VAILLANT AUROFLOW VMS 70

From the jury's assessment

The “auroFLOW VMS 70” from Vaillant is a modern and efficient solar station with a power-saving high efficiency solar pump, sensors and a new aeration system with “expander” technology. The calculation of the solar yield is done by integrated sensor technology. The round elements for fast reading of core information such as temperatures / pressure and the viewing window allow a fast check on the status of the solar system and the solar fluid. A fully enclosing EPP-casing and a casing closing system in compact built guarantee highest security.
