MAXIMUM ENERGY USE

The Lucy Tunnel Wood Burning Fireplace Insert – 12kW is a contemporary double sided fireplace designed for maximum performance, modern style, and efficient heating. This double sided wood burning fireplace offers more efficient combustion and longer temperature retention thanks to the TERMOTEC combustion chamber lining, a heat-accumulating material that raises the temperature in the combustion chamber.

Fuel particles are burned thanks to two deflectors that extend the exhaust gas path. This process also increases combustion efficiency and ensures better energy utilization, making this energy efficient fireplace insert ideal for UK homes while minimizing harmful emissions into the atmosphere.

Air is supplied to the wood burning fireplace insert UK market model exclusively from the outside, thanks to the built-in 125 mm air intake. Air is regulated using a single damper located below the door, eliminating errors due to improper use. The entire mechanism operates very quietly and reliably.

The contemporary double sided fireplace insert uses a dual combustion chamber ventilation system. Primary air, which facilitates wood ignition, is supplied under the grate. Additionally, this wood burning stove insert features a clean glass system (air curtain), which means air is delivered directly to the glass through a system of channels located on the sides of the fireplace.

This delivers oxygen to the upper part of the combustion chamber, where gases produced during wood combustion are burned, further reducing harmful CO emissions into the atmosphere. This precise air supply system makes it a high efficiency wood burning stove and a reliable steel fireplace insert.

 

ECOLOGICAL COMBUSTION

This modern wood burning fireplace insert meets the requirements of Ecodesign and the BimSchV 2 standard, which sets maximum CO emissions.

As a low emission wood burner, it provides environmentally conscious heating without compromising on warmth or visual appeal. It is an excellent fireplace insert for wood burning fireplace upgrades and modern renovations.

SAFETY AT THE HIGHEST LEVEL

The front of the insert is equipped with heat-resistant ceramics that can withstand temperatures up to 660°C. The glass offered is certified for quality and safety.

The special perforated handle design protects against excessive heat, ensuring high comfort of use. The body and front of this built in wood burner are resistant to high temperatures thanks to the use of high-quality steel.

Excellent tightness is achieved thanks to solid welds made in a noble gas shield. The steel elements are laser-cut using modern equipment and then bent on CNC bending machines.

COMFORTABLE USE

This double sided fireplace features a specially profiled bottom plate made of TERMOTEC material, allowing for a deeper combustion chamber and greater wood capacity.

The removable grate and ash pan make it easy to keep the insert clean. The clean glass wood burner system reduces soot buildup. An air curtain separates the glass from the firebox, preventing it from becoming dirty and releasing more heat into the room.

Adjustable feet allow you to compensate for uneven floors and level the insert. This model is equipped with a movable exhaust outlet, eliminating the need to purchase additional elbows during installation. The angle of the insert’s connection to the chimney can be easily adjusted.

 

MODERN DESIGN

The contemporary double sided fireplace insert is equipped with two doors: one front and one in the rear (instead of a rear wall), allowing heat to radiate in two directions. This makes it a perfect double sided fireplace solution for installation between adjacent rooms such as a living room, dining room, or bedroom.

The contemporary double sided fireplace insert is equipped with a single decorative glass pane, giving it an elegant and modern look. This visually enlarges the front of the insert and highlights the fire beautifully.

This contemporary fireplace insert model combines style and function, making it the ideal contemporary double sided fireplace for homeowners seeking a premium heating feature.

The inset door has a convenient handle and is lined with black Termotec for a luxurious finish.
