Foreword

2/3

When it comes to convenient heat generation with natural gas, Viessmann has various technologies to offer that can satisfy a wide range of demands: whether for new build or modernisation, a flat or a detached house, or even for major housing developments.

Condensing technology protects the climate and the environmentAll our boilers meet the requirements demanded by efficient condensing technology, i.e. 98 percent or more of the energy spent is converted into heat. With such unbeatably high levels of efficiency, everyone who uses a gas condensing boiler is making a positive contribution to protecting the climate and the environment.

Futureproof heating technology protects resourcesViessmann gas condensing boilers are already prepared for the future. Thanks to their combustion controller, these boilers adjust automatically to various gas types – including biogas mixtures. As a result, these heating systems meet the demand for sustainable heating technologies that are able to conserve natural resources.

Choosing gas central heating also means there's no need for a fuel store in the house. These compact appliances use space efficiently, leaving you with extra space in your utility room or cellar.

Solar technology uses free solar energyEvery new heating system, nowadays, should also be able to work with solar collectors to benefit from free solar energy. All Viessmann boilers are set up for this right now.

Viessmann system design guarantees that all components work together perfectly, right down to the convenient control unit – even via the internet using an app that does everything you could ask of it.

This brochure provides information on our current range of appliances and plenty of other details – from accessories and service to finance packages.

Introduction

How condensing technology works:

Viessmann gas boilers and condensing technology turn

up to 98 percent of the energy spent into heat. Through

the condensation of water vapour contained in flue gas,

additional heat is released which is returned to the heating

system. This improves efficiency, cuts heating bills and

reduces the environmental impact.

More effective, more economical with lower emissions –

advanced gas condensing technology from Viessmann

Viessmann works continually to develop new,

environmentally responsible solutions, resulting in eco-

friendly, cost effective and efficient heating systems.

6/7

In Germany alone, there are still around two million heating systems in use today which are more than 25 years old. Their owners are often completely unaware of how much money they are wasting unnecessarily on energy, which is pointlessly burned up and goes out of the chimney as unused heat. Furthermore, these old systems have an impact on our climate through unnecessary CO2 emissions which contribute to global warming.

By replacing these floorstanding boilers with highly efficient condensing boilers, consumers can save a lot of energy – up to 35 percent when used alongside solar technology. This would translate into ten percent of Germany's total energy needs, with annual CO2 emissions simultaneously being reduced by 54 million tonnes.

Central heating backup with solar technologyFree energy delivered by the sun is still not used often enough for central heating backup and DHW heating. For modernisation projects, combining a heating system or new boiler with a solar thermal system should be a given.

Saving energy and money with condensing technologyWith conventional heating technology, hot exhaust gases escape up the chimney unused. Condensing technology uses the heat latent in these gases and turns almost all of it into heating energy.

Cost-benefit analysis for your home

The Viessmann Building Energy Economy Check provides

all the answers to key questions about modernising your

heating system. You only need to enter a few details via your

PC or tablet.

Replacing old boilers saves up to 35 percent on energy bills

Good reasons for modernising heating systems using efficient gas condensing technology.

To do this, Viessmann equips its condensing boilers with stainless steel Inox-Radial heat exchangers. These cool the flue gases before they are routed into the chimney, to the extent that the water vapour contained in these gases is deliberately condensed. The additional heat released is transferred into the heating system.

With this technology, condensing boilers convert up to 98 percent of the fuel into heat, making them particularly energy efficient. This function not only saves valuable energy, but also protects the environment through significantly reduced CO2 emissions.

The ultimate wall mounted boilerThe Vitodens 300-W wall mounted gas condensing boiler can be used both in modernisation projects and in new build. Its output is 1.9 to 35 kW. The MatriX gas burner stands out due to its reliable and efficient operation, as well as its clean combustion and quiet operation. At the heart of the Vitodens 300-W is the stainless steel Inox-Radial heat exchanger. It converts the energy spent into heat with almost no loss.

Wide modulation range The wide modulation range of 1:10 reduces the number of times the burner cycles when heat demand is low. This optimises the pause times and results in a particularly long service life for the ignition unit. The low fan speed reduces combustion noise.

Wide range of applicationsThe Vitodens 300-W has output ratings that make it the ideal wall mounted gas condensing boiler for a wide range of applications:

modernisation of heating systems in apartments or in detached houses with high demands for central heating and DHW convenience

systems where boiler space is limited or the installation location is restricted (e.g. roof space)

replacement of existing floorstanding boilers in systems of different type, including those with several heating circuits and underfloor heating

Personal DHW convenienceFor convenient provision of hot water, there are flexible cylinder solutions available for the Vitodens 300-W. The Vitocell 100-W DHW cylinders, with capacities of 120 and 150 litres, are especially space efficient. They are installed immediately below the condensing boiler. Their Ceraprotect enamel coating ensures a long service life. Versions with high efficiency thermal insulation reduce radiation loss to a minimum. For heavy DHW demand, DHW cylinders with capacities of 160, 200 and 300 litres are available that are installed alongside the Vitodens 300-W.

Can be combined with solar thermal systemsFinally, for use in conjunction with solar thermal systems, versions of the Vitocell 100-W are available with capacities of 300 and 400 litres. DHW heating with free solar thermal energy can reduce energy bills by up to 60 percent.

The extremely sparing use of valuable natural gas and low electricity consumption also result in lower CO2 emissions. Consequently, system users are also making an active contribution to protecting the climate.

The stainless steel gauze on the
