More effective and 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. 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...

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 that 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 boilers with...

MatriX-Plus burner A milestone in heating technology – the highly environmentally responsible MatriX gas burner for the Vitodens 300 series

Over the 100 plus years that Viessmann has been in business, the company has regularly set new milestones in the development of highly advanced heating technology. 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. MatriX-Plus burner milestone With the MatriX-Plus burner in the Vitodens 300 series, high energy...
