Polski Instalator – Solar collectors: underestimated potential – Polish

Not everyone knows that, according to the requirements of the so- Ecodesign and Energy Labeling and Regulations 811 and 812/2013, solar collectors are included in the labeling only when incorporated into a hybrid kit. Individuals are not subject to such a requirement, which, in the view of many investors, indicates that their advantages are not. Meanwhile, this technology, which is still being developed, has unquestionable advantages today, therefore its formal situation has prompted a common, vigorous action by industry circles in EU countries.

rom 26 September 2016, almost all installed heating and DHW appliances are allowed to be sold in the European Union only with energy labels attached to them. These labels are intended to contain a variety of information that will enable users to be aware of the choice of higher energy efficiency devices. However, solar collectors, as self-contained devices, in accordance with current regulations, are not subject to this obligation. The European Commission has adopted the view that since collectors do not require external power supply, they will not be subject to the obligation to classify energy as other energy-consuming appliances. Exceptions are thermosyphon systems with integrated power supply – the relevant regulation defines these devices as preheating water. According to the procedures for calculating solar water heaters, the highest energy class is defined in this case at level A Given that electric water heaters have a predefined efficiency of 40% and energy class C or D, by connecting them to the solar collector system, they have The self-contained solar collectors for hot water and heating, which, according to DIN CERTICO guidelines, achieve the energy class A +++, are not classified at all.
