The addition of a fireplace in homes has over time been seen as a decorative element as it is a focal point. However, as beautiful as a fireplace is, it also has practical functionality of warming up your home.

Unfortunately, a wood-burning fireplace does little in the form of adding warmth in your home.

To ensure that a fireplace is practical, you need to choose an energy-efficient fireplace type.

Below is a practical guide to selecting an energy-efficient fireplace insert 

Efficiency Rating

To select an energy-efficient fireplace insert, the first thing you need to consider is the efficiency rating.

Unfortunately, wood stove efficiency is at the bottom of the peer as its percentage is low.

With only 15% of the wood energy converted to heat energy, a lot of it goes to waste. Fortunately, newer energy-efficient wood-burning fireplaces inserts have an efficiency rating of more than 75%. 

However, for the ultimate efficiency rating, consider investing in gas fireplaces as they are even more efficient. 

Heating Square Footage

To further make a fireplace insert energy efficient, the basic design takes into consideration the heating square footage.

Getting the correct heating square footage allows you to invest in the right sized fireplace insert. 

As a result, your fireplace isn’t falling shot on heating or overheating your residence.

To calculate the correct heating requirement to purchase the ideal gas, wood, or energy-efficient electric fireplace, multiply the square footage of your home with 20BTUs per square foot.

The dimplex dlgm29 is an excellent choice for an average 2500 square foot house as it gives you better control to send maximum heat back to the room.

Heating Time

Many people ideally yearn for the wood-burning fireplace element as it creates a great ambiance with crackling sounds, great smell, and glow.

However, when considering heating time, an open wood-burning fireplace has the slowest heating time as most of the energy is wasted before it turns to heat.

Fortunately, the gas fireplace is the most efficient heating fireplace option as it has the longest heating time followed by the electric fireplace.

When choosing, consider a well-constructed fireplace insert and that requires a few heating cycles and time for maximum heat. 


To ensure that you do not lose heat from an ill-constructed fireplace, ensure that you choose the correct sized fireplace.

This is especially important when considering a wood fireplace heat output as heat can escape through the chimney.

The critical factor when considering the size is the opening of the existing fireplace. Ensure that you measure the depth, width, and height of the fireplace.  

Fuel Use 

When considering whether to choose electric, wood vs. gas fireplace, something to consider apart from finding an energy-efficient fireplace is the manner it uses fuel.

Ideally, you want to select a fireplace that saves you fuel. By far the most efficient method of heating is using pellets fireplace insert.

However, the use of wood pellets is more expensive when compared to using wood, electricity, or gas.

Nonetheless, if you are living in an apartment, using electric or gas options are more practical than using wood or pellet.

For this reason, ensuring that the fireplace insert has the right kind of seal is essential. As expected, this ensures that less fuel is used hence saving you money. 


As seen above, choosing an energy-efficient fireplace is more than selecting a beautiful fire inset.

To ensure that a fire insert works for you, you need to consider your specific needs. Pay attention to the efficiency rating, the heating square footage, and the heating time.

Doing so will enable you to choose a fire insert that will save you money that would have otherwise been used on fuel.
