Froling S4 Turbo Log Boiler

The Froling S4 Turbo log boiler allows you to burn half-meter 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 log boiler 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 carbonization 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 optimized 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.

The RBG 3200 room console gives you a full overview from your living room. It is extremely easy to read off all the important values and status messages and you can change settings at the push of a button.
