What is a Gas Fireplace?

A gas fireplace is a type of fireplace that doesn't need wood to burn. Instead, it uses natural gas or propane to create flames. This makes it much easier to use than traditional wood-burning fireplaces.

How Do Gas Fireplaces Work?

When activated, gas flows into the burner of the fireplace. This gas is ignited by either an electronic ignition or a pilot light system. The intensity of the flame and the heat output can then be controlled using the model's adjustable settings. To distribute the warmth evenly throughout the room, a blower system circulates the heated air.

Natural Gas vs Propane Fireplaces

There are two types of fuel that you can use in gas fireplaces: natural gas and propane. Natural gas is a fossil fuel primarily composed of methane, allowing for efficient burning. However, since it is under normal atmospheric conditions, it has to be delivered using pipelines.

On the other hand, propane is a hydrocarbon that is a liquified form of petroleum gas. It is transported under pressure to maintain its liquid form, which allows it to be more portable than natural gas.

Feature	Natural Gas	Liquid Propane
Cost	Lower long-term cost	Higher fuel cost
Installation	High initial cost (if no gas line)	Easier and cheaper installation
Mobility	Limited to gas line access	Highly portable
Heat Output	Consistent	More efficient, higher output
Maintenance	Low maintenance	Requires regular tank refills
Environmental Impact	Clean burning	Clean burning
Safety	Dependent on gas supply	Requires careful storage and handling

Venting Systems

What’s the difference between a direct-vent and a B-vent?

Direct vents pull air from outside. They have a sealed combustion system that uses two vents to draw in outdoor air into one vent and then expel combustion gases in the other. This makes them safe and energy-efficient, as (1) they prevent warm indoor air from escaping and (2) the sealed chamber reduces carbon monoxide risks. In addition, direct vents can be installed anywhere. However, because of all these, direct vents cost more to implement.

B-vents use the air inside your home for combustion. They use a single pipe going through your roof to vent out gasses. Because of this, b-vents are less efficient due to heat loss. Additionally, backdrafting becomes a risk, so it requires proper installation and maintenance. Backdrafting occurs when combustion gasses from fireplaces, furnaces, burners, and other appliances flow back into the room instead of being vented outside.

B-vents also have limited placement options because they must be installed under a roofline and require a vertical vent pipe. On the bright side, they are cheaper to implement in homes.

Should I vent upwards or sideways?

The answer ultimately depends on the structure of your home. Check if your walls are built to vent upwards through the roof or sideways through the wall.

Different Types of Gas Fireplaces

Thus, opting for natural gas can provide both higher efficiency and a smaller environmental footprint.

Vent-Free Fireplaces

Vent-free (or ventless) gas fireplaces offer nearly 100% efficiency since all the heat generated stays within the room. However, they must be used with caution due to potential indoor air quality issues and are not permitted in some regions. These fireplaces are an excellent choice for maximum efficiency but require careful consideration of their placement and usage to ensure safety and comfort.

Modern Technological Features

Modern technological features such as programmable thermostats, remote controls, and smartphone apps enhance the efficiency of gas fireplaces. These features allow users to optimize heating schedules, reducing unnecessary energy consumption. By preventing overuse, these smart controls can improve overall efficiency by up to 10-20%. Additionally, some high-end models include modulating burners that adjust flame height and heat output based on the desired temperature, further enhancing efficiency and user comfort.

Regular Maintenance

Regular maintenance is crucial to ensuring that gas fireplaces operate at peak efficiency. Annual inspections and routine cleaning of burners and vents can improve efficiency by 5-15%, preventing energy waste and reducing emissions. Proper maintenance not only extends the life of the fireplace but also ensures it continues to provide efficient and reliable heating.

Safety Features

• Oxygen Depletion Sensor (ODS): This sensor is critical for automatically shutting off the gas supply if it detects a significant decrease in a room's oxygen levels. Since fireplaces consume oxygen during combustion, a drop in oxygen can lead to serious safety risks.

• Glass Fronts: These serve a dual purpose; they enhance the efficiency of gas fireplaces by retaining heat and acting as a safety barrier. The barrier prevents direct contact with the flame, and the glass stays cool enough to touch without causing burns, making it especially important in homes with young children or pets.

• Thermocouples and Thermopiles: These components are essential in detecting the heat from the pilot light and are designed to continuously monitor the presence of the pilot flame. If the pilot light is extinguished due to either a draft or a malfunction, these sensors will shut off the gas flow immediately to prevent the accumulation of unburned gas and avert potential hazards.

• Flame Failure Devices: These devices greatly enhance safety by stopping the gas flow if the flame goes out unexpectedly. This is crucial in ensuring that gas does not leak into the environment, thereby preventing potential fire and health hazards.

• Automatic Shutoff and Timer Features: Many gas fireplaces include automatic shutoff and timer features to prevent excessive operation. Users can set a timer to determine how long the fireplace runs, ensuring it does not stay on if accidentally left unattended, which also promotes energy conservation and enhances safety.

• Child Safety Locks: Included on some fireplace models, these locks are designed to prevent children from activating the fireplace or tampering with its controls. This safety feature is key in avoiding unintended ignitions or unauthorized adjustments to the fireplace settings by children.

• Ventilation Features: These are designed to ensure the proper expulsion of combustion gases and the intake of fresh air from outside. Effective ventilation is critical in preventing the buildup of toxic fumes inside the home. Most modern gas fireplaces come with direct venting capabilities to efficiently manage this exchange.

Regulations and Legal Codes

Gas fireplaces in the United States are subject to various national, state, and local regulations to ensure safety and compliance with building standards.

What Should You Consider?

There are a few things that you must consider before choosing a gas fireplace. This includes your budget, the purpose of the fireplace, preferred features, space restrictions, and design.

Budget

To avoid overspending, especially when income is tight, consider setting a price range you're comfortable with. Electric fireplaces come in a wide range of prices, heating capabilities, designs, and technologies. Long-term costs should also be factored into your budgeting since energy-efficient models may initially cost more but lead to monthly savings.

Purpose of the Fireplace

Ask yourself the following questions: What is my purpose in buying an electric fireplace? Do I want it to heat my room, or do I want it purely as room decor? By asking these questions, you’ll be able to pinpoint the exact model you will end up choosing. Additionally, assess your current living space: What is the size of your room? Does it have insulation? How many windows does it have?

Features and Safety

When selecting an electric fireplace, consider the features and safety aspects that are important to you. Look for models with adjustable heat settings, flame brightness control, and remote controls for convenience. Safety features such as automatic shut-off, cool-touch glass, and child safety locks are crucial, especially in homes with children or pets. Some models also include timers and thermostats for added control and energy efficiency. Ensuring the fireplace has built-in safety mechanisms will provide peace of mind and enhance the overall user experience.

Space Restrictions

Accurately measure the space where you intend to install the fireplace. If it's an insert, the dimensions of the existing brick-and-mortar will be crucial. For new installations, such as a zero clearance model, ensure the dimensions fit within your designated space without extensive modifications.

Aesthetic Preferences

If the primary function is to provide heat, opt for a model with higher BTUs, as more BTUs typically mean a larger fireplace. If aesthetics are your main concern, look for models with larger glass faces that offer clear views of the flames. Decide on the style of logs and the level of temperature control you desire, considering that some fireplaces offer remote controls, wall-mounted units, or both. Be mindful that some models have limited options regarding log appearance and may not be compatible with certain accessories or temperature control systems.

What You Should Do

Browse and Compare Models

Take the time to browse and compare different electric fireplace models. Look at various designs, features, and prices to find the best option that meets your needs and fits within your budget. Reading customer reviews and expert opinions can also provide valuable insights.

Purchase from Trusted Sellers

Ensure you purchase your electric fireplace from trusted sellers. Reputable retailers often provide better customer service, warranties, and return policies. They are also more likely to offer high-quality products from well-known brands.

Consult Installation Professionals

Consult with installation professionals to ensure your electric fireplace is installed correctly and safely. Professional installers can help you with any necessary modifications to your space and ensure that the fireplace meets all local building codes and safety standards.

Perform Regular Maintenance

Regular maintenance is essential to keep your electric fireplace functioning efficiently and safely. Follow the manufacturer's guidelines for cleaning and maintenance, such as dusting the unit, inspecting the wiring, and checking for any wear and tear.
