing fireplace is compatible with an insert. Second, you'll need to choose the right size and type of insert for your needs. Finally, you'll need to install the insert properly to ensure it's safe and efficient.

Determining Fireplace Compatibility

Not all fireplaces are compatible with inserts. Before you begin your project, you'll need to determine if your existing fireplace can accommodate an insert. The most important factor to consider is the size of the fireplace opening. The insert must be able to fit inside the opening, leaving enough space around the edges for proper ventilation.

Here are some additional factors to consider when assessing your fireplace:

Firebox size: Measure the height, width, and depth of the firebox to ensure the insert will fit comfortably.
Fireplace throat: The throat is the opening between the firebox and the chimney. It needs to be large enough to accommodate the insert's flue pipe.
Chimney size: The chimney needs to be large enough to handle the increased heat output from the insert. It’s a good idea to have your chimney inspected by a professional to ensure it’s in good condition.
Fireplace materials: Some fireplace designs may require specialized installation techniques or modifications to accommodate an insert.

If you're unsure about the compatibility of your fireplace, it's best to consult with a professional installer. They can assess the situation and provide you with expert advice.

Choosing the Right Insert

Once you've determined that your fireplace is compatible with an insert, you'll need to choose the right one for your needs. There are many different types of fireplace inserts available on the market, each with its own unique features and benefits.

Here are some of the most common types of fireplace inserts:

Wood-burning inserts: These are the most traditional type of fireplace insert. They offer a classic look and feel, as well as the ability to burn a variety of woods.
Gas inserts: Gas inserts are a convenient option because they don't require wood. They can be easily controlled with a remote or thermostat, and they produce a beautiful, dancing flame. Gas inserts also offer a high level of efficiency.
Pellet inserts: Pellet inserts burn wood pellets, which are a renewable and efficient fuel source. They typically have a high heat output and can be programmed to operate automatically.

When choosing a fireplace insert, it's important to consider the following factors:

Heating capacity: The heating capacity of the insert should be sufficient to heat the space you want to warm. This will depend on the size of your home and the level of insulation.
Efficiency: Look for an insert with a high efficiency rating. This will ensure that you're getting the most heat from the fuel you burn.
Features: Some inserts come with features like blower fans, remote controls, and programmable thermostats. These can make the insert more convenient and efficient to use.
Style: Choose an insert style that complements the design of your home. There are a wide variety of styles available, from traditional to modern.

Installing The Insert

Once you've chosen the right fireplace insert, it's time to install it. This is a complex process that should be done by a qualified professional. Never attempt to install a fireplace insert yourself unless you have the proper training and experience.

Here are the general steps involved in installing a fireplace insert:

Prepare the fireplace opening: The existing fireplace opening needs to be cleaned and prepared to receive the insert. This may involve removing existing brick or stonework, or adding additional framing or supports.
Install the insert: The insert is carefully placed into the fireplace opening and secured in place.
Connect the flue pipe: The flue pipe must be properly connected to the insert and the chimney. This is a critical step to ensure safe and efficient operation of the insert.
Connect the gas or electrical supply: If you're installing a gas or pellet insert, you'll need to connect the gas or electrical supply.
Test the insert: Once the installation is complete, the insert should be tested to ensure it's functioning properly. This includes making sure that the flue pipe is drawing properly and that the insert is heating evenly.

Installing a fireplace insert is not a simple DIY project. It requires specialized knowledge and skills. It’s important to hire a qualified professional to ensure the insert is installed correctly and safely. A properly installed fireplace insert will provide you with many years of warmth and enjoyment.
