Klimosz Ling Duo

LING DUO is an automatic two-furnace boiler, adapted for automatic burning of solid fuels, such as pea grade coal, pellets and – as substitution – oats grain (oats grain only in 15-35 kW boilers), and for “manual” burning of fuel in larger pieces (wood, hard coal, waste paper). The boiler is made of high quality 8 mm thick steel and fitted with a modern and easy-to-operate boiler regulator Recalart Economic Premium. Tests carried out on the boiler at the “OTGS” Institute of Power Engineering, Łodź, have proved its high efficiency, which may even be as high as 89%, and low emissions of noxious substances. LING DUO boilers with the power capacity of 15, 25 and 35 kW have been unified as one version, which in practical terms means that the storage tank can be switched from the right to the left side.
