Why choose Kratki?

Technical specifications

Inside the fireplace chamber, Kratki’s signature ceramic lining enhances both combustion efficiency and long-term durability. These heat-intensifying ceramics deliver exceptional thermal performance, supporting primary and secondary combustion for a cleaner burn and maximum heat output. By maintaining consistently high temperatures within the combustion chamber, the ceramics make the fireplace easier to operate, improve heat delivery, and significantly reduce soot buildup in the flue system. Lining the chamber with ceramics provides the highest level of protection to the steel structure, extending the lifespan of the fireplace.

The body of the fireplace insert is built from high-quality, thick steel, ensuring exceptional resistance to high temperatures. Each unit is precision-welded in a shielded noble gas environment for superior structural integrity and airtight performance. Using advanced laser-cutting and CNC bending technology, every steel component is crafted with accuracy and consistency to guarantee a perfect fit and long-lasting durability.

Kratki’s signature flue connection design stands out for strength and versatility. The large and thick cast-iron spigot provides not only exceptional structural strength, but also allows for flexible flue routing. The two-part rotating spigot can be adjusted to accommodate various flue directions – from the standard vertical outlet to a 90-degree rear exit – making installation simpler and more adaptable to different site conditions.

A large, black-edged design glass door frames the flames beautifully, while Kratki’s superior heat-resistant glass and air-wash system help keep the viewing window clear. For improved safety and performance, as well as to increase their lifespan, the heat-resistant glass that Kratki uses is of the highest quality.

Kratki’s signature fireplace grate design is engineered using thick cast iron, featuring re-enforced ribbing and multiple bends to maximise strength, durability, and long-term performance.

A robust steel removable ash box ensures easy cleaning and everyday convenience.

A single air control allows precise regulation of primary, secondary and tertiary airflow. The added tertiary combustion improves efficiency and provides a cleaner burn.

Direct fresh air system can be used where only outside air is used for supply to the fire – built-in external air inlet 125mm diameter.

A set of adjustable feet allow for the fireplace to be easily set level.

Built to deliver lasting warmth and reliability, Kratki wood-burning fireplaces are backed by a 10-year warranty, reflecting Kratki’s commitment to quality, performance, and longevity.
