Kratki NBU 11 Wood Fireplace

The Kratki steel firebox range pairs sleek and contemporary design with the most modern technology in fireplace combustion. Each unit boasts a sizeable glass window that provides a beautiful view of the flames once lit. For improved safety and performance, as well as an increased lifespan, the heat-resistant glass that Kratki uses is of the highest quality. Thanks to the specialised, air-wash glass cleaning system, the soot deposits on the fireplace glass are greatly reduced.

Considering that these fireplaces are built to last Poland’s harsh winters, Kratki’s built-in steel range is manufactured with thick, high-quality steel – which is reflected in the solid weight of each unit.

The burn chamber is lined with Kratki’s signature ceramics. When it comes to the choice of materials that can be used inside a fireplace chamber, these thick, heat-intensifying ceramics offer the best thermal properties available. With very impressive technical specifications, this closed-combustion fireplace is an excellent heating solution for anyone looking for a high-performance, modern, built-in unit.

The range provides primary and secondary combustion. By utilising both natural convection and radiant heating technology, these units offer a cleaner burn and the maximum heat output. Most units in this range also come with tertiary combustion. As an efficient, closed-combustion fireplace, most of the heat generated by the burning wood is released more effectively into the room for your comfort.

For improved safety and performance, as well as to increase their lifespan, the heat-resistant glass that Kratki uses is of the highest quality. Thanks to the specialised, air-wash glass cleaning system, the soot deposits on the fireplace glass are greatly reduced.

All Kratki’s wood-burning fireplaces come with a 5-year warranty. As a result, you can be confident that your fireplace has been designed with strength and durability at its very core and will last for many years to come.
