Available with optional pellet flange - Pellet unit can be added any time.

The S4 Turbo F with pellet flange (up to 40kW) firewood boiler is the ideal solution for people who are burning firewood and pellets: the pellet unit can be retrofitted at any time. What you then get is the SP Dual, a dual fuel boiler that can automatically switch between firewood and pellets. Thanks to its modular design, the S4 Turbo F boasts important advantages even before it is put into your boiler room. It is so compact that installing it is child’s play, even in confined boiler rooms.
