How Big Should Your Gas Fireplace Be?

Well, folks, here we are again. Summer has come and gone and winter is upon us. It's officially Gas Fireplace Season and you're wondering what type or size of fireplace you should install into your home. We get people coming in all the time looking to buy a gas fireplace and their eyes are immediately drawn to the largest one (naturally). Similar to the saying "my eyes were bigger than my stomach," you're often best suited for a different sized fireplace to what you originally thought.

There are a few points to consider when you're picking a Gas Fireplace or Gas Insert. The main one being the size of the area you want to heat. If you're looking to heat a small room and you put a large unit in, you'll have a sauna even at the lowest setting. Vice versa for a large room: if you put a small unit in a large area, you won't get the full effect of the fireplace.

Another thing to consider with gas fireplaces is when they're installed, they're like an iceberg. What we mean by that is you really only see a small portion of the unit. Behind that wall is a large unit that goes 2, 3, even 4 feet back. So, if you've got a 10' x 10' room, you're going to be losing a few feet just to build your new mantle over a large unit.

When picking a fireplace, we can look to use the following baseline when we considering size and square footage.

  • Small Gas Fireplace: less than 500 sq. ft.
  • Medium Gas Fireplace: 500 - 1,000 sq. ft.
  • Large Gas Fireplace: 1,000 - 2,000 sq. ft.
  • Extra-Large Gas Fireplace: 2,000+ sq. ft.

Remember this is just a baseline and this can change depending on things such as: ceiling height, room layout, insulation, electronics, and so on. Heat has to travel, so if it's going up high ceilings or has to go around walls, you're going to need a higher BTU output.

Now you're probably wondering, what constitutes a small fireplace from a large fireplace? The main contributor to that is BTU output. BTUs are the measurement for heating appliances and the definition is: 1 BTU is the energy needed to heat or cool one pound of water 1 degree Fahrenheit at sea level. To simplify, more BTUs = more heat! 

To apply BTUs to the sizes we listed above, we get the following chart:

  • Small Gas Fireplace:  12 000 - 15 000 BTUs
  • Medium Gas Fireplace 15 000 - 25 000 BTUs
  • Large Gas Fireplace: 25 000 - 35 000 BTUs
  • Extra-Large Gas Fireplace 35 000 + BTUs 

If you want to get an idea of a few different fireplace options, we've outlined a few different units below of different sized gas inserts, fireplaces, and linear fireplaces.
