Why choose Kratki?

Technical specifications

Bioethanol fuel gives a clean burn with no harmful emissions. Kratki bioethanol fireplaces can therefore be used without any flue pipes and offer an easy installation solution. These fireplaces provide a beautiful flame and bring atmosphere to your space. While these bioethanol fireplaces do provide some heat, it’s not enough to be felt in a large area. For heating purposes, they are well suited for smaller spaces such as bedrooms or smaller apartments. The Kratki bioethanol range has the German TUV certification. Never add fuel to a bioethanol fireplace when the unit is hot. Wait for it to cool before refilling.
