Flueless Gas Fires
As the name suggests, flueless inset gas fires don't require a flue and have a heat efficiency of 100%. They use a catalytic converter to clean the fumes; these catalytic converters are rated to last for 27 years.
Flueless gas fires don't require either a chimney or a flue. This is because they use a catalytic converter, which converts carbon monoxide to carbon dioxide and water. The flueless fires can cause vapour in the room and also need a permanent air vent to outside.
Even if your home does not have a chimney or flue, there are balanced flue gas fires and flueless gas fires available which allow you to enjoy a real flame.
Technically, a flue is any open vertical space in a chimney that allows smoke to escape the home from the firebox. But because every chimney's flue must be lined, a chimney liner is usually referred to as the flue, as well. Every wood-burning or gas fireplace has a flue.
Yes, traditional gas fireplaces typically require a chimney or a vent to safely expel the byproducts of combustion (like carbon monoxide) outside the home. However, there are ventless or vent-free gas fireplace options available that do not need a chimney or external venting.
Ventless Gas Fireplace
As the name indicates these fireplaces do not need a vent; there is no significant exhaust from the fire itself to make a vent or flue necessary. These types of fireplaces are the ones you see built into walls of more modern homes.
So, do I need a chimney to have a fireplace? The short answer is no! As fireplace technology has advanced, there are many makes and models that don't require a chimney to work – this way, you don't miss out on the warmth, ambience and style that a fireplace brings to a home, regardless of your property type.
The simple answer is yes, and that's for safety reasons. A flue is necessary to effectively and safely remove harmful gases – such as carbon monoxide – which are created when the gas fuel is burnt. They are safely transported into the air outside the home.
Often in older houses, which have plenty of drafts through floors and windows, no additional ventilation may be necessary. But all modern homes do require ventilation when a gas fire that are over 6.9 kw and solid fuel stoves that are over 5kw are in use. Whereas all open solid fuel fires require an air vent by law.
Electric fires work by using a fan heater that distributes hot air outwards into the room. The main difference between electric fireplaces and gas-powered ones is that electric fires don't need to be vented by means of a flue to the outside like gas models do. This means they can be positioned anywhere in your home.
Yes. The flue on pellet fires is small and can readily be installed internally or externally.
By a long shot, not everyone reports that they have had a chimney fire, yet there are more than 25,000 chimney fires reported in the U.S. annually. It's good to know the common causes of chimney fires and how to avoid them.
For conventional flue gas fires to function safely and correctly, they must be connected to a chimney/ flue, some may require additional ventilation.
Fluorine would be an excellent choice. Chlorine trifluoride is one of the most vigorous oxidizers with no oxygen. Also, hydrogen and acetylene are two combustible substances that ignite immediately when in contact with chlorine, without any need for oxygen, chlorine having the role of the oxygen as the oxidizer.
Although it is not necessarily a legal requirement to fit a flue liner for a woodburning stove, most stove installers would recommend you install one as in most cases it can be hard to determine the quality and potential performance of the chimney just by looking at it.
Open wood burning and coal fires require a class 1 flue liner with a minimum diameter of 200mm. Open fires with larger fireplace openings (usually freestanding grates) will need larger flue sizes calculated alongside the height of the chimney and required ventilation.
Because electric fireplaces do not burn fuel internally or produce any emissions, venting is not required. This is great news because the lack of venting means that electric fireplaces can run more efficiently - none of the heat produced is escaping out via flues and chimneys.
Exhaust fans are more affordable and require less maintenance compared to kitchen chimneys. While exhaust fans are effective for ventilation, they might not be as efficient in dealing with grease and odours.
Balanced Flue Fires
If you are in the market for a gas fire but do not have a chimney or flue look no further than this balanced flue gas fire range. At Stoves Are Us, we offer a diverse range of balanced flue fires to meet every taste and requirement.
They can be installed anywhere because they don't require a vent. They produce the most realistic imitation flames. Because the flames are cool to the touch, they are safe for pets, children, and commercial spaces. Water vapor fireplaces don't produce harmful emissions.
Modern fireplaces are generally considered more efficient, customisable and compact compared to traditional options. They can be very compact and built into most rooms you'd want a fireplace in. Because of this they are an option growing in popularity.
Electric fireplaces, water vapor fireplaces, ventless gas fireplaces, balanced flue fireplaces, and B-vent fireplaces don't require a chimney. Some fireplaces without chimneys still need a ventilation source. Balanced flue fireplaces and B-vent fireplaces require pipes for ventilation instead of a chimney.
Open the damper fully
A lack of airflow can rob fire of the ability to combust wood properly, causing more smoke to be produced. This can be avoided by fully opening the damper before starting the fire. The damper is a small door on top of the fireplace that opens up to the outside through the chimney.
The combustion process in ventless gas fireplaces releases various byproducts, including carbon monoxide (CO) and nitrogen dioxide (NO2), directly into the indoor environment. These byproducts can have detrimental effects on indoor air quality and, consequently, on the health and well-being of occupants.
