As much as we love the beauty of the fireplace, its main purpose is to provide heat. Yet homeowners are trying to figure out how to get more heat from gas fireplaces. So the main aesthetic of a fireplace lies in its ability to provide heat rather than its beauty.

To improve the heat of your home, you need to increase the heat efficiency of the fireplace. Like most homeowners, you will agree that fireplace skills need to be improved. But not sure how much to increase, how much efficiency your fireplace has left, and what else you need to do.

You can never exceed the actual functionality of a fireplace. All you can do is increase its durability and maximize its efficiency. We’ll discuss this topic in detail in this article.

Gas Fireplace Heat Output

Gas fireplaces are one of the cleanest and most fancy fireplaces in the world of fireplaces. Its output and efficiency are great, average 77%. Its appeal in the world of heat is increasing day by day as there is no smoke or odors.

There are usually two types of gas fireplaces: vented and vent-free.


The safest, most effective venting method is a two-pipe system. This is known as a direct vent. Vent fireplaces have to use two-way vents to supply outside air for combustion. As a result, they are less efficient than vent-free fireplaces. These units are typically 70 to 85 percent efficient.

There is a pipe to carry an exhaust known as a B-vent. The flames get the combustion air from inside it, making them about 50 percent efficient as well.

About 99 percent of these units are efficient. They have no flu so they can be installed anywhere. You can also hang it on the wall like a flat-screen tv.

Due to concerns about air quality, indoor units are subtly protected from extra clean burns. Typically, their heat output is limited to 40,000 BTU. They also have an oxygen-depletion sensor that automatically shuts off if the oxygen level in a room drops below 18 percent. They don’t need any flue or chimney.

Inspect both your fireplace and your chimney at least once a year Although there will not be a vent-free fireplace chimney, the fireplace needs to be inspected by a skilled service technician in other contexts. These check-ups will protect you and your family, and help protect you from frequent repair bills.

How to Get More Heat From Gas Fireplace?

If you have a gas fireplace, you may be wondering how to get more heat from it. While gas fireplaces are designed to provide a certain level of heat, there are a few things you can do to increase the amount of heat that your fireplace produces.

One way to get more heat from your gas fireplace is to make sure that the flue is open. The flue is the metal shaft that runs up the center of the fireplace and allows the hot air to escape. If the flue is blocked, the hot air will have nowhere to go and will eventually build up, causing the fireplace to become less efficient.

Another way to get more heat from your gas fireplace is to add a fireback. A fireback is a piece of metal that is placed behind the fire grate. It reflects the heat back into the room, making the fireplace more efficient.

You can also get more heat from your gas fireplace by using fire starters. Fire starters are small pieces of wood or paper that you ignite and place under the logs in your fireplace. They help to get the fire going quickly and evenly, which in turn will produce more heat. Also-

1. Use the Right Gas Burner

Make sure you cover the gas burners properly. You should use silica sand on top of burners in natural gas logs and fire glass fireplaces and use vermiculite with propane gas fireplaces. If propane is used in silica sand in a fireplace, it can limit the amount of propane, which rises to the surface and reduces the size of the flames.

2. Choose the Right Size of Fireplace

A big fireplace doesn’t mean it’s good. It should be selected in coordination with your home. A 20,000 BTU gas fireplace is enough to heat a 900 to 1,200-square-foot home. If you can choose the right size for your fireplace, you will get more comfortable heat.

3. Burn to a Different Volume

It can be seen that many fireplace owners set the gas to the maximum setting whatever the temperature is and always keep it burning at that level. It does not balance the temperature with the weather. While the fireplace is burning, it sometimes feels cold and sometimes hot, although the flames look nice.

For this, you should adjust the flame of the fire remote or the gas dial near your igniter switch. This will make your home more comfortable, and create a more durable one.

4. Check the Gas Line

If applicable, inspect the gas line inside the fireplace that contains the burner connecting the gas line. It can be flexible lines. If so, make sure there are no kinks on the line. Kings can limit the size of the flame by reducing the amount of gas in the burners.

5. Check the Orifices

First, wipe the burners with a soft cloth. Examine the gas orifices. The vacuum area can be surrounded by thorns to remove any dust, cobs, or animal hair. Canned air has been used to clean up any debris from gas orifices that can ignite and prevent burns from burning.

6. Close the Damper

The current setup of your fireplace is not adding full heat to your home. Maybe the damper is open. When it is open a lot of air travels in the flue up that air is hot air from inside your house, which will be replaced by cool air coming from outside through the cracks in your house. You will lose the heat you deserve in this air.

7. Use Cast-iron Grate

You can place a heavy cast-iron grate in front of the fire. This will help your heat sink as well as limit some airflow to the fireplace. Drawing heat from the iron fire will more efficiently exchange heat with indoor air.

8. Replace a Tempered Glass

If you replace the tempered glass front with ceramic glass, this material will become stronger and more efficient in transmitting heat from the gas flame to the house.

9. Ensure Proper Insulation

Ensure that the gas fireplace insert is fully and properly insulated with a vapor barrier and drywall. This will help to prevent heat from being in the wall’s interior.

10. Maintain Your Blower

If you have a blower in your gas fireplace, it should be inspected at least annually every 6 months. These inspections will help remove buildup and dust, which can limit the blower’s ability to drive hot air.

How to Clean and Maintain the Gas Fireplace?

Proper cleaning and maintenance is the first thing you need to do to keep your fireplace or stove working effectively for a long time. Mainly, maintenance is essential for the longevity of your fireplace and its safe operation.

You should contact a licensed gas service provider for maintenance in your fireplace at least once a year. He or she will give you some advice by inspecting the fireplace to avoid potential risks even if you don’t find any immediate problems with your stove, which will help you secure your next year.

This is because a licensed gas inspector will inspect for venting, corrosion, excess condensation, proper fitting, and joint connections.

Remember, before working with a fireplace, you must make sure that it’s completely off including the pilot lights. When the fireplace cools down, work using eye protection and gloves. Be sure to keep your regency manual with you for any necessary instructions.

Follow the steps below to clean the fireplace properly-

First, open the glass door using the owner’s manual as a guideline. In this case, the doors of most gas fireplaces are made in such a way that anyone can easily open them to clean them.

Second, place the glass door on the floor below with old newsprint or your table or a large plastic bag. Now spray the window cleaner on a soft cloth and gently wipe it around with it. If there are any stains, you can use a small amount of fireplace cleanser or ceramic cook-top cleanser.

Third, replace the glass door. However, to prevent striking and to replace the door, wipe dry thoroughly with a paper towel or newsprint.

Fourth, give the fireplace 20-30 minutes before pilot lighting or starting the fireplace. This time the cleaner allows complete evaporation before coming in contact with the flame. Use clean gas logs.


How Much Heat Does a Gas Fireplace Generate?

A gas fireplace typically generates between 30,000 and 40,000 BTUs of heat, depending on the model.

How Does the Heat From a Gas Fireplace Compare to Other Heating Sources?

The heat output of a gas fireplace is generally comparable to that of a conventional furnace or boiler.

How Long Does the Heat From a Gas Fireplace Last?

The heat from a gas fireplace will last as long as the gas is burning. Once the gas is turned off, the heat will dissipate relatively quickly.
There are a few things you can do to maximize the heat from your gas fireplace: make sure the flue is open, keep the glass doors open, and do not block the airflow in any way.

Is There Any Way to Prevent Heat Loss From My Gas Fireplace?

There are a few ways to prevent heat loss from your gas fireplace: make sure the flue is closed when not in use, install glass doors, and/or install a heat-resistant barrier in front of the fireplace.


Proper use of this heat is no less important than how to get the most heat out of a fireplace. For this, heat-resistant coolant can be used around the fireplace. The door should be kept closed in the room where the fire is burning and the fireplace should be kept a beautiful focal point. 

However, by using the fireplace properly and knowing how to get more heat from the gas fireplace and get the maximum heat, it can truly become an asset to your home.
