Chimney system and combustion air

Combustion air duct and chimney system

Every combustion, whether wood, gas or ethanol, requires oxygen and produces exhaust gases. For every type of furnace, a pipe for the combustion air (supply air / fresh air) and an chimney system are therefore an absolute must. The FeuerWerkstatt carries out this work 100 % cleanly and professionally.

Combustion air ducts must be insulated, passive houses or plus energy houses also require a tight shut-off damper on the façade.  If a furnace is not located on an external wall and there is no possibility of vertical ducting above the roof, the duct must be inserted into the concrete ceiling. This takes place at a precisely defined point in time, immediately after the reinforcement work. The actual chimney assembly then takes place directly after completion of the shell. Therefore: Involve us at an early stage when building a new chimney!

  • chimney system
