Firewood and pellet boiler

NEW! S5 Dual

Two systems perfectly combined

The S5 Dual firewood and pellet boiler combines two perfect systems – it meets all the requirements for firewood and pellet fuels in two separate combustion chambers. Highly efficient and convenient – the S5 Dual boasts low emissions and energy costs.


The new LTC 5000 control system with 7″ glass touch display offers even more options when it comes to controlling the boiler. The swivelling flue pipe connection makes adapting to different types of installation possible, considerably facilitating installation. Optionally, an integrated particle separator ensures even lower emissions and fulfils the highest requirements for environmental friendliness.


Proven features such as efficient carbonisation gas extraction, the speed-controlled induced draught fan, long refilling intervals and low power consumption make the S5 Dual a solution that is as economical as it is convenient. The S5 Dual also offers important advantages when installed in the boiler room: The compact design means that installation is child’s play, even when space is limited.

Pellet unit can be retrofitted at any time

Froling offers a flexible solution for people who may want to use pellets in future: the S5 Turbo comes with a pellet flange as standard, which means that the pellet unit can be retrofitted at any time. This is supplied fully insulated and ready to plug in.
