Froling firewood boilers boast superior practical use, sturdiness, and safety, resulting from decades of experience, and are available in 15 – 60kw output sizes, three model types: S1 Turbo, S3 Turbo, and S4 Turbo. The compact S1 (15-20kw) is designed for smaller spaces, and the S3 (20-45kw) offers top-quality boiler technology for a mid-range price. It contains many features that you would otherwise only find in high-end firewood boilers.

The S4 (22-60kw) is further enhanced to provide maximum efficiency and controllability. The S1 and S4 (Up to 40kw) are fitted with a flange to allow the addition or retrofit of a pellet module to allow dual fuel use. Each boiler can be loaded with half-metre firewood easily from the front. Strong steel guards protect the loading chamber and keep it clean. The boiler control system manages the induced draught fan, flue gas, and boiler temperature monitoring, ensuring efficient combustion. The S1 now has the option of an Electrostatic Precipitator to reduce further the particulate emissions.
