Modern glass-fronted gas fires have transformed the home fireplace experience. Gone are the days of drafty, inefficient gas flames; today’s models are high-efficiency centrepieces combining real fire ambience with cutting-edge design and convenience. Our 16″ glass-fronted gas range exemplifies this, offering options from ultra-modern “hole-in-the-wall” installations to timeless hearth-mounted classics.
A fire – perfect for you
Whether you live in a sleek new apartment without a chimney or a traditional home with an existing fireplace, there’s a glass-fronted gas fire in our range to suit your needs. These fires not only look great, but their sealed glass fronts deliver a new level of efficiency and performance by drastically reducing heated air loss up the chimney.
Below, we explore the four standout models in our 16″ range, each excelling in design, performance, energy efficiency, and installation flexibility.
The Paragon Core BF Balanced Flue gas fire, shown below in a classic marble fireplace surround with a stove-front fascia and a realistic log bed, offers authentic warmth and style even in homes without a chimney. Its glass-front ensures the fire looks great even when off, thanks to a detailed log fuel bed and reflective interior panels that add depth to the flame display.
The Core BF is a groundbreaking model; it’s the first no-chimney 16″ fire to feature our advanced Core burner technology. This technology produces remarkably lifelike flames and glowing embers while also pushing energy efficiency to new heights. In fact, the Core BF boasts a net efficiency of up to 89%, one of the highest ever achieved in our gas fires. With a comfortable 3kW heat output, this fire provides ample warmth for living spaces while using fuel frugally.
Flexible Installation
Installation is incredibly flexible: as a balanced flue fire, the Core BF vents directly outside through an exterior wall, making it suitable for homes without a chimney or flue, perfect for modern builds or conversions. It requires only a slim 4-inch (100 mm) hearth depth if floor-mounted, and it can even be built into walls up to 880 mm thick, giving you freedom to create a fireplace anywhere an external wall is available. Homeowners also love the design versatility: the Core BF can be customised with any of our current range of trims, frets, and fascias, from sleek contemporary frames to decorative period styles.
You can choose a remote-control version for effortless operation, or a convenient manual slide control if you prefer. Like all models in the range, the Core BF is also 20% hydrogen-blend ready, a future-proof feature that ensures it is compatible with emerging greener gas supplies. The Paragon Core BF delivers no-compromise efficiency and beauty, letting you enjoy a genuine fire even in a home with no chimney or fireplace infrastructure.
Our Paragon Core HE (Conventional Flue) gas fire, shown below with a modern four-sided chrome fascia in a traditional mantelpiece. This high-efficiency inset fire combines a glamorous, real flame look with a substantial 4kW heat output to create a cosy focal point.
Designed to provide the ultimate in warm and comfortable living, the Core HE (High Efficiency) model offers a perfect balance of stunning appearance and performance. This glass-fronted fire uses the same advanced Core burner as its BF sibling, giving a beautifully realistic flame picture with flickering flames, glowing embers, and even black reflective glass liners that amplify the depth of the firebed. With a robust 4kW heat output and up to 85% efficiency, the Core HE can quickly fill your room with heat while wasting very little up the chimney.
Conventional flue and added convenience
This model is a conventional flue fire, meaning it’s designed to work with a standard Class 1 chimney or 5″ flue, making it an ideal upgrade for an existing fireplace opening. It only needs a minimal 4″ hearth depth for installation, so it fits neatly into shallow cavities or prefabricated chimneys, too. The Core HE is all about flexible style: it can be fitted with any of our trims, frets, or fascias, whether you want a traditional look (e.g. a brass fret and mantel) or a chic hole-in-the-wall vibe with a four-sided trim.
We offer it with either a high-level smooth-slide control (for easy reach) or a full infrared remote control, so you can ignite and adjust your fire without leaving your armchair. The fire’s mixed log fuel bed gives it a modern wood fire look, creating a contemporary centrepiece even when the flames are off. Just like the balanced flue version, the Core HE is a 20% hydrogen blend-ready, ensuring it will continue to perform as gas supply standards evolve. All these features make the Paragon Core HE a hugely popular choice for those seeking a classic inset fireplace feel with modern efficiency and ease of use.
Paragon Focus HE (Conventional Flue) Our Paragon Focus HE glass-fronted gas fire, shown below, is set in a timeless fireplace surround with brass trim and a coal-effect fuel bed. This model is built for maximum heat output (up to 4.4kW) and comes with a full-width glass window and optional traditional aesthetics, like coal or log fuel beds and various trim styles.
If you desire a little more punch in heat and a broad view of the flames, the Focus HE is the answer. This 16″ inset gas fire is engineered for maximum heat and efficiency, featuring a widened full-length glass window that provides a stunning panoramic flame view and superior heat retention. The Focus HE delivers up to 4.4kW of heat output, the highest in this range, making it ideal for larger rooms or those who love a toasty lounge.
Enjoy a range of looks
Despite this powerful performance, this fire still achieves an impressive net efficiency of around 82%, far more efficient than older open fires. A big appeal of the Focus HE is its chameleon-like ability to take on a range of looks: you can choose a classic coal fuel bed for a traditional glow or a realistic log bed for a wood-fire look. There’s also a selection of trims and frets available, from period-inspired designs to minimalist modern frames, so you can style it to perfectly suit your décor. One unique design touch is its pixelated-edge glass, which gives a clean, neat finish by obscuring the joint between the glass and the frame, creating a truly seamless appearance. Installation is straightforward and flexible: like the Core HE, the Focus HE requires only a 100 mm hearth depth when floor-mounted, making it easy to fit into shallow fireplaces.
Natural Gas or LPG?
It’s compatible with both standard Class 1 chimneys and modern 5″ pre-cast flue systems, expanding where it can be installed. We offer remote or manual slide controls, and an option for Natural Gas or LPG fuel, so even if your home is off the mains gas grid, you can enjoy this fire on bottled gas. Like all our models, it’s built to the very latest standards and is hydrogen-blend ready for future fuel mixes. In essence, the Paragon Focus HE is a high-output, high-efficiency fireplace that combines modern technology with customisable style, giving you the best of both worlds in terms of warmth and design.
Paragon Focus RS BF (Balanced Flue) – The Paragon Focus RS Plus BF gas fire, shown below in a sleek Black Nickel four-sided fascia, exemplifies contemporary design and outstanding efficiency. This balanced flue model is installed “hole-in-the-wall” style with no hearth, seamlessly integrating into modern interiors while delivering up to 4kW of heat with an exceptional 95% efficiency rating.
As one of the most efficient gas fires on the market, the Focus RS Plus BF is the crown jewel of our 16″ range. Being a balanced flue fire, it is completely sealed from the room and vents directly outdoors, allowing installation in homes without a chimney and helping achieve its remarkable energy efficiency.
Outstanding efficiency
The Focus RS Plus BF has a heat output up to 4kW, easily warming your space, but it’s the efficiency that really impresses: it reaches up to 95% net efficiency, meaning very nearly all the gas it burns is converted into useful heat. This means it can significantly reduce running costs and environmental impact. In line with European Class 1 energy standards for appliances, the Focus RS Plus BF is truly a green performer. Yet there’s no compromise on appearance or ambience; the fire comes with a beautifully realistic coal fuel bed that appeals to those who love the classic bright glow of coals.
Accessorise
You can accessorise this fire with any of our stylish trim and fascia options to tailor the look. For example, many homeowners pair the Focus RS with a four-sided frameless trim for that minimalist hole-in-the-wall statement, while others might choose a more decorative fret to sit within a hearth; it’s compatible with both styles. Daily operation is effortless: choose between a remote control system or an easy slide control to ignite and adjust the flames.
Like its siblings, the Focus RS Plus BF is also 20% hydrogen blend ready, underscoring our commitment to future-ready technology. In summary, the Paragon Focus RS Plus BF is a top-tier choice for those seeking the highest efficiency and a sleek, modern look, while enjoying a genuine flame experience in a home without a chimney.
A Final Thought
Each glass-fronted gas fire in our 16″ range is a showcase of how far fireplace technology has come. In terms of design, these fires offer unparalleled versatility; you can opt for a contemporary frameless installation high on the wall or a traditional hearth setting with an elegant surround. There are models with different flame visuals, from classic coals to rustic logs, and a wide array of frame finishes and frets, ensuring your fire complements your interior style.
When it comes to performance, the living flame effects are so realistic and inviting that you get the cosy atmosphere of a real log fire at the push of a button, with generous heat outputs (3-4.4kW) sufficient to make any room snug on a winter’s night. All the while, energy efficiency is front and centre, thanks to our glass enclosure and advanced engineering. These fires achieve efficiencies of 80-95%, providing more warmth for less gas and lower heating bills.
They are also engineered for clean burning and future fuels, as evidenced by features such as catalytic liners in some models and readiness for hydrogen-blended gas. Finally, the installation flexibility cannot be overstated: whether you have a chimney, your room is large or small, or you’re doing a full renovation or just swapping an old inset fire. Balanced flue models let anyone enjoy a fireplace ambience in rooms without chimneys, and all models are designed to require minimal space and structural alteration, often only a 4″ recess, simplifying the fitting process.
