The 350 GreenSwitch™ is a room heating stove with thermostatic boiler. It has an operating range of 14.7kW/h but gives only a modest 3.6kW/h to the room and a generous 11.1kW/h (38,006 Btu) to water. These figures are based on wood-burning and will be slightly higher when burning mineral fuel.

The 350 GreenSwitch™ is equipped with a control (the Green Switch) that adjusts the airflow to maintain the most efficient combustion whether burning wood or mineral fuel. Its large capacity firebox makes it a versatile woodburner.

Like the rest of the 300 series it fits into a standard fireplace, however a depth of 372mm must be created to allow for its larger capacity firebox.
