The Vitorondens 200-T features an affordable cast iron making it perfect for modernisation projects, high-operational reliability that has a long service life thanks to the Eutecplex heating surface, a cast section with flexible gaskets for durable sealing on the hot gas side, a downstream corrosion resistant stainless steel inox radial heat exchanger, a jet flow system for optimum heating water distribution. This is an easy to operate boiler, thanks to the Vitotronic control unit that features plain text and graphic display, so that you can have maximum control. As this is a System boiler, it directly heats your central heating system and hot water for a storage cylinder. PLEASE NOTE: Viessmann Flue Seals for Diesel Boilers (ZK02506) are required with every Viessmann diesel boiler flue system. Please contact KE KELIT Climate Control for more information
