System technologySolar thermal andphotovoltaicsVacuum tube collectors can beinstalled anywhere, and in newbuild also make for an attractivearchitectural feature.Solar thermal – free solar energyAll medium and industrial/commercial boilers can be combined with suitable solartechnology. In such cases, the free solar energy provides the DHW heating.A new heating system and a solar thermalsystem simply go hand in hand. There are goodreasons for this. In the summer, the majorityof the energy demand for DHW heating can becovered by solar collectors. Subject to systemsizing, the system can also provide centralheating backup.Calculated over the year, 60 % of energy canbe saved on DHW heating alone. After all, solarenergy is free, and daylight is converted intoheat by the collector even when the sun is notshining directly onto the roof.Particularly on commercial buildings, the wideexpanse of flat roofs offers an ideal base forthe installation of collector arrays.The principle is quite simpleOf course, the utilisation of solar energyrequires innovative technology and lots ofexperience: Solar thermal systems “harvest”solar energy in the flat-plate or tube collectors.In these, a heat transfer medium is heated bythe insolation and routed into a DHW cylinder.There, the heat is transferred to the potablewater to be heated via internal indirect coils,

60/61alternatively to the heating circuit via heatexchangers. Thereafter, the cooled liquid isreturned to the collector, and the cycle beginsagain. If the insolation is insufficient, e.g. inwinter, the boiler provides reheating.The Vitosol range offers solar collectors forevery aspiration and every budget. Installationon the roof or wall opens up a variety of designoptions.Flat-plate and tube collectorsThe Vitosol 200-F flat-plate collector standsout because of its high quality, lastingoperational reliability and high efficiency. Withits extremely translucent anti-reflex glass andhighly selectively coated copper absorber,the high performance Vitosol 300-F flat-platecollector utilises the intensive solar radiationparticularly efficiently.The Vitosol 200-F flat-plate collector features frost and hailproofsafety glass as well as corrosion-proof componentsmade from steel and aluminium. The frames are available onrequest in any RAL colour.Outstanding quality you can rely on.More information at www.test.deThe Vitosol 200-T vacuum tube collectoris characterised by its particularly effectivethermal insulation and high efficiency resultingfrom its Sol-titanium coating. It can be installedanywhere.The Vitosol 300-T meets the highest demands.This top quality, high-performance collector isdesigned around the heat pipe principle.The Vitosol 200-T and Vitosol 300-T vacuum tube collectors aremarked out by their superior reliability and long service life.Generate your own power with VitovoltThe Vitovolt 200 and Vitovolt 100 photovoltaicmodules generate electrical energy right in thesolar cell, which is fed straight into the publicgrid via an inverter.Benefit from public subsidiesYour Viessmann trade partner is well-informedabout current subsidy programmes and willgive you the most important contact details toobtain information and application forms.Or simply take a look on the internet:www.viessmann.de/foerderprogrammeVitovolt photovoltaic modules from Viessmann also provide ahigh yield of power generation in partially shaded areas.
