Design & Technology

High pressure hot water boilers from Viessmann are the result of decades of research, development and testing - not just in our factory but also through numerous installations around the world. The result is our advanced heating systems that both meet and exceed key requirements such as low emissions levels and efficiency. As a result, they offer significant savings potential from the outset, and are designed to be futureproof, ensuring that they continue to return the investment even as energy supplies evolve and regulations become stricter.

Our innovative solutions have been deployed in a variety of applications that includes not just large scale residential developments and highly productive industrial complexes, but also projects in the commercial sector, historical listed buildings and many other unique settings.

As a company, we have a strong emphasis on renewable energy sources and design and develop all of our technology with these in mind.

Saving energy and protecting the climate

Viessmann is aware of its responsibility towards the sustained protection of the environment. Our company philosophy and products have been constructed with this duty in mind.

"Nothing is so good that it cannot be improved". This motto is also reflected in our company principles. Viessmann can rightfully claim to be the leader in quality and technology, and as such, aims to continually set new standards. Of course, this applies in particular to the company's product range, which is consistently geared towards significantly lowering the consumption of fossil fuels and gradually replacing them with renewable sources of energy.

At around 40 percent, the heating market actually accounts for the largest proportion of energy consumption. The rest is shared by road haulage, personal transport and power generation, each accounting for 20 percent. Similar values also apply to other industrial countries. Ever-rising energy costs mean that the priority is to reduce the consumption of fossil fuels as quickly as possible.

Industrial boilers for every application

Due to their design and equipment level, Vitomax industrial/commercial boilers deliver the best possible conditions for meeting individual customer requirements in a broad range of applications. 

The detailed design of the Vitomax boilers and the company's vast experience in building industrial boilers ensure superior quality, high operational reliability and a long service life. The comprehensive product range from Viessmann includes hot water boilers up to 20 MW.

Condensing technology offers the greatest energy efficiency

Viessmann gas condensing boilers convert up to 98 percent of the natural gas used into heat, reducing the CO2 footprint and also saving money through increased efficiency.  Conventional fuels can also be combined with biofuels such as bio natural gas, making condensing technology versatile and futureproof.

By choosing to invest in advanced condensing technology, you could begin making considerable savings immediately, as well as making an effective contribution towards the sustained protection of our climate by preventing unnecessary CO2 emissions.
