Ventless Gas Appliances - A Safe, Convenient and Efficient Way to Heat the Room You Use Most

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.


Vent-free appliances are similar to other space heating and hearth products, with one exception - they don't have a vent. This allows all of the useable heat to enter a room. Today, vent-free gas appliances include heaters, fireplaces, fireplace inserts, stoves and log sets and, every year manufacturers introduce new designs 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.


Unlike some vented hearth products that require glass fronts, vent-free hearth products provide real, open flames not shielded by glass. In fact, log sets are so real that you may not be able to tell the difference between an open, wood-burning fireplace and a vent-free gas model.

Converting your wood-burning fireplace to a vent-free gas log set eliminates the hassle and mess of hauling in wood, disposing of ashes, lighting uncooperative kindling, tending the fire, and guarding against stray embers. Prior to using vent-free gas logs, it is important to have your chimney cleaned. Consequently, once you convert, you will never need to have your chimney cleaned again.


Vent-free gas heaters, fireplaces, stoves and log sets are the most energy-efficient heating devices on the market. This means that virtually all of the gas burned is turned into useable heat.

Despite recent price increases, natural gas is still the most cost-effective heating fuel in America. Vent-free appliances only cost a few pennies per hour to operate, making the addition of a vent-free gas heater an energy-smart decision.


Installation costs of vent-free products are up to 60 percent less than the cost of installing vented heating cutting through exterior walls or creating an expensive chimney or vent system.

Any of the 62 million homes that are supplied with natural or propane gas can inexpensively have a professional install a vent-free heater, fireplace, stove or log set. It can usually be done in less than an hour.

A certified installer familiar with vent-free products and local building codes can help you choose the right-sized product for your home and install it properly.


Many designs are available with remote controls, either hand-held or wall-mounted, 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.

Vent-free gas appliances eliminate the need for chopping and hauling wood or cleaning up from wood burning in a conventional fireplace.


Vent-free appliances, like all gas appliances, should be annually inspected for proper operation by a qualified service agency. This typically consists of a cleaning, checking the burner and inspecting the appliance's other key components and ignition system.

Owners should review the product manual prior to operating the unit.

Vent-free products do not have chimneys, flues or vents that get clogged, need repair or cleaning, or provide a conduit for unwelcome pests.


While these appliances are typically installed to warm primary living areas, vent-free gas fireplaces, stoves, and heaters can be installed in just about any room, from hard-to-heat basements and additions, or in rooms used less frequently. Vent-free products can even be installed outside to provide heat for your outdoor living areas.

Unlike vented products which have limitations on their placement, vent-free products can be put just about anywhere. On an inside wall, under a window, in a corner or in the middle of a room -- any area with access to a gas line. Always check with your local codes as there may be some restrictions.


Vent-free appliances feature an automatic safety shut-off device (Oxygen Detection System or ODS). The ODS turns off the gas in case of a malfunction. Since 1980, with 17 million units installed in the U.S. alone, the Consumer Product Safety Commission has stated that it is not aware of any documented incident in the CPSC In-Depth Investigation (IDI) database of fatal carbon monoxide poisoning associated with an ODS-equipped vent-free gas heating product. These appliances have earned an outstanding safety record.

Vent-free gas heaters, fireplaces, stoves and log sets meet all of the most relevant indoor air quality standards and guidelines. Vent-free heating devices integrate precision burners and multiple safety features that combine to provide clean combustion and a uniquely safe heating product. - © Copyright 2007-Present
