Essentially, these products must meet the general requirements for all combustible heating appliances established in the 2002 version of the National Fire Protection Association’s standards that require ventless fireplaces to have factory-installed carbon monoxide monitors and oxygen detection safety devices (ODS). Traditionally, a fireplace required a chimney and wooden logs and lots of time and energy, but ventless gas fireplaces essentially use natural gases, such as propane, along with the air in your home to produce heat. In a B-vented unit, the most commonly used in homes and apartments with existing fireplaces, the air used for combustion comes from inside the house while exhaust gases are vented outside through a pipe run up an existing chimney or installed as a stand-alone vent stack. Ventless fireplaces that are connected to a gas or propane line require professional installation by a gas or plumbing contractor, and shouldn’t have a heating capacity that exceeds the appropriate room size recommended by the manufacturer. Up-to-date pricing and reviews for Ventless Gas Fireplaces on the market can be found at the fireplace models website.
Ventless fireplaces have special burners underneath the logs that allow enough air to combust natural gas efficiently and produce a minimal amount of carbon monoxide. The industry says that today’s vent-free fireplaces operate well within national standards and recommendations concerning these five byproducts of gas combustion: carbon monoxide, carbon dioxide, nitrogen dioxide, oxygen, and water vapor (humidity). Many of the gas fireplaces sold today evacuate combustion products using a vertical chimney (gas vent), which takes advantage of the natural draft caused by the temperature of the flame (hot air rises).
If you adore the look and feel of a real, wood-burning fire, you’ll love vented gas logs These sets can be installed in an existing fireplace, making them perfect for homeowners who are looking for something more efficient than a wood-burning fireplace. Ventless fireplaces are standalone structures that function off natural gas, propane, alcohol-based gels, or electricity, but do not require a vent or open chimney flue to heat a room like traditional gas or wood-burning fireplaces,” says Kaley Galinsky, fireplace and outdoor fire merchant at The Home Depot They are a good alternative for creating the same warm atmosphere.” Vent-free products are typically the most efficient of all fireplaces or gas logs since all the heat is generated into the room or home.
Ventless gas fireplaces are heating devices that use natural gas or propane to heat air in a living space. Gas logs are designed to be installed only in wood burning fireplaces, or in some cases, a ventless firebox that is factory approved for aftermarket ventless logs. So if you like the looks of the vented gas logs you see on our website, they would require you to have installed a wood burning fireplace with a gas line piped into it. Vented gas logs are much more for enjoyment and realism than for heat.
Vented Gas Logs Require a Fully Functional Wood Burning Fireplace and must be burned with the damper open, Ventless (or Vent Free) Gas Logs can be installed in either a wood burning fireplace, or a ventless fireplace that is rated for aftermarket ventless logs and are burned with the damper closed. Alternatively called unvented, vent-free, or ventless, this type of indoor fireplace pipes natural gas or propane into a gas unit, with flames running through gaps in artificial ceramic fiber logs. When an unsealed (non-direct-vent) gas fireplace has been installed in a home that has a lower pressure than outside, the house can become a more efficient chimney than the fireplace chimney itself – especially if the chimney is located on an outside wall.
As of September 2003, an agreement between the Government of Canada and the Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI) established an energy efficiency rating system for vented gas fireplaces. A vent-free (also called a ventless application) gas-burning fireplace typically has a lower cost because there’s no vent pipe involved, says Hemmelgarn of My Hoosier Hearth The average cost for clients of My Hoosier Hearth for a vent-free box, logs, cabinet and installation can cost $2,000-$4,000. This vent can be a traditional chimney, but gas-burning fireplaces don’t require a vertically vented channel, so as long as there is access to natural gas lines and a vent to the exterior (such as built into the wall), a vented gas-burning fireplace can be installed in almost any location in a home.
It all depends on your needs, but vented sets have a more realistic flame and can be used in an existing real wood fireplace, while ventless logs are more efficient. Ventless logs don’t use a chimney or flue so the gases that are produced have nowhere to go. However, ventless fireplaces come with oxygen depletion sensors that will shut off the unit if oxygen reaches an unsafe level. If you’re looking to add a supplemental, efficient heat source to your home, you may want to go with a vent-free gas log set Unlike vented, these logs do not require a chimney or flue to operate, allowing more heat to stay in your home.
This, along with their high fuel consumption, makes vented logs less efficient than their vent-free counterparts, but more efficient than traditional wood-burning fireplaces. Vented gas logs produce carbon monoxide emissions so your fireplace must have a chimney or flue. More than 17 million households use ventless gas fireplaces, log sets, and stoves as a supplemental heating appliance.
Because they don’t require connection to a chimney or flue, ventless fireplaces can be inexpensively installed in almost any room of the house. Ventless fireplaces fueled by gas or propane rely on indoor air for combustion, and they exhaust a low level of their combustion gases into the room in which they’re located. Ventless fireplaces are typically freestanding units that don’t require a flue or chimney to exhaust combustion air to the outdoors, making them relatively easy to install in any room.
The flame is mostly blue, therefore ventless gas logs lack the visual appeal and beauty of a wood or vented gas fireplace. But because non-vented gas logs and fireplaces vent exhaust into the home, this advantage is offset with added carbon monoxide concerns. Ventless fireplaces are more energy efficient than vented fireplaces because no heat escapes up the flue, so you’ll save money on gas utility bills.
A note about fuel: Ventless fireplaces are powered by either natural gas (NG) or propane (LG), and while you can shop for models that display either the NG or LG designation, virtually any gas fireplace can be converted from one type of fuel to the other through the installation of a converter. All vent free gas fireplaces operate without a chimney, flue or vent and can be installed in any room of your house. Some ventless fireplace proponents say that newer units use catalytic-converter technology that cleans hot air as it leaves the combustion chamber, and that if ventless fireplaces are properly installed and serviced, they should work well and safely.
If these dealers were being absolutely truthful with their customers, the question should come out: For $500, you can have this unvented gas log that will throw off heat, water vapour (adding to the humidity levels in the home), traces of carbon monoxide, sulphur dioxide and nitrous oxides, and may, if not maintained, operated or installed correctly, kill you and your family in your sleep. It is therefore important to install a ventless gas fireplace in a room that is large enough to provide the required amounts of air and oxygen for combustion. If you have additional questions about these products, reach out to Cape Cod’s heating product experts at Breakaway We carry top heating brands, like Savannah (gas fireplaces), Vantage Hearth (gas inserts), and Tri-Flame (gas logs).
Vented gas logs vent up your existing chimney, while vent-free gas logs vent all of the heat, and exhaust, into the house (they do not require a chimney or flue). With a vent-free or ventless fireplace, he said, air from inside the house is taken into the firebox, where it is used to support combustion, and the byproducts are exhausted back into the house. The room with the vent-free propane gas firelogs must have adequate oxygen and a source of fresh air to replenish the oxygen lost in combustion.
Vent-free gas fireplaces burn extremely efficiently, and because they don’t have vents, all heat is returned to the room, meaning you’ll realize the full heating potential of your fireplace. According to the VGPA, ventless fireplaces can be safely operated in tight homes because “an unvented gas heating appliance would be operating less during the usage period.” This means that the amount of nitrogen dioxide in the room would be lower. Ventless gas fireplaces differ from vented gas fireplaces in terms of the logs, flame patterning, and most notably, the method of venting.
Even that alternative to the wood-burning fireplace, the vented gas fireplace, is being installed in fewer numbers due to the rise of air-tight homes , which save energy by closing off all possible thermal passages. 6. In a very tight house, unless a window is opened during use, an unvented fireplace can cause indoor air pollution” consisting of traces of carbon monoxide, and various other chemicals plus large quantities of water vapor. Under these conditions, the house can become a better chimney than the chimney itself (see sidebar on page 20), disrupting the flame and drawing carbon monoxide and other combustion products back into the living area.
If your home-building or renovation plans include an efficient gas fireplace, take some time to plan the installation so that the fireplace can effectively contribute to your heating needs. Some fireplaces can be connected to a certain amount of ductwork (much like a furnace), which can help distribute heat to more remote areas of the home while preventing overheating of the room in which the fireplace is installed. To be installed in an energy-efficient R-2000 home, a gas fireplace must be either direct-vented (sealed) or power-vented.
Compared with wood fireplaces, natural gas and propane fireplaces produce much less carbon monoxide and particulate emissions. Like other ethanol fireplaces, Accalia doesn’t need any venting and can be installed in houses and apartments without a chimney. The increased amount of heat means vent-free gas logs are much more efficient than vented sets.
Just like a traditional wood-burning fire, vented gas logs produce carbon monoxide emissions. Like ventless gas fireplaces, vented gas fireplaces provide a decent amount of heat to the room in which they’re located, but often need a boost from the heat of a furnace to make a room comfortable for an extended period of time. Ventless electric fireplaces, unlike their gas-powered counterparts, will not emit any combustion gases back into the room in which they’re located, but they also emit a low level of heat.
Fireplaces that do not require venting will be fueled by gas or propane, and rely on indoor air for combustion. The second inefficient method is called either B Vent” or Natural Vent.” A firebox is designed around a set of logs which cannot be switched, less gas is burned, and with only a few exceptions, the doors must remain open which also pulls already heated air up the chimney. Wood burning, vented fireplaces can also pollute the air with ash and debris, so ventless models are viewed as a better choice for the environment and user’s health.”
In order for a traditional gas or wood fireplace to operate, two vents need to be installed: One that brings fresh air in, and another that pushes fumes and debris out. The ProCom line is marketed through a broad range of dependable retailers and features a variety of products that range from ventless gas wall heaters to an affordable selection of ventless gas fireplaces and log sets. The ventless gas fireplaces allow for installation in any room without the need for venting-making them a terrific choice for your home.
Ventless products are fueled by natural gas or propane and their engineered burners provide environmentally clean, efficient, burning heat. Ventless gas fireplaces and stoves are energy efficient, safe and offer homeowners a way to add additional heat to their homes. Ventless gas fireplaces and gas stoves are available in natural gas or propane, and are intended to be used as a secondary heat source for a home.
Power vented gas fireplaces can be installed where other types of fireplaces might not work, such as a freestanding wall. Vent-free hearth products can be installed without venting up a chimney or to the exterior of the house. Natural vent (also referred to as B-vent) hearth products take in combustion air from inside the home and vent products of combustion outside home via a brick and mortar chimney or pipe venting system installed through the roof.
Ventless fireplaces have very high efficiency ratings because they recirculate all the heat into the room they are installed in. Also, keep in mind that the product directions usually indicate that a window should be left slightly open when using the fireplace. But one family who had a close call with carbon monoxide poisoning is raising questions about ventless fireplaces that don’t require a chimney or vent to the outdoors. A vent also doesn’t have to be reliant on the presence of a chimney, as vented LPG gas heaters can vent horizontally through an exterior wall, which gives you greater installation flexibility.
One of the biggest complaints we hear about vent free gas fireplaces is that the flames look small and do not give a very authentic or beautiful look and feel when compared to a vented model or a traditional wood burning fireplace. A large, open space, such as a great room, should handle a ventless gas/propane fireplace with a 25,000 BTU or higher output, akin to the heat output from a sealed and vented gas fireplace. These types of gas fireplaces and heaters have an added level of chimney safety, as they are built to exhaust the byproducts of combustion to the outdoors.
Since ventless gas logs exhaust into the home, there is an added risk over vented gas fireplaces. Since ventless gas products require no vent or chimney, they cost less to install, compared to vented gas appliances. While the Centers for Disease Control (CDC) does not specifically track deaths or injuries from exposure to the carbon monoxide gas produced by ventless fireplaces, about 15,000 Americans suffer from exposure to CO annually (all means) and nearly 500 die. Be sure to visit fireplace models for the best Ventless Gas Fireplaces on the market to buy.
Many of today’s models include built-in carbon monoxide (CO) detectors and oxygen detection sensors (ODS), which are designed to monitor air quality in the room Because a ventless fireplace does not have a fresh air intake vent, the fire burns the oxygen in the room. Because vent free fireplaces burn in completely clean combustion and no venting is necessary, all warm air stays inside your home resulting in better heating. In addition, because of the heat they generate, ventless gas logs have tall mantel clearance requirements that often disqualify them as options for installation.
