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.

Innovative technology such as the new gas adsorption heating appliance reduces gas consumption by a further 25 percent compared to conventional condensing technology, saving fuel, reducing emissions still further and making heating with gas even more efficient.

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.

Right from the start, Viessmann has been one of the leading suppliers of heating equipment. Ongoing innovation has raised the efficiency in converting energy into heat to the limits of that which is currently technically possible. At the same time, we have been able to drastically reduce energy consumption and CO2 emissions of our boilers.

The MatriX burner – a true milestone in heating technologyThe MatriX gas burner is your guarantee of high energy efficiency and heating convenience. Combined with the stainless steel Inox-Radial heat exchanger, this technology reduces heating bills and minimises harmful emissions, with no need for compromises.

The Lambda Pro Control combustion controller makes Viessmann gas condensing appliances futureproof. They adapt automatically to various types of gas and can even operate with partial biogas mixtures or LPG.

A milestone in heating technology: The extremely

environmentally responsible MatriX gas burner

Environmentally responsible and energy efficient technology from Viessmann sets the standard

Over nearly 100 years that Viessmann has been in business, the company has regularly set new milestones in the development of the most advanced heating technology.

Stainless steel heat exchangerAll Viessmann gas condensing boilers feature a stainless steel heat exchanger. This technology brings with it an extremely high efficiency rate of 98 percent and exceptionally reliable and efficient operation during its long service life. Viessmann guarantees Inox-Radial heat exchangers up to 150 kW for ten years against leaks resulting from corrosion.

Award-winning designFor Viessmann, top technology and an attractive design go hand in hand. In recent years, the company has received more than 40 significant design awards from all over the world for its products. Viessmann boilers have won the renowned red dot design award twenty times.

Certified hydronic balancing for subsidy programmesHydronic balancing is a must for the efficient operation of any heating system.

Viessmann's solution for this is the Vitoflow 300 – an automated process for all gas condensing boilers up to 150 kW. After the completion of the TÜV-certified process, default settings for each radiator valve and the optimum pump speed and heating curve are recorded on a printout. This provides the user with the necessary verification to be submitted with any application for KfW subsidies [Germany]. The optimal setup of your heating system also enables energy efficiency to be increased by up to 15 percent.

VITOSORP 200-F

The Vitosorp 200-F gas adsorption heating appliance combines the benefits of heating with gas and those of utilising natural heat. The combination of gas condensing boiler and adsorption module reduces gas consumption by more than 25 percent, compared with conventional condensing technology. This saves fuel, protects the environment and makes heating with gas more efficient.

Combining a gas condensing boiler and zeolite gas adsorption module in a single appliance reduces gas consumption by around 25 percent compared to conventional condensing technology.

Proven condensing technology combined with geothermal or solar energyThe Vitosorp 200-F consists of a zeolite adsorption module and a gas condensing boiler. The adsorption module utilises free geothermal or solar energy to cover the base load of a building's heating demand. Geothermal collectors, geothermal probes or solar thermal systems can be chosen to tap into one of these sources of thermal energy from the environment.

The gas condensing boiler fuels the adsorption process and covers the peak loads that inevitably occur on particularly cold days, in order to provide extra heating for domestic hot water.

Flexible utilisation of thermal energy from the environment The special design of the Vitosorp 200-F allows flexible and affordable utilisation of geothermal or solar thermal energy. Solar collectors, geothermal collectors or geothermal cages are available for new build. In existing buildings, the solar collectors already installed can be used as a primary source. A vertical, 60 metre deep geothermal probe would be a space saving geothermal solution.

Ideal for modern livingThe Vitosorp 200-F is designed to meet the heat demand of detached houses. It is particularly efficient in new build. The use of environmental energy ensures a secure supply for the future. This unit meets the stricter EnEV 2016 requirements [Germany] for new build. However, the Vitosorp 200-F is also an efficient solution for modernisation projects, as flow temperatures of up to 75 °C are feasible (recommendation < 55 °C).

Easy handling and installation save time and money. With its compact dimensions, a width of only 600 mm for example, the gas adsorption heating appliance fits snugly into the space of a standard kitchen unit (minimum ceiling height 2.20 metres). Low operating noise and the harmless combination of materials – zeolite and water – allow operation inside the living space.

Proven performance and low maintenance The zeolite heat pump module is hermetically sealed and therefore completely maintenance free throughout the service life of the appliance. The gas condensing boiler in the Vitosorp 200-F has a proven track record of high reliability and low maintenance going back many years.

SubsidiesAdditional incentives for investing in this innovative heating technology are available from the German Federal Office of Economics and Export Control (BAFA). Further funding is available in addition to basic funding (see www.bafa.de).

This ensures consistently high energy efficiency and offers security for the future in liberalised gas markets and where biogas is added to natural gas.

Available as a system or combi boilerThe Vitodens 200-W is optionally available as a system boiler with separate DHW heating, or as a combi boiler delivering up to 35 kW with an integral instantaneous water heater. This ensures that DHW and central heating are available without taking up too much space.

Cascading up to 594 kWThe Vitodens 200-W wall mounted gas condensing boiler can also be used in a multi boiler system with up to four appliances. Total output can then be as high as 594 kW.

The integral stainless steel loading cylinder on the Vitodens 222-W, with its 46 litre capacity, is particularly worth noting. This volume is comparable to a 150 litre DHW cylinder where hot water availability is concerned. The water heated to the required temperature in the heat exchanger (instantaneous water heater) continually charges the loading cylinder and is, therefore, immediately available for further drawings.

All system components such as the loading cylinder, expansion vessel, pumps and safety valves are factory fitted, reducing the time spend on installation on site.

For state of the art heating with condensing and solar technology in detached houses, the Vitodens 242-F is an extremely energy efficient, environmentally responsible and advanced heating system. With a footprint of just 0.4 m2, this storage combi boiler needs only a small amount of space, so can fit into any recess. High DHW convenience is guaranteed by a dual mode loading cylinder with 170 litre capacity and solar indirect coil.

Futureproof through solar integrationThe Vitodens 242-F is fully prepared at the factory for combination with Vitosol solar collectors (or an existing system), either now or in the future. The control module for regulating the solar thermal system is already integrated; the solar yield is displayed graphically by the device. All functions are matched to one another and have been factory tested.

Over 50 percent of the energy needed for DHW heating can be saved with this appliance, using free solar thermal energy.
