Buying Guide: Best Gas Fireplace Inserts

Heating efficiency and Capacity: A fireplace insert should be both efficient and pleasing to the eye of the user. It will be a sheer wastage of money to invest in an electric heater only for the ambiance; it should warm up the place also. The output capacity of a fireplace is measured in BTU every hour. Every device can create a variable efficiency and maximum output. You can measure the efficiency of the machine by calculating the total amount of fuel that is transformed into heat and how much is lost in the process.

Coverage: The heat produced by the gas fireplace inserts can warm up large coverage spaces like cabins, floors, or even the entire home. Most of the models can generate 15000 BTU per hour even if they are operating at the lowest level. However, you should also keep in mind about the insulation of the house and the climate of the region to determine the coverage space. Below are the ideal areas that a fireplace should cover in a home with cold freezing weather.

15000 BTU- up to 300 sq. feet

25000 BTU- up to 500 sq. feet

40000 BTU- up to 800 sq. feet

Types of Fireplaces: We have divided gas fireplaces into the below types.

Built-in: Built-in fireplaces are the most popular ones that people always search for whenever they are constructing or renovating their homes. These bulky, heavier, difficult to manage and set up fireplaces, offer unbelievable heating output and efficiency. They appear like inserts but come inside a metallic box.

Inserts: Inserts can be installed in place of old fireplaces. This device does not consume much space and is exceptionally efficient in producing heat. However, you should first measure the old fireplace before buying an insert. Otherwise, you will require redesigning the entire space to fit the insert.

Self-standing: The self-standing devices do not require a hole in the wall for the setup. You need to assemble the entire unit and connect it to liquid propane or natural gas. The entire installation process is hassle free and easy to operate.

Variable Control of Flame: Variable control of flame allows you to manage the heating output and the power of the fire. The bigger the flame, the higher will be the heating output and vice versa. This feature also permits the user to enjoy a dance even in the summer season by turning off the heating option and only use the flames for creating a beautiful ambiance. You also need to take care of the thermostat control to maintain a specific temperature throughout the entire day. You can regulate the temperature, along with controlling the dancing of the flame.

Installation: Most of us think that a new fireplace means ripping out the structure and redesigning everything from the start. But you can ignore all the fussiness by installing gas fireplace inserts. The only problem you can have in setting up this device is that you selected a vented model and does not include an existing chimney or a flue. Vent-free inserts are much easier to carry or push into a place, attaching a gas line up, plugging it inside, and then lighting it up. But if you are not confident enough about how to install the device, then we would recommend asking for the professional help from the company.

Safety Features: Would not it be great if you can enjoy the cracking heat with no worry of any spark escaping the fireplace and putting something on fire? Well, gas fireplace inserts burn completely clean with no requirement for a chimney or a vent. Many models come with sensors for Oxygen depletion that turns off the machine in case of low oxygen or excessive carbon monoxide level. Some heaters even come with overload protection that also cut off the unit from the power supply once it reaches the maximum temperature. The cool to touch feature of the inserts ensures that no one gets hurt while it is operating in the background.

Each of the products reviewed in this write up comes with numerous features. So choose your gas fireplace inserts wisely after considering all the advantages and disadvantages of every model.
