The Advantages of Gas Fireplace Inserts

If high utility bills are inspiring you to find supplemental gas-fueled heat sources, you may not need to look any further than your existing masonry fireplace. A gas fireplace insert will convert your inefficient fireplace into a viable heat supply that can help you significantly reduce energy costs. There are various factors that affect the level of benefit you realize from adding a gas fireplace insert. Those factors include the R-value of your insulation, how high your ceilings are, and the climate where you live. In all circumstances, however, you will realize great benefits from a gas insert.

Serious Heat

Have a gas insert installed in your masonry fireplace or prefab fireplace and you will enjoy a new source of serious heat. At least 70% and possibly much more of the heat from your gas fireplace insert will warm your home. Compare this to the dismal efficiency rating of a masonry fireplace, which is usually 10% efficient at the most.
The amount of heat output from a gas fireplace varies widely. Our professionals at Marsh’s Stoves & Fireplaces will help you determine the number of Btus that would be perfect for your home in winter. The possibilities range from 7,000 to 60,000 Btus.

What is a Gas Fireplace Insert?

The first step in having a gas fireplace insert installed in your home is to get the requested measurements from the masonry or prefab fireplace it will be inserted into. A log-and-burner set is inside a metal box and then surrounded by a larger metal box that fits into the existing fireplace. Radiant heat is created as warm air in the gap between the boxes radiates from the firebox. Part of the installation process involves holes being drilled for gas and electrical lines. A gas fireplace insert can be vented with a fixed glass panel you can watch the flames through or it can be vent-free with a glass panel or fixed metal screen.

Unmatched Convenience

When you have a gas fireplace insert, you have the wonderful benefit of incredible convenience. Start enjoying the warmth and pleasant flames with the flip of a switch or the turn of a knob. When you compare this to a wood-burning fireplace, you have the right perspective on why so many busy homeowners choose gas.
The convenience of a gas fireplace insert doesn’t stop with the fact that you don’t need to chop, split, haul, and stack logs. You also don’t need to continuously tend the fire while trying to make sure embers don’t escape the fireplace. The fire will continue burning as desired and won’t go out as a result of neglect.


You have several choices when switching to a gas fireplace insert. You can use natural gas or propane. You can have any of the following features and more:
· A wall thermostat control;
· Electronic ignition, which eliminates the need for a pilot light and can mean a monthly cost savings of up to $10;
· Built-in fan, which pulls indoor air into the space behind the firebox and then pumps out hot air; and
· LED accent lighting, which adds another dimension to the realistic logs and fire.
