gas condensing boilers up to 105 kW

Introduction
Established in 1917, Viessmann draws on more than 90 years of experience in the
development and manufacture of heating systems and due to its high commitment to
quality, it is Europe's single largest brand in heating technology. Viessmann is a third
generation family business and as such is able to hold true to its principles of innovation,
efficiency and sustainability; this is a significant reason behind Viessmann's
continuing success.
Viessmann's domestic product range has been built around a long established reputation for
high quality commercial heating systems. Viessmann has utilised its extensive knowledge
and expertise to develop domestic heating products that define the quality benchmark
for other brands. Viessmann manufactures all of its own products and controls to ensure
that the drive for quality remains throughout the entire range and that there are additional
benefits from combining its heating technologies. Viessmann produces and sells products in
the following sectors: high efficiency boilers, both domestic and commercial; solar thermal
flat plate and tube collectors and PV panels; air source and ground source heat pumps;
biomass boilers; and CHP units for commercial and domestic use, using a number of fuels
including biogas.
However the principles of innovation, efficiency and sustainability don't only apply to
products, but extend to all areas of the business. Viessmann's head office and production
facility in Allendorf, Germany, was restructured from 2007 to 2009 at a cost of 220 million
Euros and energy use was aligned with European climate change goals, of a 20% reduction
in energy usage and CO2 emissions and a transfer of 20% of energy production into
renewables, by 2020. In 2009, under the umbrella of the 'Efficiency Plus' project, Viessmann
achieved its goal of saving 40% of oil, gas and electricity through the use of renewable
energy while at the same time reducing CO2emissions by a third. Almost all measures to
improve efficiency and renewable substitution were achieved with commercially available
products made by members of the Viessmann Group; whether these were Solar panels,
CHP units, Oil, Gas or Biomass boilers.
For this project, Viessmann received the German Sustainability Award 2009 in the category
"Most Sustainable Production" as well as the German Energy Agency’s Efficiency Award
in 2010. In addition, Viessmann was honoured with the 2011 German Sustainability Award
in the category "Most Sustainable Brand". These awards recognised the company's
achievement of combining economic success with social responsibility and environmental
conservation. Hence Viessmann products contribute to reducing the carbon footprint of UK
homes even before they are installed.
