Description
The Flavel Calibre is a high-efficiency inset gas fire designed to deliver strong heat performance, impressive fuel economy and a clean contemporary look suitable for a wide variety of fireplace settings. Built for homes wanting a modern gas fire without major installation changes, the Calibre fits neatly into a standard 16″ × 22″ inset opening while offering a deep, satisfying flame picture and a realistic, full-depth fuel bed.
With a powerful heat output of up to 4.0 kW, the Calibre provides dependable warmth for medium-sized living spaces. Its deep coal-effect bed creates vivid, natural flame movement, giving the appearance of a traditional open fire while benefiting from the higher efficiency expected of today’s gas fire designs. The fire’s clean fascia styling allows it to work well in both modern and classic interiors.
Available with a choice of control types — including manual, slide and remote depending on the selected model — the Calibre offers flexibility for different households. Many models in the Calibre range are classed as high-efficiency glass-fronted fires, helping reduce heat loss and improve running costs while still providing a bright and engaging flame picture.
The fire is suitable for Class 1 and Class 2 flues, widening its installation options and making it a strong choice for homeowners upgrading from older inset gas fires. As with all Flavel gas models, safety is at the core of its design, with a Flame Supervision Device (FSD) and Airwatch System included for safe and reliable operation.
Blending efficiency, comfort and aesthetic appeal, the Flavel Calibre is an excellent option for anyone looking for a powerful, stylish and economical inset gas fire for their living space.
