Effectively use natural heat

It is cold and ugly outside and you want to bask and to cosy up to the fireplace inside your house but the fireplace is ineffectual. This depends on the fireplace itself because 90 percent of the heat escapes unnoticed. The Wotan heating coffer uses the cooled off room air. Additionally the air will be heated by the open fire and streams through the air escape of the heating coffer
Every Wotan heating coffer has high heat-resistant glass (Neo-Ceranglas). You have the opportunity to an unattended beaconing.
Your Wotan heating coffer can be built by your personal and individual wishes. The Wotan heating coffer offers up to 50 percent more heat output and a controllable burn off with a reducing of the combustible material and the ash residue.
