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 WOS is optional for models 18 and 28, and it comes as standard from model 36 on. 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.

The S4 Turbo allows you to burn half-metre pieces of firewood even from an output of 15 kW. Fröling has developed the tested cylindrical combustion chamber shape further and sets new standards. The robust construction and the use of silicon carbide as a material for the high temperature combustion chamber enable a longer service life.

Load the boiler, light the fuel, close the door and that's it. Heating with the new S4 Turbo from Froling is so easy! If you would like to make it even easier to operate, you will love the optional automatic ignition device. 

The speed-regulated induced draught fan ensures constant high quality combustion, the special carbonisation gas extraction system prevents any smoke from escaping even when topping up. WOS as standard! You can have a lever on the left or the right for easy cleaning of the heating surfaces from outside, while keeping efficiency at maximum levels. 

Froling is pointing the way ahead with the newly developed S 3200 control system. The control unit is optimised to fit requirements, and along with an individually adjustable viewing angle, it ensures that all operating statuses are clearly shown. 

The clearly-structured menu makes the system easy to operate. It is simple to select the important heating and hot water functions using the function keys. The Froling bus system makes it possible to install expansion modules in any location, and electrical wiring is kept to a minimum.
