Wöhler – efficient and advanced solutions for the chimney industry

When it comes to measuring, inspecting and cleaning chimneys, our German partner Wöhler is an indispensable link. Their equipment is reliable, innovative and designed to meet all the needs of chimney sweeps during the heating season.


Wöhler’ s wide range of products includes flue gas analysers, dew point indicators and leak testers. Ensure accurate measurements and identify potential problems before they become serious.

Flue gas analysers: are a key tool for chimney sweeps and heating systems. They can accurately measure the composition of the flue gases, allowing you to assess the combustion efficiency and identify any problems in the heating system. Measuring the concentrations of different gases such as carbon monoxide (CO), carbon dioxide (CO2), oxygen (O2) and other impurities allows you to take appropriate measures to improve the performance of your heating system and reduce pollution.

Dew point indicator: is essential to prevent condensation of flue gases inside the chimney. When flue gases cool, they can condense and form harmful moisture that can cause corrosion and damage to the chimney. The dew point indicator helps chimney sweeps to determine whether the conditions in the chimney are suitable to prevent condensation problems.

Leak tester: is an indispensable tool for checking the leak tightness of a chimney. Leaks in the flue ducts can cause flue gases and carbon monoxide to escape into the room, which is extremely dangerous to human health and can even cause fires. The leak tester allows you to detect potential leakage problems, so you can take the necessary remedial action in time – for the safety and efficiency of your heating system.

With the help of video inspection cameras and mirrors, you will be able to easily detect any obstructions or damage to the flue or chimney. Detecting problems early can prevent serious problems.

Video inspection cameras: allow a detailed examination of the inside of the chimney, including those parts that are difficult to access. This tool can detect cracks, damage, soot build-up, deposits or other problems that could hinder the proper functioning of the chimney. By checking in time, you can prevent potential problems and reduce the risk of fire or flue gas leaks.
