For generations, Viessmann has strived to provide innovative and sustainable heating solutions. Research and development form the foundation for our technological progress, and ensure that we have top quality products and competitive heating solutions. Viessmann plays a major role in how families will use heating systems in the future, and we want to ensure that we are creating products which can be used in a sustainable environment for generations to come.
Historic innovations – a few of our milestones
Viessmann's list of technological milestones is long. In our 100 year history we have over 1,500 registered patent families and registered utility models. Viessmann has designed groundbreaking innovations since day one, and we fully intend to continue developing outstanding products and system solutions that have a decisive influence on technological progress.
The following examples show some of the key milestones in our history of innovation.
ThermProtect technology protects solar collectors from overheating
In the past, solar collectors had a problem with overheating if the heat they collected was not used up, causing steam to build up inside and damage the collectors. In 2017, Viessmann developed and patented new ThermProtect technology to overcome this problem. ThermProtect is an intelligent absorber layer, with an internal crystalline structure that changes when a certain temperature limit is reached, in order to lower the max temperature inside the collector.
Innovative technology made by Viessmann
Innovation in fuel cell technology with Vitovalor
In 2014, Viessmann brought the first mass-produced fuel cell heating device onto the market – a world first. Vitovalor works in a highly efficient, reliable and environmentally friendly way. The device converts natural gas into electricity and heat. This operates through a chemical process, not through the combustion of fossil fuels as in conventional systems. In this so-called "cold combustion", hydrogen reacts with oxygen, which creates electricity and heat. This technology helps protect people from rising electricity prices, and at the same time safeguards the environment.
Vitola biferral composite heating surface
In 1976, Viessmann paved the way for the era of low-temperature hot water heating in boilers, by creating the Vitola biferral composite heating surface. This double-wall heating surface consisted of a combination of steel and cast iron, and enabled the controlled transfer of heat while allowing the boiler to operate without a lower temperature limit. The boiler no longer had to be operated at a constantly high temperature of 70°C, and could be switched off and started up again "cold".
Viessmann innovation and leading-edge technology
At Viessmann we are always at the forefront of cutting-edge technology and design innovation. Using innovative products and solutions to protect the environment and preserve the planet as a place worth living in has always been our prime motive.
Inox-Radial heat exchanger for efficient heat transfer
At the end of the 1980s, Viessmann set a milestone in heating technology history with its design of the Inox-Radial heat exchanger. The design is an in-house-developed, spirally wound rectangular stainless steel tube, instead of a tube with a round cross-section. The Inox-Radial heat exchanger ensures excellent heat transfer due to the innovative design with a constant gap of 0.8 millimeters and the laminar flow. This heat exchanger is used in all of our Vitodens gas condensing boilers.
