  • How Much Heat Does A Gas Fireplace Put Out

Before heading over to the point directly, let’s first discover why doesn’t your gas fireplace put out heat efficiently. So, let’s get started right here. 

Why Your Gas Fireplaces Won’t Heat The Room

Why Your Gas Fireplaces Won’t Heat The Room

Your gas fireplace won’t heat your entire room if you choose the wrong type of gas fireplace, your room is not well-insulated, and the unit is not functioning properly. Therefore, the following reasons are responsible for not getting sufficient heat output from a gas fireplace. 

  • The BTU rating of your gas fireplace is insufficient for heating your home.
  • Most of the heat may go out of the flue. 
  • You may have a decorative gas fireplace or a fireplace that’s not perfect for your situation. 
  • Air circulation is not good. 
  • The shape of your home makes it challenging for the fireplace to distribute heat evenly throughout your home. 
  • You may set the thermostat too low. 
  • The flame won’t stay lit. 

How To Get More Heat From Gas Fireplace [7 Simple Ways]

You already know why your gas fireplace doesn’t deliver sufficient heat to boil the frigid condition of your room. Now, it’s time to know how to maximize the heat output of your gas fireplace. 

1. Check Out The Dampers 

A damper is a type of metal plate that is placed in your chimney. It is used to regulate airflow. 

Inspect the damper of your gas fireplace and ensure you install it either inside the chimney or mounted to the chimney cap. Installing the damper in either of these places will reduce heat loss. 

However, make sure you don’t keep the damper opened too wide. If the damper is open, it allows the hot air to travel up to the flue and draw out. At the same time, it lets the cool outside air draw inside the room. 

Consequently, heat loss will happen, and you don’t get the desired heat to warm your room. To get rid of this issue, make sure your damper remains slightly open. 

2. Get A Fireback For Your Gas Fireplace

Secondly, you can install an iron plate or a fireback into your gas fireplace. Open fires from your gas fireplace insert are unable to flow heat into your room. Most of the heat escapes through the chimney. Installing a fireback will absorb that heat and reflect it into your room, which will maximize the efficiency of your gas fireplace.

3. Get A Fireplace Blower

Don’t install a blower into your gas fireplace? Then, grab it from your local store and place it inside of your firebox. The blower pulls your room air and forces it to travel through a channel of the fireplace’s exterior. As the air moves around your hot fireplace, the surrounding air gets hot, and it releases into your room.  

In simple words, a blower pulls the air from your room, warms it up, and distributes the warm air throughout your room evenly. In return, your freezy interior environment turns into spring and provides you with the ambience. 

Plus, if you discover your fireplace mantel gets hot, the blower will also help to keep the mantel cool. Here we recommend you to get the blower from where you purchase the burner insert. 

4. Maintain The Fireplace Blower

We already told you how a blower increases the efficiency of your gas fireplace. But if you leave it for months and don’t clean it, dust & dirt make the blower their home.

As a result, your blower starts losing its ability to distribute hot air, which also decreases your gas fireplace efficiency. That’s why we recommend you inspect the blower every six months and clean it. 

5. Invest In A Fireplace Heat Exchanger

You can also spend your money on having a heat exchanger to boost up the efficiency of your gas fireplace. The heat exchanger will draw the heat generated by the gas fireplace and distribute the warm air into your room with the help of a fan blower. 

6. Set The Thermostat To The High Position

Maybe you set the thermostat too low, which gives insufficient heat output to warm your room evenly. First off, check the thermostat to see its position. If you set it too low, turn it to the high position to get more heat from your gas fireplace. 

You can turn the thermostat dial-up to 90°F to maximize the heat output. But remember, setting the thermostat to a higher position will not be friendly to your wallet as it will trigger the electricity bill. 

7. Choose The Correct Type Of Gas Fireplace

All of the tips we mentioned above will go in vain if you have the wrong type of gas fireplace. You know two kinds of gas fireboxes are pretty popular- direct vent and vent-free. 

Among them, direct-vent is the most efficient, and there occurs a minimum heat loss. It uses outside air for combustion. This means cold outside air can’t come into your room through windows or doors. As a result, no heat loss will happen & interior air remains warm which makes the room friendly in ice-cold conditions. 

Does A Gas Fireplace Actually Heat A Room

Most gas fireplaces (whether it’s vented or ventless) can evenly heat your room due to their higher efficiency. Indeed, vented or ventless gas fireplaces are designed to produce heat and allow you to warm your room thoroughly. On the other hand, decorative gas fireplaces don’t generate enough heat to make an entire space equally warm. 

Indeed, what type of gas fireplace you have will determine whether it can heat an entire room efficiently or not. 

For example, you can feel the warmth or heat if you sit directly in front of the decorative gas fireplace. In contrast, you can’t get the heat if you go to the corner of the same room. It’s because the decorative gas log set uses the chimney for ventilation. In other words, all the heat it generates goes up via the chimney, instead of distributing the heat around your room. 

On the other hand, vented or ventless gas fireplaces are designed to generate heat and are self-contained. It means they don’t use chimneys like the decorative gas fireplace. So, there is no way for the heat to go outside of your room. In short, they can heat your room optimally as they release the heat directly into the room. 

Keep in mind that a ventless gas fireplace is more efficient than a vented fireplace. A vented fireplace has a flue that allows the by-products as well as the heat to go out. Indeed, you will lose heat. However, it can warm every corner of your home despite losing some amount of heat.

In contrast, a ventless one doesn’t require a chimney. As a result, no heat loss will occur. However, it will release fumes into the air. So, it is better to open the window if you use it for an extended time and make sure the carbon detector is working properly. 

BTUs rating of the gas fireplace also determines how optimally it can warm a fireplace. So, while picking your gas fireplace, it’s wise to know how many BTUs you need in your fireplace to heat your room perfectly.

However, it will be better if the fireplace is fan-forced. The fan inside the unit will distribute the heat evenly to warm every corner of your room.   

Therefore, how insulated your room is will also determine the heating ability of your gas fireplace. The gas fireplace will struggle to heat your room if your room is not well insulated as the inside will remain colder. 

In short, multiple factors come into play to determine whether a gas fireplace can heat the entire room or not. We recommend you use a regular gas fireplace instead of the decorative one. Also, make sure your room is well insulated. Lastly, use a gas fireplace with a large BTU rating if there are walls or doorways in the room. 

Can A Gas Fireplace Be Used As A Primary Heat Source

No, a gas fireplace can’t be used as a primary heat source due to its inability to offer sufficient coverage across your entire house. If you have a multi-level home, the gas fireplace fails to warm other floors of your home. So, we recommend using a central furnace to keep your entire property warm. 

However, you can use the gas fireplace as a central furnace to zone heat your home. It’s a heating system that focuses on only a few areas of your home to heat instead of warming the areas that are barely used. 

Therefore, some gas fireplaces are rated as primary heat sources. The efficiency of them is in the 85%+ range though AFUE numbers will indicate lower. You may use them as your central heating source. But, still, the heat coming out from the fireplace would have to travel long distances. So, it’s not efficient enough to heat every room of your home. 

Of course, you can practice zone heating and use the gas fireplace as a central heat source to cut down utility bills. 

Keep in mind; you can’t use all gas fireplace types as your primary heat source. For example, a decorative gas fireplace can hardly warm an entire room evenly, let alone the entire house. 

Technically, unvented gas fireplaces are more efficient than other fireplace types in heating a room. Because all the heat it produces stays in the room. But, it’s not safe for continuous use as it creates by-products and affects the indoor air quality. 

Indeed, it’s not practical to use gas fireplaces as your primary heat source. However, you can use them to practice zone heating and warm specific rooms evenly. 

How Much Heat Does A Gas Fireplace Put Out

Typically, gas fireplaces can generate between 5000-50000 BTUs of heat output, depending on their models. However, the average heat output you will get from a gas fireplace is between 25000-30000 BTUs. 

Therefore, the size of a gas fireplace also affects the heat output. For example, a small gas fireplace can produce up to 20000 BTUs of heat output. On the other hand, a medium gas fireplace unit delivers up to 30000 BTUs. 

Lastly, a large gas fireplace can generate up to 50000 BTUs of heat output.

  1. My gas fire flames consistently discharge blue. I inspected the appliance and everything is functioning well. But then, what gives? Why are the flames not orange?

    • Hi Anthony

      You are getting a blue gas flame with a hydrocarbon gas when you have enough oxygen for complete combustion and create enough energy to excite and ionize the gas molecules in the flame. And orange, yellow and red flames tell there is incomplete combustion of the gas. The blue flames burn hotter than orange flames.

      Hope you could understand.

      Thanks
