VITODENS 200-WHigh output gas fired system boilers forcommercial applications.45kW, 60kW, 80kW, 105kW. Cascade up to 420kWTheVitodens 200-W high specification boiler is one of themost efficient and quietest condensing boilers in this sector.It is now available for commercial applications of up to420kW – good news if access is difficult, floor space islimited, if you prefer the reassurance of having more than oneboiler running as a back-up - or if you want all the features ofthis great wall-hung gas condensing boiler2, 3 or 4 boilers can be cascaded in various configurations,giving a maximum output of 420kW. Simply tell us yourrequired output and we can supply all the components youneed for the best cascade combination for your project – seepage 5.KEY FEATURES:Gross efficiency up to 98%NOx credit rating 4 (
VITODENS 200-WFeaturingViessmann’s unique energymanagement systemIntelligent Lambda Pro gas management system foroptimum efficiency and performanceThe Lambda Pro is designed to work efficiently irrespectiveof gas quality – a factor which will become increasinglyimportant as international gas supplies become less reliable.The Lambda Pro combustion controller works alongside theburner to constantly monitor the air to gas ratio. Instead ofthe gas/air mix remaining fixed from commissioning, the mixis self adjusting as required, to maintain optimum boilerefficiency in relation to the gas quantity – in a similar way tothe fuel management system in a car engine.The control also replaces the traditional gas valve control andchanging to LPG takes just a few seconds – with no changingof any parts.Modulating MatriX pre-mix burnerDeveloped byViessmann, the stainless steel MatriX pre-mixburner burns with thousands of tiny flames instead of onelarge one, to distribute heat cleanly and efficiently to the heatexchanger.With a modulation range of 1:4 the heat demand is optimisedand maximum efficiency levels are achieved.The extremelylow NOx and CO emissions meet or exceed all national cleanair regulations and guidelines.The stainless steel MatriX mesh ensures long term reliability.Inox Radial heat exchangerAs with allViessmann wall-hung boilers, theVitodens 200-WfeaturesViessmann’s unique stainless steel heat exchanger,designed for long term reliability, high performance and selfcleaning.The design of the heat exchanger ensures high heat transferthrough laminar hot gas flow across defined gaps. Highcorrosion resistance is maintained by the use of high gradestainless steel 1.4571 and thick walls.This component is soreliable that it comes with a 10YEARWARRANTY againstcorrosion.Advanced controlsTheVitodens 200-W is loaded with features and functions tomake installation, maintenance and servicing easy.Theseinclude in-built software for remote data communication andmonitoring, additional heating circuits, a solar/heat pumpinterface, safety monitor sensors and automaticcommissioning functions.Weather compensation controlsTheVitodens 200-W is available with optional weathercompensation controls (theVitotronic 200). Constant, smalladjustments in the boiler flow temperature, in response tochanges in the outside temperature, enable the boiler to runcost effectively and efficiently at lower temperatures,condensing for longer.This results in additional fuel savingsof up to 15%.3
