In today’s world, people want everything ready-made. Though they do enjoy the non-digital things, they don’t want any hassle if doing that. One of the products in this area is the fireplace. 

Installing a wood-burning fireplace is quite a hassle. So there are many fireplaces in the market which can provide you the feeling of having a traditional fireplace. One of the most popular among them is the gas fireplace.

In the gas fireplace, Gas is entered inside the metal box of the fireplace. This box is inside a bigger-sized box. These two boxes are used for heat generation. After this, heat is transferred from the fireplace. 

But in some cases, gas fireplaces can’t create enough heat in the room. In this case, you can feel chilly despite having the fireplace. We will explain the reasons and solutions to how to get more heat from a gas fireplace in this article.

The Reasons for Not Getting Enough Heat

There are several reasons your fireplace doesn’t create warmth in your room. The reasons why you don’t get proper heat could be the followings:

Heat Performance:

BTU measures the heat capacity of a fireplace. It is a rating system for measuring heat. Sometimes the BTU passing for the fireplace is not enough to create heat in your room. Your room may be big for the BTU range. 

For example, 4000 BTU can provide you with proper heat for a 1000 sq ft room. So if you choose any fireplace under 4000 BTU for a 1000 sq ft space it will lack efficiency for sure. 

Low Thermostat:

The thermostat generally controls the temperature of a device. You can increase the temperature or decrease it by using the thermostat. 

Sometimes you don’t notice the thermostat of your gas fireplace is kept low. When you don’t feel proper warmth in your room, that can be one of the reasons for not getting enough heat.

Poor Ventilation:

The house’s ventilation system can be a reason for not getting proper heat. If it has bad ventilation the cold air will come into the room frequently.  

Because of this, the heat cannot pass throughout the room efficiently. Also, too much cold air from the outside can lower the heat. 

Inappropriate Gas Fireplace:

Your purchased gas fireplace may not be suitable for your home. The specifications of the fireplace may not be enough to create heat in your room. 

For example, some gas fireplaces don’t create a strong flame or enough heat to make you feel comfortable in the cold.

Poor Flame:

Flames pass heat to create warmth. But some flames don’t stay lit all the time. It can be because of the log or anything. Generally, the flame needs logs that can support it to stay lit. 

Also, fuels play a major role to lighten up the bright flame. So because of unlit flames, sufficient heat cannot be created.

Methods to get proper heat from gas fireplace

Owning a gas fireplace without getting proper enough heat is a kind of a waste of money. So we should give some effort to this matter. 

You can check several factors and strategies you can follow to get sufficient heat. Let’s jump into the details.

Regulate the thermostat:

You should check the thermostat of your fireplace. If it is turned down, it should be set at the highest temperature to get the maximum heat.

Keeping a Blower:

Blowers are used to flowing the heat all over a place evenly. It is a type of electric fan. It doesn’t generate any heat itself but they are useful to provide heat to every corner of the room.

Check the Damper

The damper is helpful for heat efficiency. If you install it inside your chimney, the heat will not fade away from the room easily. But you should be careful in using a damper. 

If the damper is very wide, the heat can escape. For that, the room will not be heated. So be sure of having the perfect sized one.

Installing a Fireback

Firebacks are sheets made of steel or iron. It is generally used for heat efficiency. The fireback is placed behind the flames of fire. That reflects the heat that tends to escape from the room. So it is great for keeping your room warm.

Checking the Insulation

The insulation system should be checked when your room doesn’t get hot. Sometimes, the heat fades away if the fireplace is placed on a wet wall. Also, without a vapor barrier, the heat goes away immediately. 

Clean the Fireplace

Always keep your fireplace neat and clean. The dirty fireplace cannot transfer heat properly. So you should regularly check the fireplace and clean it regularly.

Improvising your own device might allow you to save money on a heat exchanger. An old fireplace, spare parts, and scrap metal will allow you to increase the efficiency of your fireplace.
