Why choose Kratki?

Technical specifications

The Kratki Jas fireplace pairs minimalist, contemporary design with the most modern technology in fireplace combustion. This wood-burning fireplace is sure to capture attention with its sizeable glass window that provides a beautiful view of the flames once the fire has been lit. With very impressive technical specifications, this closed-combustion fireplace is an excellent heating solution for anyone looking for a high-performance, modern unit at an economical price point.

While the Kratki Jas can be installed as a built-in fireplace it can, as an alternative, be installed on a ledge as a countertop, freestanding fireplace.

Considering that Kratki fireplaces are built to last Poland’s harsh winters, this Jas firebox is manufactured with thick, high-quality steel – which is reflected in its solid weight.

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.

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.
