Firewood Boiler S1 Turbo

Froling's new firewood boiler (15 - 20 kW) combines all the features of a state-of-the-art biomass combustion system. The speed-regulated induced draught fan ensures constant high quality combustion and the carbonisation gas extraction system prevents flue gas from escapin, even when topping up. The new S1 Turbo stands out for its high efficiency and long refilling intervals, combined with low emissions and low energy consumption.

The new air duct concept in Froling's S1 Turbo firewood boiler automatically regulates the heating air, primary air and secondary air with a single actuator.
