Condensing technology protects the climate and the environment ll 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 resources Viessmann 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. s 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 energy Every new heating system, nowadays, should also be able to work with solar collectors to benefit from free solar energy. ll Viessmann boilers are set up for this right now.

6 Introduction More effective, more economical with lower emissions advanced gas condensing technology from Viessmann 2 % + 8 % 90 % 98 % 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. Viessmann works continually to develop new, environmentally responsible solutions, resulting in ecofriendly, cost effective and efficient heating systems.

7 6/7 Replacing old boilers saves up to 35 percent on energy bills Good reasons for modernising heating systems using efficient gas condensing technology. 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 CO 2 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 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 CO 2 emissions. total energy needs, with annual CO 2 emissions simultaneously being reduced by 54 million tonnes. Central heating backup with solar technology Free 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 technology With 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.
