A flueless gas fire is simply a low output gas fire that doesn't require a chimney or flue to remove the products of combustion from the appliance. However you will in most if not all cases need to have a form of ventilation added to the room. Usually a floor vent or wall vent. This will require a gas safe engineer to install it and service it on an annual basis.

A flueless gas fire is a gas fire that doesn't require a flue so it can be installed where there is no chimney or outside wall. They will require sufficient ventilation to be provided and there will also be a minimum room size in which they can be installed. It is extremely important that they are serviced annually by a suitably qualified gas safe registered engineer.

A flueless gas fire does not require a flue or chimney to release the products of combustion (burnt gas) to the outside air. Instead it uses a catalytic converter to remove the harmful elements. Things to consider when choosing a flueless fire are - Size of room, the heat output of flueless fires is quite a bit less than a conventional gas fire so you may require some other form of heating in the room. A permanent uncloseable vent to outside will be required. Which wall you wish the fire to be mounted, this will also affect where the vent will be installed. Guidance for these requirements will be found in the manufacturers notes and should be read before purchasing. The fire will also require an annual service. The best advice is to speak to a Registered GasSafe Installer (RGI)

A flueless gas fire does not require a flue or chimney. It uses a catalytic converter to clean the products of combustion rather than pushing them outside of the property via a flue or chimney. There are a number of things that must be considered before installing one. . . The manufacturer of the fire will specify a minimum room size, the installation of a air vent and it can only be used as a secondary heat source. ie you must already have a radiator or similar in the room.

A flueless gas fire is exactly what it sounds like, a gas fire that does not require a flue. What this means, in reality, is that a gas fire can be installed into a property without either; a traditional chimney, or a pre-cast block flue. Modern homes are built without chimneys or pre-cast flues. Therefore, flueless gas fires are a perfect solution for homes without chimneys. Flueless gas fires require permanent ventilation to be installed and require annual servicing. All gas appliances should be serviced annually, but it is especially important for flueless gas fires due to the various safety features that need to be maintained. It is always advisable to install a CO detector with a flueless gas fire.

A flueless gas fire requires no chimney or flue. It has a catalytic converter to filter the products of combustion which are emitted into the room. For this reason it is recommended to have a carbon monoxide detector installed in the room. Flueless gas fires always require adequate permanent ventilation from outside to burn efficently and safely. They have built in safety devices and require annual servicing.

A flueless gas fire is a modern appliance, these gas appliances require no flue, the products of combustion are filtered through a catalytic converter before venting into the room this basically means that your fire will not have a flue. Ventilation to the room will be required and installation must be carried out by a gas safe registered engineer with a certificate for fires.

Flueless gas fires are a newer design fire becoming more and more popular in homes. These fires are not intended to be used as a primary heat source, but to enhance visual aspects of a room and provide top up heat, such as in a lounge where there is no chimney/floor. A catalytic converter manufactured within the appliance is incorporated to clean the products of combustion (POC) that are discharged into the room. Designed to convert CO (carbon monoxide) into carbon dioxide (CO2). Many of these are installed with an oxygen depletion device or similar shut off, that turn the appliance off if the oxygen levels reduce by around 1%. A disadvantage of these fires is the need for permanent ventilation to outside and a build up of condensation due to POC being vented into the room.

A flueless gas fire does not require a flue/chimney to remove products of combustion (fumes). Instead it uses a catalytic converter built into the appliance to 'clean' the gasses producing carbon dioxide. For this reason, flueless gas fires are considered the most efficient type of room heater, although they are not recommended to be used as a primary heat source in a dwelling. They are designed to supplement existing heat sources like centrally heated radiators. A purpose provided vent is required through to outside air (usually 100cm2). This is in order for the appliance to breath. Gas fires require air for the gasses to burn efficiently. A downside to flueless gas fires is that they are usually quite low output, so more designed for decorative effect. Condensation can build up in a room containing a flueless gas fire. Water vapour is a natural bi-product of gas when combustion occurs and as the appliances do not require a flue or chimney the water vapour stays within the room if not ventilated properly. As with all gas appliances, a suitable carbon monoxide alarm is required within the room and the appliance should be serviced and safety checked at regular intervals.

A flueless gas fire is probably 100% efficient but don't quote me on that it could be 98%! they have very low kw usage IE: 2-3kw and have NO FLUE! So where do the products of combustion go? well on top of the fire in the decorative top under the surface will be a CATALYTIC CONVERTER, if you look at it from the top most are a kind of honeycomb design, the material soaks up the harmful gases and even though the converters are designed to last the lifetime of the fire it is always advised to have them serviced, inspected each year and definitely have a CARBON MONOXIDE DETECTOR high up towards the ceiling of the room the flueless appliance is in. These do throw out good heat and none of it goes up a chimney, very efficient right!

A flueless fire has no chimney, flue or fireplace. Flueless gas fires are not designed to be the sole source of heat in a room, they are supplementary to the central heating system. A flueless fire works in the opposite way to a normal fire by the products of combustion being released into the room itself. This is helped by a catalytic converter reducing the harmful gases which need to be vented via a vent in the room. The vent in the room supplies air into the room which is being heated. A qualified engineer will determine if a room is suitable for your fire and also to fit it for you.

A flueless gas fire is a gas fire which does not have a flue. That is to say – products of combustion are vented directly into the room and not to outside. These fires typically need to be installed in a larger room and have much more stringent ventilation requirements. It is imperative that flueless gas fires are serviced at least annually and perhaps more frequently dependent upon use.

Most flueless gas fires installed in this country have a 'catalytic convertor' type plate fitted in them to remove harmful gases form entering the room atmosphere, as there is no chimney required to remove spent gases. It is important to consider that they will mostly require combustion ventilation of 100cm2 free airspace and it is vitally important this is both provided and never blocked by the end users, I feel due to this reason they are inappropriate in rental properties, its is vital that flueless gas fires are installed exactly in accordance with the manufacturers instructions and regularly tested for correct operation.

A flueless gas fire does not have a flue directly attached. the products of combustion will exit appliance into the room . A very important thing to remember is always check with the manufacture and a gas safe engineer if the appliance would be ok for the room you wish to install in as you may need to upgrade or install air vents to meat requirements of the fire. The appliance should always be installed to manufactures instructions and carried out by a gas safe engineer. If in any doubt call the manufacture and gas safe.

Flue less gas fire , is what it says in the name . No flue required to disperse the products of combustion but will require a larger size room with ventilation . Always have it installed as per instructions set out by the manufacturers and by a Gas Safe engineer , it will require a service check every year .
