Of course, this applies in particular to the company's product range, which is consistently geared towards significantly lowering the...

Introduction Did you know? Good reasons for modernising your heating system and using efficient oil 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 consumed 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. Central heating backup with solar energy The free energy...

8/9 More effective, more economical and lower emissions – advanced oil 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 the boiler. The range of small boilers includes oil condensing boilers in output stages from 12.9 to 107.3 kW, and ultra-low temperature oil boilers from 18 to 63 kW. From a small flat to an entire apartment building, the Viessmann range always has...

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 advanced heating technology. Viessmann has been the 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 biferral composite heating surface...

14/15 Oil condensing technology VITOLADENS VITORONDENS 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 oil condensing technology, the heating technology of tomorrow is already available today. With its efficiency of 98 percent, oil condensing technology will remain one of the most economical and clean options for generating heat. Through the condensation of the hot gases, latent heat is recovered which is normally lost by conventional boilers. With the Vitoladens or Vitorondens, you're doing...

16/17 VITOLADENS 300-C Our top model offers the best price/performance ratio in its class. You'll love its compact dimensions and outstanding design. Your investment in a Vitoladens 300-C will pay off in only a few years through an annual reduction in the consumption of costly fuel oil, as our condensing boiler uses far less than older boilers on account of its high efficiency. An advanced heating system should include innovative solar thermal technology to utilise free energy from the sun. Viessmann offers you a system for this which is optimally matched to the Vitoladens 300-C. Our...

Oil condensing technology Vitoladens 300-C 12.9 to 28.9 kW Flexible application The Vitoladens 300-C is a highly efficient oil condensing boiler with flexible options for its application. Particularly compact, it is suitable both for use in new build, and as a replacement for old boilers. Highly effective heat exchanger The corrosion-resistant stainless steel Inox‑Radial heat exchanger lies at the core of the condensing boiler. In direct connection with the biferral composite heating surface, the energy used is converted to heat efficiently and with practically no loss. The extremely...
