Special Features

• space-saving ‘100% solution’
• pre-insulatedtwin pipes
• maximum energy savings with extreme space-efficiency
• requires less than half the space needed by separatly laid solar pipes

While the German Energy Saving Ordinance (Energieeinsparverordnung - EnEV) does not explicitly state requirements for the insulation of solar pipes and leaves room forinterpretation, the Building Energy Act (Gebäudeenergiegesetz- GEG) will close this gap in the law. According to the draft billfor the GEG, the average value of heat distribution lines mustnot exceed 0.25 W/( m · K). This means that solar pipes must be insulated with a wall thickness of 100% according to EnEV. As a result, space can soon become tight in installation shafts,not only when they are used for various pipes.
