Hydrotherm adds two new sizes to its KN-Series of condensing cast-iron boilers: the KN-16 and KN-26. The KN-Series boilers combine up to 99% efficiencies with durability of cast iron through the Hydrotherm proprietary HeatNet control platform. The boilers are made from more than 80% recycled material, are LEED-certified, and operate with low NOx and CO2 emissions.
