By choosing one of our gas fires, you can be sure you’re buying a rigorously tested and safe ventless gas fire, beautifully designed by our team. We pride ourselves on every CVO flueless gas fire being an efficient heat source and providing a stunning focal point for any home.
How Do Flueless Gas Fires Work?
There are clear benefits to choosing a flueless gas fireplace for your home; the stylish and sleek aesthetics combined with the functionality they bring makes for a winning combination if you’re looking for a decorative installation for your home that can provide you with some extra heat. But how do flueless gas fires actually work?
The clue’s in the name: all of our flueless gas fires don’t require flues, pipes or chimneys, improving the ease of installation in many homes. All emissions come from the flueless fire vent on the top or front of the fire. The flueless fire will draw in clean air from the room through the fire vent, and after combustion, use that to fuel the flame in your fire. We ensure all of our flueless gas fires are completely clean burning, making them ideal for most properties – not requiring catalytic converters or any other filters. This can make flueless fireplaces an attractive choice for contemporary and traditional properties, delivering on both practical and aesthetic benefits.
Pros & Cons Of Flueless Gas Fires
Advantages of flueless gas fires:
Flueless Gas Fires have an outstanding safety record because they’re designed to burn incredibly cleanly. Most manufacturers use filters or catalytic converters to clean out the emissions, but our unique clean burner technology has taken the next step forward, no longer requiring a filter or other device – also giving our flueless fires a flame you won’t find elsewhere. That means no flue pipes, chimneys or anything else to install in your house to have a beautiful flueless gas fireplace!
Our flueless gas fires are all designed and manufactured with reliability, as well as style, in mind. With normal usage, flueless gas fires can last for decades in both residential and commercial properties meaning great value for money and no expensive repairs!
Saving Money: Gas is the cheapest form of energy to use – over 70% cheaper “per kw/h” of heat than wood, electric or bio-ethanol. This makes our flueless gas fireplaces one of the most energy (and money!) efficient choices.
Flueless Fires are Easy to Install: Our flueless gas fireplaces can be installed quickly and easily if the gas supply is nearby.
Flueless Fireplaces are Easy to Use: Using the control knob on our flueless gas fires you can easily adjust the flame size and heat output to suit you. This makes our flueless gas fires suitable for all year round use, giving you more heat in the winter and less in the summer.
Extra Heat when you want it: Flueless stoves are ideal as a secondary heat source for your home; one of our flueless gas fires will give you between 2.0kw and 3.5kw of heat and will cost you only 9p to 15p per hour to run. For the same amount of heat output, an electric fire can cost anywhere between 30p and 53p.
Disadvantages of flueless gas fires:
- Flueless gas fires are unable to be your primary source of heat. To be able to install one of our flueless fireplaces in your property, you must have a primary heat source. The gas pressure must be maintained at the manufacturer’s stated level or the combustion will change.
- There are minimum room size requirements. Every flueless fire has a minimum room size specified in the technical specifications, and it’s vital you meet or exceed this size to install your flueless gas fire safely. The minimum room size is calculated as the height x depth x width in meters – giving a m3 result.
You will need to install an air vent into the same room as the flueless gas fire. Having a supply of fresh air from outside is essential with some of our flueless gas fire appliances. This is to make sure the fire can draw in enough fresh air to safely function, and to prevent damage to the fire.
- Flueless gas fireplaces may not produce enough heat for your specific needs. Although this shouldn’t be an issue, as our flueless gas fires are only intended as a secondary heat source, some people may feel as though their flueless gas fire doesn’t emit enough heat.

Flueless Gas Fire Frequently Asked Questions
Why don’t your flueless gas fires have glass fronts?
We are the only manufacturer who can offer a living flame flueless fire without the need for a glass screen – its purpose is to drive emissions through a catalytic converter, but our open flame gas fires are so clean burning that we need neither. This helps to create an even better aesthetic, with real open flames making for an impressive focal point to any space.
What is an ODS safety device?
All flueless gas fires sold in the EU have an ODS pilot system. This is a safety device which will shut off the gas to the main burner if there is a problem. The CE standard says this must operate if the CO in the room reaches a maximum of 80ppm; our fires shut off at around 25ppm. If the flueless gas fire is installed in a room smaller than the minimum and with the wrong air vent or a blocked vent, it will shut down approximately 1 hour after being started. This can sometimes lead people to think the fire is faulty, but it’s actually indicating an installation fault which needs to be rectified for safe usage. Another indication of an installation fault is that the fire can stop suddenly and restart later with no apparent fault. In any of these instances, it’s important not to use the fire and get a gas engineer to check the complete installation against the manufacturers instructions.
Are flueless gas fires reliable?
Flueless gas fires are a very reliable option for any property! A CVO Flueless Fireline was installed in a Central London Restaurant in December 2003 and worked continuously until the restaurant was closed in May 2007. This fire operated for typically 15hrs/day, 6 days a week for 41 months, equaling about 14,760 hours. This is equivalent to nearly 25 years operating in a domestic property.
How flexible of an option are flueless gas fires?
If you have rooms you don’t often use which are difficult or expensive to heat with other traditional heat sources, such as basements, room extensions and conservatories, a flueless gas fire could be the perfect choice. If your space has a primary source of heat, inset flueless gas fires can be installed almost anywhere, even on an inside wall.
Do Flueless Gas Fires Cause Condensation?
A common misconception is that flueless gas fires might cause condensation in your home; this is untrue, and as flueless gas fires are a secondary heat source working in tandem with central heating, the background air temperature prevents most of the moisture from condensing and it is dispersed by normal air movement.
What does PPM mean?
It means “parts per million” in the context of carbon emission tests. During the CE tests, this is measured at the outlet of the flueless fire appliance in a very concentrated sample direct from the burner. Once this has been diluted by the oxygen in the room the CO concentration is tiny and very safe.
What makes our flueless gas fires different?
All of our flueless gas fires are handmade in the UK using locally sourced materials. Every flueless fireplace is individually handmade and tested for up to 1 hour before being packed and shipped. Our flueless gas fireplaces don’t need catalytic converters so also don’t not need glass on the front, leaving a beautiful open living flame.
How safe are flueless gas fires?
Flueless gas fires are very safe. About 20 million are installed in the USA and they can be found in Australia and Japan – two countries with strict environmental laws. The emissions from flueless fires are very small; the fire needs an air vent in the room, providing fresh oxygen to replace the oxygen burnt by the fire and keep the air fresh. You should also consider that as a manufacturer our factory is inspected each year by officials from CE to ensure we are making products to the exact standards set out by EU law. Additionally, every month we do our own internal audit on our appliances and we also test the components when they arrive at the factory and before we build our flueless gas fires. This is what makes our flueless fireplaces the most safe and reliable on the market. Our flueless fires are also fitted with safety devices that will shut the fire off if someone tampers with the fire or the air quality is reduced. Each of our flueless gas fires shuts down at only 25ppm and it is reported that exposure to CO of levels of 800ppm and higher are considered hazardous.
Is burning wood safer than flueless gas fires?
The emissions from a wood burning appliance are much higher than a flueless gas fire (they can be up to 50x greater). If they are installed with a faulty flue system or the door seal is damaged these emissions will come into the room. Wood burners do not have an ODS system, hence why it is law to have a CO monitor with a wood burner.
Why do I need to install an air vent in the room?
The flueless fire burns oxygen from the room to ensure that the flame is clean. As the fire uses a small quantity of the air from within the room, this must be replaced by fresh air supplied by the wall vent from outside. If the air vent is the wrong size and does not supply enough air or becomes blocked all together, after a period of time the volume of used air will reach a level where the pilot will operate to shut the fire off. This is normally shown by an increase in noise from the pilot. This is why every flueless gas fire has a minimum room size and a minimum specified volume of “free air” that must be supplied into the room. We supply high quality vents for around £40 that provide a trickle of fresh air and ensure you don’t get drafts into your room. You must never block the vent up otherwise the safety device will operate and shut the fire down.
Do flueless gas fires cause stains on the wall?
Without the catalytic convertors and glass screen it means the emissions from our flueless gas fireplaces are diluted quicker by the fresh air. With other brands of flueless fires the vent on the top of the appliance can concentrate the heat into one fixed outlet area and cause stains on the wall directly above the fire. We’ve designed our range of flueless fires to avoid this problem and avoid any unsightly stains!
How do the running costs of flueless gas fires compare with other types of fires?
When replacing a conventional or balanced flue gas fire with a flueless gas fire you will lower your overall gas bills by up to 70%. The annual cost of using a flueless gas fire is around £50/year, compared to an electric fire of £150/year or burning wood at £500/year for the same heat – although with the cost of living increasing, these numbers might be outdated! When considering other appliances, with safety in mind, you should also consider that the emissions from a wood burning fire are very high and these appliances do not have a safety device to shut them down. The dust particles have also been proven to be very hazardous, so although wood burning fires might seem glamorous, great consideration should be put into researching the health hazards of burning wood first.
Does a flueless gas fire cause smells in the room?
If it is installed correctly, with an air vent in the room, and operated as instructed then no. As described above the flueless gas fire uses fresh air from the room, so if the air quality is poor then this poor quality air will be drawn into the fire and burned causing a smell. Whenever the cause of smells has been investigated it has not been the flueless gas stove but by people doing something to the air quality or changes in the home. A few examples might be burning scented candles, using air fresheners, decorating, new furniture, spraying aerosols, installing new carpets and many other things.
How economical and fuel efficient are flueless gas fires?
The energy efficiency of a flueless gas fire is 100%. This is partly because there is no flue or chimney through which heat can escape and this means that all the heat remains in the room. As a result of this, running costs of flueless gas stoves are very low and can lead to a considerable saving for the householder. A conventional chimney or flue set up draws a large amount of air from a house. This means the heat generated by Central Heating systems, when the fire is not in use, is also being lost up the chimney. With a flueless gas stove this situation does not occur.
Can I install a shelf above a flueless fire?
Flueless gas fires are designed to be wall mounted, but it’s important to remember that anything above the fire must be done in line with the CE approval. The flueless fires that we sell are approved with a special deflector which allows a shelf above however this must be done in line with the installation booklet. This deflector must be ordered at the time of ordering the flueless fire, but please get in touch if you’d like more details!
Can I install a flueless fire into a wall?
Wall hung flueless gas fires are designed to be wall mounted however the CVO flueless gas fire is also approved as a recessed version which has allowed customers to install the fire into the wall. Feel free to get in touch if you’re looking for more details!
