How Efficient Are Gas Fireplace Inserts?

Gas fireplace inserts are a popular way to add warmth and ambiance to a home. But how efficient are they? Here's a look at some of the factors that affect the efficiency of gas fireplace inserts.

Efficiency Ratings

Gas fireplace inserts are rated for efficiency by the Annual Fuel Utilization Efficiency (AFUE) rating. AFUE ratings range from 0% to 100%, with higher numbers indicating higher efficiency. Most gas fireplace inserts have AFUE ratings between 60% and 80%, which means they convert 60-80% of the fuel they burn into heat.

Types of Inserts

There are two main types of gas fireplace inserts: vented and ventless. Vented inserts require a chimney or other type of venting system to exhaust combustion gases outdoors. Ventless inserts do not require venting, but they are less efficient than vented inserts because some of the heat produced is lost to the room air.

Installation

The efficiency of a gas fireplace insert can also be affected by the installation. A properly installed insert will seal tightly against the fireplace opening, preventing heat from escaping. A poorly installed insert can allow heat to escape, reducing the overall efficiency of the insert.

Burner Technology

The type of burner technology used in a gas fireplace insert can also affect efficiency. Some inserts use traditional burner technology, while others use advanced burner technology that can improve combustion efficiency. Advanced burner technology can help to reduce fuel consumption and increase heat output.
