How to Choose a Gas Fireplace

Determine the type of fireplace that will fit in your home. The two main types of gas fireplaces include freestanding and built-in. Freestanding gas fireplaces are typically lightweight and provide flexibility in where they can be installed. Built-in fireplaces are built directly into the wall and closely resemble traditional wood-burning varieties. Both types of gas fireplaces use gas logs instead of wood, reducing the risk of house fire and eliminating the need for heavy cleaning and maintenance.

Review the fuel options for the fireplace. The two most common sources of energy for a gas fireplace are propane and natural gas. If you currently have a natural gas supply fueling your kitchen stove, then this may be the most cost-effective option. While propane features the same energy efficiency as natural gas, you must install a propane tank outside your home to store it. If you're unable to access natural gas or if getting to it requires extensive modification, a propane fireplace may be better.

Determine how you want the fireplace to vent. Like traditional fireplaces, most gas models require some form of air venting. The most common is direct venting, which requires a flute to ventilate air. If you want to avoid installing a vent flute, you may prefer a ventless gas fireplace. This version vents the air directly into the room, thus you don't have to create a hole for a flute.

Choose a fireplace dealer with a solid reputation. When reviewing dealers, ask not only for the price of the unit, but also the price for installation and whether they service the fireplace. If they don't provide installation or service, make sure they are able to arrange for a professional to perform the work.
