Do you need a chimney with a gas fire?

With a flueless gas fire, you don't need to have a chimney at all to enjoy a fireplace. You don't need to carry out as much building work to install one, either. You will just need to fit a 100cm2 ventilation brick on any exterior wall and connect your fire to a gas pipe.

Ventilation needs to be provided to the chimney space to avoid moisture collecting on the soot and smoke deposits within the chimney and forming damp areas, this can easily be achieved by building in an air-brick as the fireplace opening is bricked up.

How much air does a fire need?

Oxygen. Air contains about 21 percent oxygen, and most fires require at least 16 percent oxygen content to burn. Oxygen supports the chemical processes that occur during fire. When fuel burns, it reacts with oxygen from the surrounding air, releasing heat and generating combustion products (gases, smoke, embers, etc.).

Higher efficiency gas fireplaces keep chimneys cooler, but they can also cause condensation in the chimney, which corrodes the surface.

Are open gas fires safe?

There are two main reasons why glass-fronted gas fires are safer than open-fronted gas fires. Firstly, with a gas fire that has a protective glass front, there is no danger of the flames coming into contact with flammable objects in the room, so the fire risk is almost completely eliminated.

Do flueless gas fires cause condensation?

Flueless gas heaters just chuck it all into the air inside the house. The water vapour produced will raise the relative humidity and increase the likelihood of condensation; the carbon dioxide will make you feel sleepy, and the carbon monoxide – if present – could damage your health.

Flueless gas fires have a lower heat rating than other fires of 2.5kw (other gas fires can go up to 6kw), but as they're 100% efficient, all of the heat goes into the room. 30 cubic metres should be adequate for most flueless fires, but please check the model requirements and your room size before buying.

How far does a flue need to be above a roof?

The chimney should extend at least 3 feet above the roof surface it penetrates and 2 feet higher than any roofline or other obstacle within a horizontal distance of 10 feet. Taller chimneys make more draft, but chimneys exposed to outside cold don't. See our section on chimneys.
