Froling log wood systems are available in 15 – 60kW output sizes, four model types: S2, S3, S4 and S5. The compact S2 (15-20kw) designed for smaller spaces, 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 (50-60kw) is further enhanced to provide maximum efficiency and controllability. The latest S5 (22-48kW) brings further innovation with improved combustion and latest LTC5000 software. The S2 and S5 are fitted with a flange to allow the addition 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.
