S4 Turbo F

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. Thanks to its modular design with just a single exhaust pipe, it is particularly easy to retrofit a pellet unit at any time.
