We like how much warmth this modern fireplace puts into our home, and how quickly it removes the chill even in the middle of winter. We would have rated it higher if had included a blower.

In terms of the heat produced it was one of the best gas fireplace inserts. At dimensions of 35 inches wide, 25.6 inches high and 17.5 inches deep it quickly heated up my home. But because it doesn’t come with any extras, the total cost is a bit higher if you add on all the accessories.

There are aspects of this modern gas fireplace insert which I have found to be useful, namely the oxygen depletion sensor and the Piezo ignition function. Even though this has the oxygen depletion sensor, I recommend still making sure your carbon monoxide sensors work in case the sensor fails. Like other fireplaces on this list, the blower is extra. I found that money can be saved by lowering the thermostat controls.

In terms of BTU output alone it is among the powerful fireplace inserts we have used. Ideal for filling a larger fireplace.

What is the best gas fireplace insert?

Once we completed our reviews of all the inserts we agreed that the Duluth Forge Dual Fuel vent insert was the best gas fireplace insert. It was the most economical to run and included a blower

What is the difference between a gas fireplace and a gas insert?

A gas fireplace usually means the fireplace was originally installed with the home, whereas a gas insert has replaced the original fireplace, whether that was wood, coal, or a previous gas insert. 

How much is a gas fireplace insert?

Depending on the exact specifications and features, a gas insert will cost in the region of $600. Some inserts may cost less but you might have to pay extra for accessories that more expensive ones include in the higher price. 

Are gas fireplace inserts worth it?

Generally gas fireplace inserts are worth the money, though some models are more efficient or better performing than others. It is always best to check what accessories come included with the inserts, and which ones have to be brought separately. 

Do gas fireplaces need to be vented?

This depends on whether the existing fireplace was previously vented, and also some inserts do need to be vented and others do not. The description and the instructions with specific models will state whether or not venting is required. If vent fireplace is not required we recommend that you have a window cracked to help reduce carbon monoxide gases that may be about.

How much does it cost to convert fireplace to gas?

It will cost the price of the insert you buy, plus it may cost additional for accessories or if new pipes and connections are required. There may be extra costs if you need to pay a gas engineer to fit new or extra pipes. 

Which is better gas or wood fireplace?

That comes down to personal preference. However there are benefits to using gas instead of wood, for instance, there is no smoke, no ashes and no need to buy and cut wood. With gas, there is no need to store wood and it is easier to control how much heat is produced. 

Can you put real wood in a gas fireplace?

The quick answer to that is no. It would not be safe to do so. Basically if there had previously been a wood-burning fire, you would have to remove the gas insert and convert it back. Then it would have to pass a safety check before you could use it.

Do fireplace inserts really work? 

Yes fireplace inserts do work, providing that all of the pipes and connections are fitted properly.
