Flavel Diamond HE Wall Mounted Gas Fire – Sleek, Efficient and Designed to Impress
The Flavel Diamond HE is a striking wall-mounted gas fire that brings together modern design and high performance in a compact, space-saving format. Perfect for contemporary interiors, this ‘hole-on-the-wall’ model is the ideal centrepiece for living rooms, dining areas, and open-plan spaces where style, comfort, and energy efficiency are top priorities.
With a bold, angular fascia in a two-tone finish, featuring a textured black outer frame and contrasting satin silver inner trim, the Diamond HE stands out as a design statement. Its clean lines and glass front give it a sleek, streamlined appearance, creating the illusion of a floating fire that blends beautifully into any feature wall.
But the Diamond HE is more than just a pretty face. With a direct heat output of 3.4kW and an impressive efficiency rating of 84.3%, it provides excellent warmth while using less gas, making it a smarter choice for both comfort and cost. The glass-fronted design helps to retain heat within the room, rather than allowing it to escape up the flue, which is often the case with traditional open-fronted fires.
Inside the fire, you can choose your preferred look with a realistic coal-effect fuel bed for a classic aesthetic or opt for the sleek pebble set for a minimalist, modern feel. The gently glowing flames dance across the fuel bed behind the clear glass panel, creating a warm and calming atmosphere that enhances the ambience of any room.
The Flavel Diamond HE is suitable for installation into Class 1 (real chimney) or Class 2 (pre-fabricated 5") flues, providing flexibility for many types of UK homes. Its slimline profile and wall-mounted configuration make it especially well-suited to properties where floor space is at a premium, or where a more contemporary fireplace solution is desired.
No additional ventilation is normally required, and the fire comes equipped with essential safety features, including a Flame Supervision Device (FSD) and Airwatch System. These integrated technologies automatically shut off the gas supply if the flame is unexpectedly extinguished, ensuring safe operation at all times.
With its blend of modern styling, efficient performance, and built-in safety, the Flavel Diamond HE is a smart and stylish alternative to conventional gas fires—designed to make a lasting impression while keeping your home warm and inviting.
