Introduction Did you know? Good reasons for modernising your heating system and using efficient gas condensing technology. In Germany alone, there are still around two million heating systems in use which are over 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 escapes through the chimney as unused heat. Furthermore, these old systems have an impact on the climate through unnecessary CO2 emissions which contribute to global warming. By promptly replacing these systems with highly efficient...

8/9 More effective, more economical with lower emissions – advanced gas condensing technology from Viessmann 2 % + 8 % 90 % 98 % How condensing technology works: Viessmann boilers, with condensing technology, achieve an efficiency of up to 98 percent (relative to Hs [gross cv]). Through the condensation of the water vapour in the flue gas, additional heat is extracted from this vapour and fed back into the heating system. This increases the efficiency, lowers your heating bills and reduces the environmental impact.

Things you need to know about modernisation An investment that pays dividends Optimum heating output for any living space. If you are planning a new build or modernisation project, you should factor in the right heating system for your requirements in plenty of time. You can save a lot of money by calculating your actual demand before selecting a boiler. The small boilers series includes gas condensing boilers with an output ranging from 1.9 to 105 kW. From a small flat to an entire apartment building, the Viessmann product range always offers the right solution. Heating economically With...

12/13 Viessmann sets standards Over the 90 plus years that Viessmann has been in business, the company has regularly set milestones in the development of the most advanced heating technology. Viessmann has been a pacemaker in the heating technology industry for decades. Through continual innovation, the efficiency achieved when converting energy into heat has been increased to the limit of that which is currently technically possible. At the same time, we have been able to drastically reduce the levels of energy consumption and CO2 emissions of our boilers. The MatriX burner – a true...

A milestone in innovative heating technology: the use of high-alloyed stainless steel. Applied here in our Inox-Radial heat exchanger.

14/15 Gas condensing technology You can either sit there thinking about how futureproof your heating system should be – or you simply switch to the future right now. With Viessmann gas condensing technology, the heating technology of tomorrow is already available today. It is one of the most economical and cleanest ways to generate heat. Through the condensation of the hot gases, latent heat is recovered which is normally wasted by conventional boilers.
