FAQs - Flueless Gas Fires

How do I learn more about flueless gas fires?

Superior Fires has teamed up with Smeg to provide a handy video guide to buying a new flueless gas fire. Please select the link Superior Fires - Smeg 50's Style Retro Flueless Gas Fire to start watching. Subtitles are available (displayed at the bottom of the video) by pressing the icon in the bottom right hand side of the YouTube window.

Can I have a flueless efficient gas fire or stove?

Our exciting range of flueless gas fires and stoves are the perfect flat wall, no chimney solution to instant warmth. Our innovative technology provides a flexible design for your house or apartment, allowing you to install a fire not only in the living room, but also dining room, office, study, and kitchen.* 

If you have a natural gas supply** and can run a standard 8mm gas pipe to the fire installation point, while ensuring you have the minimum room size and adequate ventilation you can benefit from this technology.

*Flueless fires are not permitted in the bathroom.
**Available in natural gas (NG). Selected models are also available in LPG.

How does this work?

Flueless fires incorporate the latest in gas fire technology and do not need a chimney or flue to operate. Instead, the combustion gases pass through a catalytic converter system, positioned at the top of the appliance, which converts carbon monoxide into harmless carbon dioxide and water vapour, levels of which are so low they are typically present in fresh air. In fact, the catalytic converter works so effectively that it can actually help to clean the air by neutralising airborne particles and odours, therefore helping to reduce household allergies.

How long does the catalytic converter last?

Independent tests commissioned to establish the life expectancy of the catalytic converter have proved that even after 16,957 hours (approximately equivalent to 27 years and eight months of normal use)* the catalytic converter is as effective as when it is new.
*Calculation is based on the assumption of 4 hours a day for 5 months of the year.

Are they safe?

For complete safety and peace of mind all of our fires incorporate an Oxygen Depletion Sensor (ODS), which detect when the oxygen levels in the room fall below a specified level and cause the pilot flame to lift away from the sensing probe. This activates the Flame Failure Device (FFD), which cuts off the gas supply to the fire and renders the appliance safe. For additional safety, all of our flueless fires are fitted with a catalytic converter system to ensure excellent levels of air quality.

What ventilation is required?

Most heating appliances need ventilation to maintain the correct level of oxygen in the room. All of our flueless appliances installed in the UK require only 100cm² of additional purpose provided ventilation.*

*For installation in the Republic of Ireland, two fixed openings are required with a minimum effective opening each of 60cm². Both ventilators should be fitted on the same wall, one at high level and one low level with a minimum vertical separation of 160cm².

What about condensation?

All of our flueless fires are designed to supplement central heating and should be used as a secondary heat source only. Therefore, the background ambient temperature of the room will prevent any moisture from condensing on colder surfaces such as single glazed windows.

What about installation and servicing?

All gas fires must be installed by a Gas Safe registered engineer. Flueless fires are very popular with fitter's as they are relatively simple to install and can be fitted in literally a fraction of the cost and tim­­e it takes to fit a conventional gas fire. We also provide a fitting template with every flueless fire that is used to help with installation and because flueless fires do not require the use of a chimney or flue for operation the servicing costs are considerably cheaper than conventional gas fires.

Eco-friendly – reducing the Greenhouse Effect

We all have our part to play in making our homes more environmentally friendly and flueless technology has been awarded five stars for eco value for money, by leading eco-consultant Donnachadh McCarthy. Article from the Sunday Times, 2006. If the 15 million flued gas fires in the UK were replaced by flueless fires, we would save 40,260,000,000 kW of gas every year which would in turn reduce carbon dioxide emissions by over 7,649,400 tonnes every year.*
*Calculation is based on the assumption of 4 hours a day for 5 months of the year.

A flueless gas fire converts 100% of the gas to heat unlike open coal effect fires which convert as little as 10%. Typically running costs are less than 9 pence per hour on high, which is approximately a third of the running cost of a conventional gas fire. By choosing a flueless gas fire it is possible to make a real contribution towards reducing global warming and lower gas bills at the same time.
