The Holetherm single-wall flue gas exhaust system is certified according to the applicable European CE product requirements in compliance with NEN-EN 1856-2. Additionally, production is subject to periodic inspection by Kiwa Netherlands. New to our range are the elegant connection pipes between the appliance and the flue. These pipes feature a sleek design without conspicuous clamps and ridges and are available in plain and black stainless steel.

We call them Holetherm EW DECO because this decorative masterpiece deserves to be seen behind and above every stove!
