Scan-Line 805 Aqua has specially sealed stove glass, significantly reducing radiated heat in the room. The beautiful flame presentation and high 87% efficiency reflects the innovative development work. Give free rein to your imagination and exploit what they have to offer. The Scan-Line 800 aqua series comes with a safety valve for connection to existing systems. When connecting the stove, please ensure it has the ideal circulation pump flow rate of 140 litres/hour and that the existing system is equipped with a safety valve which activates if the water pressure exceeds 2.5 bar. The optional aqua kit prevents corrosion in the heat exchanger, as the return flow temperature is increased via the thermal three-way valve (bypass). The continual adjustment of a constant return water temperature ensures smooth combustion and optimal energy utilisation. The aqua kit is an optional extra and is not included in the stove price.
