Product Description: Heaters & Furnaces

At Fireplace Doors Online, we offer a wide range of heaters and furnaces to meet your home heating needs, including vent-free gas heaters, gravity vent furnaces, and B-vent furnaces. Each type of heating system has unique features, advantages, and considerations. Below, we provide detailed descriptions of each system, along with their pros and cons, and answer some frequently asked questions.

Vent-Free Gas Heaters

How They Work:
Vent-free gas heaters operate without the need for an external vent. They burn natural gas or propane and are designed to maximize heat output while minimizing emissions. These heaters use catalytic converters or oxygen depletion sensors to ensure safe indoor air quality.

Pros:

1. Ease of Installation: No venting required, making installation quick and easy.
2. High Efficiency: Nearly 100% efficient as all the heat produced stays in the room.
3. Portability: Can be installed in various locations within the home. No Bedroom or Bathroom, only if below 10,000 BTU's

Cons:

1. Air Quality: Must be used in well-ventilated areas to avoid issues with indoor air quality.
2. Regulations: Not allowed in all areas due to local building codes and regulations.
3. Moisture: This can produce moisture as a byproduct, which may lead to humidity issues.

Gravity Vent Furnaces

How They Work:
Gravity vent furnaces, also known as natural draft furnaces, rely on the natural buoyancy of hot air to vent combustion gases through a vertical chimney. These systems do not require a blower and rely on gravity to circulate warm air through the home.

Pros:

1. Reliability: Simple design with fewer moving parts, leading to less maintenance.
2. Quiet Operation: Operates without a blower, making it quieter than forced-air systems.
3. Energy Independence: Does not rely on electricity, which is beneficial during power outages.

Cons:

1. Efficiency: Generally less efficient than forced-air systems due to heat loss through the chimney.
2. Installation: Requires a vertical chimney, which may complicate installation in some homes.
3. Heat Distribution: May not evenly distribute heat throughout the home.

B-Vent Furnaces

How They Work:
B-vent furnaces, also known as natural draft or double-wall vent furnaces, use a double-wall pipe to vent combustion gases outside. These systems draw air from inside the home for combustion and expel gases through the B-vent pipe.

Pros:

1. Safety: The double-wall design reduces the risk of backdrafting and increases safety.
2. Efficiency: More efficient than gravity vent systems due to controlled venting.
3. Flexibility: Suitable for various home layouts and installations.

Cons:

1. Air Quality: Uses indoor air for combustion, which may affect indoor air quality.
2. Complexity: Installation is more complex compared to vent-free systems.
3. Heat Loss: Some heat is lost through the venting process.

Frequently Asked Questions About Ventfree Gas Heaters & B-Vent Gas Furnaces

Q: What is the difference between vent-free and vented heaters?
A: Vent-free heaters do not require external venting, while vented heaters use a chimney or vent pipe to expel combustion gases outside.

Q: Can I use a vent-free gas heater in any room?
A: Vent-free gas heaters should be used in well-ventilated rooms and may not be allowed in all areas due to local regulations.

Q: How often do I need to service my furnace?
A: It is recommended to have your furnace serviced annually to ensure safe and efficient operation.

Q: Are gravity vent furnaces energy efficient?
A: Gravity vent furnaces are generally less efficient than forced-air systems, but they offer reliability and quiet operation.

Q: What is a B-vent furnace?
A: A B-vent furnace uses a double-wall pipe to vent combustion gases outside, drawing indoor air for combustion.

Q: Do B-vent furnaces require electricity?
A: Some B-vent furnaces may require electricity for the blower, but gravity vent models do not.

Q: Can I install a gravity vent furnace myself?
A: Professional installation is recommended to ensure proper venting and compliance with local codes.

Q: What maintenance is required for a vent-free gas heater?
A: Regular cleaning and inspection of the catalytic converter or oxygen depletion sensor are necessary to maintain safety and efficiency.

Q: Is a permit required to install a furnace?
A: Permitting requirements vary by location, so it is essential to check with local authorities.

Q: How long do furnaces typically last?
A: With proper maintenance, furnaces can last 15-20 years or more.
