Single-flue block chimney
WATTI chimney blocks are Finnish-made and among the most environmentally friendly chimney elements on the market, with 95% of their raw materials sourced from metal and glass industry surplus.
The WATTI chimney is CE-approved and tested in Finland for Finnish conditions.
It’s a safe and simple solution for your home—no need for complex multi-layered pipes or insulation wool!
You can install the prefabricated chimney according to your preferences: from the top, side, or rear of the fireplace. The exterior can be finished to match your interior design.
The chimney blocks are manufactured in Oulainen, Northern Ostrobothnia.
WATTI-180 and WATTI-150 are the right choice for building a fire-safe flue.
Two- and Three-Flue Block Chimneys
If needed, you can install two or even three 150 mm or 180 mm blocks side by side using chimney assembly adhesive or S2-class renovation mortar.
The external dimensions for the double Watti-150+150 mm configuration are 700×350 mm, and for 180+180 mm, 760×380 mm.
The safety distance for both configurations is 50 mm.
Please note that the 150 mm and 180 mm blocks have different external dimensions, so they do not align well visually when combined.
TeräsWatti Steel Chimney
The stylish TeräsWatti is a seamless steel flue, exceptionally sturdy thanks to its larger-than-normal overlapping joints in the smoke pipes.
Additionally, it is very easy to install with clear instructions and installation videos.
We keep black and white colors in stock with a delivery time of about one week.
Other colors are also available with a slightly longer delivery time.
Accessories
WATTI chimneys are designed with easy installation and aesthetics in mind.
The cleaning door and smoke damper are stylishly shaped and made of stainless steel, with visible parts available in either white or black.
You can finish the chimney to match your interior using almost any ready-made plaster.
The chimney flashing on the roof is timeless, always attractive, and available in several RR colors.
With WATTI chimney products, you can effortlessly assemble a chimney tailored to your home’s dimensions.
