Efficiency and conveniencepar excellence

Future-proof through biogas

Condensing technology fromViessmann is future-proof, becausebiogas, made from sustainable rawmaterial, can replace natural gas,step by step. With their LambdaPro Control, gas fired condensingboilers from Viessmann arealready prepared for the use ofbiogas.

Enjoying heating convenience

Wall mounted gas fired condensingboilers from Viessmann featurecompact dimensions and a quietoperation, making them ideal forinstallation near the living space.Their low outlay creates a firstclass price/performance ratio; andtheir special heating convenienceregarding central and DHW heatingmake them highly desirable.

Consistently reliable quality

Highly alloyed stainless steel isused for all condensing boilers andheat exchangers from Viessmann.This way, you can count on theirlasting operational reliability andtheir long service life.

Inox-Radial heat exchanger madefrom stainless steel

Even though fossil fuel resourcesare finite, in future we will not beable to generate heat without gas.So, this calls for greater efficiencyto reduce gas consumption.

When converting gas into heatingenergy, nothing rivals the efficiencyof proven gas condensing technology.It can achieve an energy utilisationof up to 98 %.

The outlook for the environment

is good

Condensing technology reducesenergy consumption and CO2emissions significantly, becauseefficient condensing boilers fromViessmann also utilise the latentheat in the flue gas and return thisheat to the heating system.

Designed suitable for recycling

All Viessmann products aredesigned with recycling in mind.The equipment is easy to dismantle,and all components used are clearlyidentified according to materialtype.

This ensures consistently highenergy efficiency and offerssecurity for the future in liberalisedgas markets and where gases ofbiogenic origin are mixed withnatural gas.

High DHW convenience

The combi versions of the Vitodens 200-W are equipped with a DHW standby function. This ensures that DHW is alwaysavailable at the required watertemperature.

With the Vitodens 200-W,Viessmann offers a wall mountedgas fired condensing boiler with anexemplary price/performance ratio,excellent heating and DHWconvenience, compact dimensionsand a timeless, elegant design.

Standard efficiency

up to 98 % (Hs)/109 % (Hi)

The Vitodens 200-W consumes less energy because it also utilisesthe latent heat in flue gas. Result: A standard efficiency up to 98 % (Hs)/109 % (Hi). It’s clear thatyou’ll reduce your heating costsand be more environmentallyfriendly in the process.

Continuous efficiency

Stainless steel is the only choicewhere economy and a long servicelife are required. For this reason,the Vitodens 200-W is equippedwith a stainless steel Inox-Radialheat exchanger. It offers therequired reliability and ensurespermanently high condensingefficiency.

Extended modulation range

The new MatriX cylinder burner is the result of both in-housedevelopment and manufacture, it offers an extended modulationrange of 1:4. The Lambda ProControl combustion controller has now also been integrated. It automatically matches thecombustion to changing gas types.

The Vitodens wall mounted gasfired condensing boiler offersmuch more than the immediatelyobvious benefits that are importantto you. You also profit fromViessmann’s resolutely modulardesign applied to all wall mountedequipment.

Simple and time-saving

All wall mounted units are modular and offer a high degree of continuity and uniformity ofcomponents. For your local heatingcontractor, this begins with thesimple installation of the wallmounted boiler with standard,uniform fixings and installationaids. All wall mounted units havethe same type of Aqua-plate withthe multi connect system, ensuringsimple and fast installation. Allwater routes are located at the backof the equipment. As a result, allparts can be accessed and replacedfrom the front, so no need to removeit from the wall. For users, thismeans: A reduction in maintenancecosts.

Due to the easy access, there is noneed to worry about serviceclearances. It is possible to installthe boiler in a corner or a recess.
