The ACR T550 ECO-BG 5kW Inset Multifuel Stove is a contemporary inset stove that combines bold modern styling with efficient everyday heating performance. Designed with a sleek black glass door, clean lines and a wider firebox, it offers a more dramatic and design-led take on the traditional fireplace while still delivering the practicality needed for modern homes.
A major part of the T550 ECO-BG’s appeal is its visual impact. The wider firebox and expansive viewing window create a broader, more uninterrupted view of the flames, helping the stove become a true focal point in the room. The black glass door adds a premium contemporary finish, while the option of a 3-sided or 4-sided frame allows the final installation to be tailored to different fireplace designs. Whether used in a classic chimney breast or a more modern setting, the stove brings a crisp and refined look.
The T550 ECO-BG is also designed for straightforward installation. A discreet convection outer box helps the insert sit neatly within the fireplace opening, supporting a cleaner and more integrated finish across a wide variety of installation styles. As a multifuel stove, it can burn logs up to 40 cm as well as approved smokeless fuels, giving customers more flexibility in how they use it. It is also DEFRA exempt, allowing wood to be burned in smoke controlled areas.
In performance terms, the stove delivers a 5 kW nominal output, with an output range of 3 kW to 7 kW. It achieves 75.4% gross efficiency and 82.9% net efficiency, carries an A+ energy rating, weighs 75 kg, and uses a 125 mm flue diameter. A constructional hearth is required because hearth temperatures exceed 100 degrees.
