1 - General Questions

What is a 'vent-free' gas heating product?

Vent-free gas heaters, fireplaces, fireplace inserts, stoves and log sets are heating appliances designed to be installed and operated without a chimney, flu or vent. Vent-free products can be used with either natural gas or propane, and are intended to provide supplemental heat to a home. Because there is no vent, flue or chimney required, all of the heat generated by the product goes directly into the home. That's why vent-free products are 99.9 percent energy efficient.

What are the benefits of vent-free heating products?

Vent-free gas heaters, fireplaces, stoves and log sets offer homeowners a safe and energy efficient way to add heat to their homes. Vent-free gas appliances use precision burners and are design-certified by national testing laboratories to meet the latest national health and safety standards and guidelines.

What are some of the technological advances of today's vent-free appliances?

Many designs are available with hand-held or wall-mounted remote controls for lighting the unit and selecting the heat output. Most designs offer thermostatically controlled models that automatically modulate to maintain the selected comfort level/heat output.
Some models offer a timer device which automatically starts the appliance before the family rises in the morning or returns home in the afternoon.

How many vent-free products are in use today?

More than 17 million U.S. households use vent-free gas supplemental heating appliances. Vent-free products are fueled by natural gas or propane and their precision-engineered burners provide highly efficient, environmentally clean-burning heat.

Aren't there limited sizes and shapes for vent-free products?

Vent-free products come in every size, shape and color. Every year manufacturers introduce new colors and styles of vent-free products. Selecting a vent-free appliance is easy. It is recommended that you work with your local gas appliance or hearth retailer to find the best product to meet your needs.

How is a vent-free appliance different than vented products?

All vented gas and solid-fuel fireplaces lose some or most of their useable heat straight up the chimney or vent.
For example, vented gas logs installed in a wood burning fireplace typically burn 30,000 to 60,000 Btus/hour, and the fireplace damper must be totally open, resulting in most of the heat escaping up the chimney. Depending on the design chosen, a vent-free gas log in the same fireplace would burn only 26,000 to 40,000 Btus/hour, and virtually all of the heat produced would be delivered into the living space. Therefore, the savings in fuel costs with a vent-free gas log are tremendous, and the resulting comfort from the fireplace is dramatically increased versus a vented appliance or burning wood.

Can vent-free products be used as a home's sole heating source?

Vent-free gas appliances should be used as supplemental zone heaters and not as a primary source of heat, except during a power outage.

Can ceiling fans be installed in rooms with vent-free fireplaces? Is windows 10 still free to install.

Can ceiling fans be installed in rooms with vent-free fireplaces? Ceiling fans may be used to help distribute the heat, however, fans should not be allowed to blow directly into the fireplace to avoid any drafts that alter burner flame patterns, which can result in sooting.

Do vent-free products work when the power goes out?

Yes. Most vent-free appliances don't rely on electricity. They supply heat even when home power is lost due to severe weather or emergency situations.

2 - Efficiency

What are the most fuel efficient gas heating products on the market today?

Vent-free appliances are the most fuel-efficient gas heating products on the market today. All vent-free gas appliances are 99.9 percent efficient. Virtually all of the gas or propane burned by the product is converted into room-warming heat.

Isn't natural gas an expensive fuel option?

While prices of all fuels have risen in the past several years, natural gas still provides more heat for the dollar than any other home heating fuel. A direct comparison of costs for different fuel types based on 2006 U.S. Department of Energy (DOE) average unit costs of energy follow.

Doesn't it cost a lot to run a vent-free heater?

It costs pennies per hour to operate a vent-free gas supplemental heating appliance.
A typical vent-free fireplace consumes 26,000 Btus per hour. Assuming the unit operates at peak operation for one hour based on the DOE's 2006 unit cost of natural gas, it would only cost 36 cents an hour to run the appliance. Operating the appliance for two hours per day for a month and adding the minimal cost of the pilot, the monthly cost would be approximately $26.64 per month.¹
Note: Most vent-free units have thermostats that lower the heat when they reach a pre-set temperature, so these appliances DO NOT operate at peak output all of the time. Consequently, the operating cost of a vent-free appliance equipped with a thermostat is even less than the one given in the example above.

Can you reduce your heating bill by zone heating?

Yes. Strategically placing a vent-free gas heater, fireplace, stove or log set in rooms you use most can significantly cut your heating bill. Vent-free appliances put the heat where you want it and when you need it, allowing you to turn down the thermostat on your central furnace. According to the American Gas Association, turning the thermostat back 10 to 15 percent for eight hours per day can cut your heating bill by 10 percent.²

How much do people save using a vent-free product to zone-heat their home?

Savings vary depending on your home and how you use your heating appliances. A conservative calculation using DOE average use and cost data for home heating with natural gas shows using the central furnace to supply two-thirds of a home's heat and a vent-free appliance to provide zone heating in primary living areas results in a 12 percent cut in fuel costs.3 Supplemental vent-free gas heating appliances provide the heat where it is desired and not throughout the whole house. The greater the use of the vent-free appliance, the greater the savings.

3 - Safety

Are vent-free products safe?

Yes. Vent-free gas products are safe provided they are installed and operated in accordance with manufacturer's instructions, which is important for all home appliances. All vent-free gas appliances are permanently installed and have defined distances to combustible surfaces. They also have safety grills for heaters, fire screens and hoods for gas logs and fireplaces.

What technology is used to help assure the safety of vent-free products?

Every vent-free heating unit sold in the United States must have a tamper-resistant, precision-engineered oxygen detection safety sensor (ODS), which is equivalent in function and reliability to an electrical circuit breaker. The ODS automatically shuts off the applian
