Crafted to fit into a standard 16” fireplace opening, this modern convector fire delivers the perfect balance of style, performance, and economy, making it an outstanding upgrade for any UK home.
A Perfect Fusion of Design and Efficiency
The Adore 400 HE has been carefully developed for today’s energy-conscious homeowner who values both form and function. Its advanced convector system and glass-fronted design ensure that the majority of the heat is directed back into the room, rather than lost up the chimney. With a heat output of up to 3.4kW and an impressive efficiency rating of 83.1%, this model provides an economical way to keep your home warm and inviting all year round.
Realistic Log Effect and Mesmerising Flame Display
At the heart of the Adore 400 HE lies a realistic log-effect fuel bed combined with flat bed burner technology, designed to mimic the authentic charm of a real wood fire. The flames dance naturally across the logs, creating a deep and visually stunning flame picture that instantly transforms the atmosphere of any room. Whether you’re relaxing alone or entertaining guests, the fire’s warm glow and refined flame movement add a touch of luxury to every occasion.
Effortless Control at Your Fingertips
User convenience is at the core of the Adore 400 HE’s design. Its innovative Slide Control system is discreetly integrated at the top right-hand side of the fire, allowing you to light and adjust the flames easily without bending or removing the fascia. The intuitive control lever provides smooth, precise operation, ensuring your fire looks and performs beautifully with minimal effort.
Designed to Fit Standard Fireplaces
Thanks to its versatile design, the Adore 400 HE can be installed into a standard 16” fireplace back panel opening, making it ideal for both contemporary and traditional interiors. It’s suitable for use with Class 1 (brick chimney) and Class 2 (5" prefabricated flue) systems, providing a practical solution for a wide variety of properties. The full-depth convector design ensures maximum heating performance while maintaining a compact overall footprint.
Built to Last with Quality You Can Trust

Manufactured by Adore Fires, a respected brand under Hearth Products Ltd, the 400 HE showcases exceptional craftsmanship and reliability. Every appliance is tested to meet strict British and European safety standards, ensuring long-term performance and peace of mind. Complete with a 3-year manufacturer’s warranty, this fire offers the perfect combination of premium build quality and outstanding value.
Why Upgrade to a Glass-Fronted Gas Fire?
Unlike open-fronted models, glass-fronted high-efficiency fires retain significantly more heat, helping to lower energy costs while keeping your living area cosy. The Adore 400 HE’s sealed glass panel prevents heat loss, ensuring maximum warmth and comfort without compromising on the beauty of real flames.
