What Size Gas Fireplace Do You Need?

October 15, 2020

How to Find the Right Sized Gas Fireplace for Your Home

Typically, gas fireplaces are classified into four sizes – small, medium, large, and extra-large. As a basic benchmark, a small gas fireplace will heat less than 500 sq. ft., a medium gas fireplace will heat between 500 – 1,000 sq. ft, a large gas fireplace will heat between 1,000 – 2,200 sq. ft., and an extra-large gas fireplace will heat over 2,200+ sq. ft. These figures are based on an average size, single-story home in a moderate climate, and an open floor plan.

Pro Tip: Quickly measure the size of the space you are looking to heat to quickly and easily categorize the size of your fireplace needs by measuring the Length (L) and Width (W). L x W = Sq. Ft.

Standard Gas Fireplace Square Foot Heating Capacity

Small Gas Fireplace: less than 500 sq. ft.
Medium Gas Fireplace: 500 - 1,000 sq. ft.
Large Gas Fireplace: 1,000 - 2,200 sq. ft.
Extra-Large Gas Fireplace: 2,200+ sq. ft.

Note: this is simply a benchmark. A fireplace’s actual heating capacity will vary dramatically based on a high number of factors, see below for more details, and always discuss sizing and installation with an Authorized Regency dealer.

Factors Affecting Gas Fireplace Heating Capacity?

There is a wide variety of factors that can influence the heating capacity of your gas fireplace, insert or stove, some of these include:

Ceiling Height
- The total volume of the room can drastically change the heating capacity of a gas fireplace
Insulation
- Older poorly insulated homes will decrease the heating capacity of a fireplace, whereas new highly insulated homes may increase the capacity of the fireplace
Number of Windows
- Windows (even dual-pane) are a source of cooler air, and the more windows in a home/room, the greater the obstacle to the fireplaces heating capacity
Room/Wall Layout
- Open rooms vs. homes with lots of walls will affect how effective the fireplace is at heating an area
Other Vented Appliances
- Is there a hood vent in the same room as the fireplace? A dryer? Other appliances that require external venting can affect the draft and efficiency of your gas fireplace.
