How to Measure for Fireplace Insert: A Comprehensive Guide

How to Measure for Fireplace Insert?

To measure for a fireplace insert, you will need accurate measurements of the old fireplace.

Measure the height, width, and depth of the fireplace opening using a high-quality measuring tape.

Write down the measurements to avoid mistakes.

Additionally, measure the size of the room where the fireplace insert will be installed to determine the correct BTUs needed.

The BTUs should be calculated by multiplying the room measurements by 20.

Taking proper measurements is crucial to ensure a proper fit for the fireplace insert.

Key Points:

  • Accurate measurements of the old fireplace are needed for measuring a fireplace insert.
  • Measure the height, width, and depth of the fireplace opening using a high-quality measuring tape.
  • Write down the measurements to avoid mistakes.
  • Measure the size of the room where the fireplace insert will be installed to determine the correct BTUs needed.
  • Calculate the BTUs needed by multiplying the room measurements by 20.
  • Proper measurements are crucial for ensuring a proper fit for the fireplace insert.

Did You Know?

1. Did you know that fireplace inserts are rated for efficiency based on their British Thermal Unit (BTU) output? The higher the BTU rating, the more heat the insert will produce.

2. While measuring for a fireplace insert, it’s important to consider the clearance requirements for both the insert and the surrounding combustible materials. The National Fire Protection Association (NFPA) advises leaving a minimum of 6 inches of clearance between the insert and any surrounding materials.

3. One little-known fact is that some fireplace inserts come with a self-cleaning feature called a pyrolytic coating. This coating burns off soot and reduces the need for manual cleaning, making maintenance easier for homeowners.

4. When measuring for a fireplace insert, remember to take into account the size of the firebox opening. The firebox is the area of the fireplace where the flames burn. It’s crucial to ensure that the insert will fit snugly within this space to optimize heating efficiency and prevent any gaps between the insert and the firebox.

5. Besides providing warmth, fireplace inserts can also offer additional benefits such as reducing energy costs. By using an insert, homeowners can reduce heat loss and make their fireplace more efficient, allowing them to rely less on other heating sources and potentially lower their heating bills.

1. Importance Of Accurate Measurements

Before purchasing a fireplace insert, it is crucial to obtain accurate measurements of the old fireplace. Failing to do so may result in an ill-fitting insert that could potentially compromise its functionality and safety. Accurate measurements are essential to ensure that the width, height, and depth of the fireplace opening align with the dimensions of the insert.

2. Measuring The Fireplace Opening

To measure the fireplace opening, it is recommended to use a high-quality measuring tape. Follow these steps to ensure accurate measurements:

  1. Start by measuring the height of the opening, starting from the hearth floor to the top of the opening.
  2. Next, measure the width of the opening from side to side.
  3. Lastly, measure the depth of the opening from the back to the front.

It is important to write down these measurements to avoid mistakes. Jotting them down ensures accuracy and precision.

When measuring, be mindful of any irregularities or protrusions within the fireplace opening. These factors may impact the installation process and influence the choice of insert.

Remember these key points:

  • Use a high-quality measuring tape.
  • Measure the height, width, and depth of the fireplace opening.
  • Write down the measurements to avoid errors.
  • Pay attention to any irregularities or protrusions in the opening.

3. Measuring The Room Size For BTUs

BTUs, or British Thermal Units, are a measure of the capacity of a fireplace insert to warm up a room based on its size. To determine the minimum required BTUs for your room, multiply the measurements of the room’s length, width, and height in feet. Then, multiply the resulting figure by 20.

By calculating the necessary BTUs accurately, you can ensure that the fireplace insert will effectively heat your room, providing a comfortable and cozy atmosphere.

4. Benefits Of Fireplace Inserts

Fireplace inserts offer numerous advantages over traditional fireplaces and stoves.

Firstly, they allow for updates to your existing fireplace without requiring significant structural changes or renovations. This flexibility makes them a cost-effective choice for homeowners who desire a new look or enhanced functionality.

Secondly, fireplace inserts offer more environmentally friendly fuel options. Electric fireplace inserts, for instance, eliminate the need for wood or gas, reducing carbon emissions and indoor air pollution. Similarly, gas fireplace inserts provide a cleaner and more efficient burning experience compared to wood-burning fireplaces.

Moreover, fireplace inserts enhance safety by reducing the risk of sparks or embers escaping the fireplace. They also incorporate features like tempered glass doors for added protection. Additionally, inserts are known for their improved combustion efficiency, ensuring fuel is burned more completely and minimizing the release of harmful gases.

5. Electric And Gas Fireplace Inserts

When considering fireplace inserts, there are two popular options to choose from: electric and gas inserts. Electric fireplace inserts have several advantages. Firstly, they are safer as they do not produce real flames, eliminating the risk of accidental fires. Secondly, they are easier to manage, often coming with remote controls for adjusting temperature and flame settings. Additionally, electric inserts require less maintenance compared to gas inserts. Lastly, they are generally more affordable, making them an accessible choice for homeowners.

Gas fireplace inserts, on the other hand, offer convenience and a higher heat capacity. They provide the beauty of a real fire while also increasing heating efficiency. Gas inserts are connected to a gas line, ensuring a constant and reliable fuel source. Moreover, with various design options available, gas fireplace inserts offer a customizable and efficient heating solution.

In conclusion, before buying a fireplace insert, accurate measurements of the old fireplace are essential. The height, width, and depth of the fireplace opening should be measured carefully using a reliable measuring tape. Additionally, measuring the room size is vital to determine the appropriate BTUs needed for heating. Benefits of fireplace inserts include:

  • Convenience
  • Improved safety
  • Energy efficiency

Both electric and gas inserts offer unique advantages, and it is important to choose a reputable brand for a quality product.
