Already in 2001, GRANDER® Inline Units were installed to revitalize the drinking water in all five buildings of the Wigger residential complex in the German town of Garmisch-Partenkirchen. As the inhabitants’ feedback was so positive, a further unit was installed to also revitalize the complex’s heating system in 2007.
The Fistills first heard about GRANDER® water revitalization from a friend, who highly recommended it. In 2017, the South Tyrolean family decided to get GRANDER® for their home in La Villa/Alta Badia in the Badia Valley.
The parish kindergarten in Oberpullendorf, having relied on GRANDER® water revitalization for many years now, reports: thanks to GRANDER®, the heating water has been crystal clear and has met drinking water quality requirements since 2004!
Dear Ms Fleck, dear Mr Jörger,
For some years now, we have been installing GRANDER® Inline Units in property we manage (all condominium ownership associations). The first installation concerned a floor-heating system in 2009.
GRANDER® made contributions to the following two projects: the ‘Murgtal wood chip heating plant’ project was kicked off in 2011, but after only a few months of operation, contaminations in the plate heat exchanger started causing problems. Chemical, physical, and microbial analyses showed that the contaminations were caused by microbial factors.
The installation of a GRANDER® Circulation Unit has paid off for Umberto Saxer in Aadorf: heating costs have been reduced by up to 30%. As no more silt or rust forms in the heating pipes, the water stays clean and odorless.
As a certified plumber, I didn't only want to know about installations and piping, I was also very interested in what was flowing through them. The chemistry of water has always intrigued me.
