    EU labelling: “Solar devices to be classified as heaters”

    The German-based Solar Heating Initiative has developed a new calculation method to label solar thermal systems based on the Ecodesign Directive 2005/32/EC. It put the method, which allows for a fair assessment of solar thermal energy input into a heating system, forward for consideration...

    Three labels in Europe – what are the differences?

    Labels and trademarks should give the end-consumer a clear feedback on the quality and performance of the labelled product. Currently there are three labels available for solar products or solar assisted heating systems in Europe, so there is an increasing need to explain the differences to...

    Optimised control strategy for solar district heating in Italy

    Despite its small size, the solar district heating system in Lodi, close to Milan, is one of few in Italy to feed surplus heat into a local network. In March 2017, Linea Reti e Impianti, the public utility based in this city of 45,000, started buying heat produced by a 192 m² solar thermal...

    Green hotel in Italy’s mountains

    Solar thermal performs well even in high-mountain areas during winter season. The installation shown in the photo is proof that combining solar and other renewable technologies, such as biomass boilers and a solar-assisted heat pump, results in a synergy that can be very productive. The...
