The Highlander-8 has a superb air wash system designed to keep the glass clean by diverting a warm flow of air directly over the surface of the glass. Each door has its own primary air controls. These control the amount of fuel being burnt and can also be closed down for overnight burning of fossil fuels. With a heat output of 7 - 8 kW maximum the Highlander-8 will heat a medium to large room. The grate mechanism can be adjusted for burning wood or other solid fuels including: peat, coal and coal briquettes. There is a choice of boiler, which is available in steel or stainless steel if required to connect into a direct hot water cylinder. This takes the place of the rear fire brick and can be installed at the factory or at a later date if required. The Highlander-8 is available with black, brass or polished steel knobs and is finished in black metallic paint.
