The S3 Turbo offers top quality boiler technology for a mid-range price. It concentrates on the most important points and includes a lot of features, which are otherwise only found in top of the range firewood boilers. The S3 Turbo can be loaded with half-metre firewood easily from the front. Often the boiler only needs to be filled once for the entire day. Strong steel guards protect the loading chamber and keep it clean.


With its patented, cylindrical high temperature swirl combustion chamber, the S3 Turbo delivers excellent combustion values. The generous dimensions of the combustion zone guarantee low emissions. The efficiency optimisation system (WOS) makes it easy to clean the heating surfaces from outside using a lever mechanism. The carbonisation gas extraction system also prevents any gas escaping when topping up.


The primary and secondary air settings are adjusted by the technician during commissioning. The function-monitored induced draught fan enables the system to adjust to different operating statuses. This means the system has excellent output adjustment with full operating safety. The speed-regulated induced draught fan ensures constant high quality combustion, the carbonisation gas extraction system prevents any smoke from escaping even while topping up.


The S-Tronic controller in the boiler controls the induced draught fan and offers the option of connecting a storage tank loading pump and a heating pump. Flue gas and boiler temperature monitoring ensures efficient combustion. Any regional regulations requiring the use of weather-activated controls should be observed.
