FRÖLING S4 TURBO (F) / SP DUAL


The innovative, wood- or pellet-burning SP DUAL water boiler is available with capacities ranging from 15 to 40 kW and combines state-of-the-art wood-burning technology with the convenience of a pellet-burning system. Wood is ignited with the help of residual embers, manually or automatically, by means of the pellet burner. Once the wood has burnt down, the pellet burner is activated automatically if more heat is needed before fuel added. Even with its high efficiency rates and the added convenience of automatic ignition, the SP DUAL features low emissions and energy costs.
