If you’re swaying towards in-built wood fireplaces, Sydney you’re leaning in the right direction. In-builts are gaining popularity in the heating space, both for homes and offices. They have myriad advantages and very few down-sides, the main one being expense. They require professional installation, ideally while the house is being built. Because the units fit right inside the wall, unsafe excavation or flue-ing could bring the house down, literally.

This – however – is the first benefit of in-built heating units. Because they fit right inside the wall, they don’t use up any of your floor space. This way, they can be installed even in small rooms without reducing available living space. It doesn’t interfere with the rest of your furniture or the layout of your space. In fact, if you insert it in a wall divider, you can heat two rooms at once, sometimes creating different visuals on either side.

Inbuilt Fireplaces


In-built fireplaces are designed to fit flush against the wall. That means there should be no difference in the wall’s flatness. The in-built has to essentially become part of the wall. Because of this, they are designed to be attractive. The eye will automatically be drawn to that break in the wall, so the sight must be gorgeous. Style options range from rustic to contemporary, framed to edgeless, matte to glossy. There are so many choices that you’re sure to find an in-built to suit your style.

In-builts can be wood-burning, gas-burning, or charcoal burning. Ethanol fireplaces can’t be in-built though, because the flame is often naked, or only partially covered. Using a naked flame in an in-built can easily become a fire hazard. Also, in-builts are linked to flue systems, which are redundant given the low heat signature of biofuel furnaces.


Because they have to be built into walls that often contain flammable materials, in-builts are designed with full insulation. They always have a glass viewing panel, both for aesthetic and safety reasons. It lets you watch the fire, but it also prevents and sparks or embers from floating into the rest of the room, potentially starting an accidental fire. The viewing pane and other front-facing portions of the fireplace are designed to stay cool to the touch.

This feature avoids accidental burns and scorches while handling the furnace. Some units have hinged doors that open upward or upward. The hinge prevents them from slamming shut. The glass viewing panel can also prevent smoke, soot, and ash from spreading into the room. Any emissions are led up the flue, though in-builts have heat boxes that raise the burning temperature, creating efficient fires and eliminating unburnt carbon emissions.

 In-Built Fireplaces


Heat boxes have an additional feature. By pushing the temperature behind the glass to a maximum (while keeping the glass cool), it ensures less fuel is used overall, since every log or briquette is torched to the maximum and turned to complete ash. Their structure and burning mechanism makes them kinder on the environment, both by fuel use and emissions. And because they are fitted into a pre-existing wall, fewer construction materials are used.

Generally speaking, in-builts offer a clean look, but they’re also easier to clean. Gas in-builts are the most popular model, and they don’t give off smoke or produce ash. There’s a limited amount of soot, but this needs to cleaned by a gas plumber two or three times a year. Your only hygiene task is to keep the viewing window clean and shiny.


Modern in-builts come with all sorts of design elements designed for distraction. For gas fireplaces especially, you can buy a unit where the light and heat are distinct features. That means you can turn on the heat while keeping the room dark, in case you want to get some sleep or watch a movie undisrupted by wanton illumination. Alternatively, you can put on the firelights without turning on the heat itself.

These in-builts are manufactured to mimic wood fires, so they use sound technology, waterworks, and other devices to make your gas fire or electric fire look and sound real. It will crackle and the flames will dance, using functions like Opti-myst, Optiflame, Opti-V, and Dancing Fyre. You can add the visual beauty with coloured crushed glass or fireplaces that activate holographic imaging.
