Deciding Factors in Fireplace Inserts

Fireplace inserts come in all shapes and sizes, but here are the things you should consider before investing in a fireplace insert:

1. Type of Fireplace Insert

There is a growing preference for electric inserts over other types of inserts, but some people still prefer traditional types of fireplace inserts such as wood, gas, or pellet inserts for various reasons. If you prefer non-electric fireplace inserts, you need to reconsider your surroundings and gauge the space you have for your home and fireplace to estimate the right fit for your fireplace insert.

If you don’t have enough supporting materials to withstand the heat of a wood insert, a wood insert could potentially set your house on fire, so it’s better to forgo that option.

Electric inserts eliminate most problems proposed by traditional inserts, but there are pros and cons to each type, as the wood insert could keep your home warm in case of blackouts, as it does not rely on electricity.

2. Size and Dimension of the Fireplace Insert

This concept is an extension of what we’ve discussed above, but it’s vital to consider the size and dimensions of a fireplace insert, to be sure the insert provides the right amount of heat for the size of the space. If an insert doesn’t provide enough heat output for your room, you won’t be able to feel the heat, and if it provides too much, your room may become too hot. Either way, getting the right amount of heat output is vital for ensuring a comfortable temperature.

To achieve this, you should at least measure the depth, width, and height of your fireplace to ensure a correct fit. Even as modern day inserts are designed with various room sizes in mind, it doesn’t guarantee a good fit, especially concerning aesthetics. Manually checking the dimensions can prevent such issues.

3. Venting

Venting tends to differ for different types of inserts, but it’s vital to have a good venting system in place if you are using traditional fireplace inserts, as it would be very hard to manage without proper venting. Without correct ventilation, it would eventually become impossible to keep the fire going and your insert may stop working.

Electric fireplace inserts eliminate venting issues, as electric inserts don’t require any venting under any circumstance.

Reviews of the Best Fireplace Inserts

Inserts are a viable option if you want to improve the features and appearance of your existing fireplace, or if you have a chimney or a hole big enough to fit it and want the insert for decorative purpose.

What is the Difference Between a Fireplace and a Fireplace Insert?

Basically, a fireplace is the structure that you burn wood inside of. It could either be a factory-built metal style or even a brick-and-mortar structure. Meanwhile, an insert, as the name might suggest, is either a gas or wood stove that is to be inserted in an already-present fireplace.

How Do You Measure for a Fireplace Insert?

To measure for a fireplace insert, you must take into account your existing fireplace and the opening it has. For the best fit, you’ll have to measure the opening height, width, and depth. The depth should be measured from both the bottom and top. In addition, also measure the rear width as well as the depth of the area present in front of your fireplace.

Are Fireplace Inserts Safe?

Some elements of the insert can become excessively hot to touch. However, today, many of these are created with ‘Safe Touch’ technologies to keep the insert’s surfaces at low temperatures. In addition, inserts produce less smoke and promise cleaner burning of fuel.

Can You Put a Fireplace Insert in a Manufactured Fireplace?

A fireplace insert goes directly into a masonry fireplace that already exists in your house. Therefore, by connecting to the chimney as well as the flue that leads outside, the insert will take the place of the fireplace.

Can You Burn Wood in a Fireplace Insert?

The purpose of inserts is to replace inefficient wood fireplaces and introduce new appliances inside of them that promise cleaner burning. So, it is totally possible to burn wood in an insert.
