Cast Iron Wood Burning Fireplace Kratki NBC, 7kW

Panoramic fire and modern looks from a European leader.

The Kratki NBC 7 is a compact steel fireplace insert with three-sided glazing, created by the Polish manufacturer Kratki – an established name in heating solutions since 1998.

It brings together clean, contemporary aesthetics and excellent heating performance to turn the living fire into the central accent of the interior. Thanks to the panoramic view from three sides, the flame is visible from almost any point in the room, while the A+ energy efficiency class ensures that beauty goes hand in hand with economy.

The model is suitable for efficient heating of rooms of up to about 100 m².

The body is made of high-quality steel – all elements are laser-cut and bent on CNC machines, and the welds made in a shielding gas environment ensure complete tightness and a long life for the appliance.

The combustion chamber is lined with the heat-accumulating material TERMOTEC, which raises the combustion temperature, retains heat longer and ensures cleaner, more efficient burning of the wood.

The triple air supply system and the "clean glass" system (air curtain) keep the panoramic panes transparent, and the air supply is controlled with a single regulator – simple and with no risk of incorrect adjustment.

The door opens smoothly upwards on a guillotine-type mechanism with a safety lock, and the three-sided glazing lets you open just one side for convenient wood loading without having to lift all the panes.

The front is protected with heat-resistant ceramics withstanding temperatures of up to 660 °C, and the option of connecting to an external air duct makes it suitable for modern, well-insulated homes as well.

The removable grate and ash pan reduce maintenance to a few minutes.
