he world’s largest trade fair for T energy-efficient heating and air- conditioning technologies, renewable energies and innovative bathroom design, ISH Energy 2013, was held in Frankfurt am Main from 12 to 16 March. More than 2,400 exhibitors showcased their new products over an area of almost 260,000 square meters. The event attracted some 190,000 visitors, 06 with more than a third coming from abroad.

The following pages contain a review of five exciting days. Both text and pictures illustrate the trade fair highlights for Viessmann. ISH 2013 The Viessmann stand at the leading international trade fair The “climate of innovation” brand promise was also the company’s main motto at ISH Energy 2013

Here, vis- itors could experience the future-orient- ed concepts developed by Viessmann for producing, distributing and using energy, which are pushing forward the conversion of the energy supply to- wards greater efficiency and renewable energies.

The energy efficiency check clearly showed energy system operators how to significantly cut energy consumption in single-family homes and large residential buildings. The result was presented on a large-scale displayboard. One of the numerous highly efficient solutions showcased at the large stand: Dr. Frank Voßloh, Managing Director Viessmann Deutschland GmbH (center), and Product Sales Manager Mike Redder (right), are explaining the micro CHP compact device Vitotwin 350-F to Dr. Uwe Kolks, member of the management of E.ON Deutschland GmbH.

In addition, smart grids – intelligent net- works that make efficiency potential available while distributing energy and increase operational reliability – need to be developed to enable households to benefit from this new efficiency poten- tial.

Vitodens 200-W High output in tiny spaces

The power output range for the gas condensing boiler Vitodens 200-W has been extended to include capacities of 125 and 150 kW. These new units only require 60 percent of the space used by a floor-standing condensing boiler producing a similar output and weigh only half as much.

Another advantage of the new wall- mounted unit is its reliable high operating pressure of 6 bar. Such pressure can be used to supply heat units can be arranged in a cascade.

Micro CHP system Vitotwin in the town hall of Brugg (Switzerland) Following a complete modernization of the building, heat and electricity are now being produced simultaneously.

he small Swiss town of Brugg is well T known far beyond the boundaries of the canton Aargau because of its well- preserved old town, still largely original with buildings up to 800 years old. The town hall is around 300 years old, and was first used for grain storage and then in the course of the centuries for various other purposes. Last year the building was thoroughly modernized. Since then, a micro CHP Vitotwin 300-W in the 35 heating center has been producing heat and electricity simultaneously.
