Umberto Saxer, Aadorf, CH

Reduction of heating costs of up to 30% thanks to GRANDER®

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.

What surprised Umberto Saxer the most was that the blackish and smelly heating water turned clear and odor-free in only a very short amount of time.

And it did so without filtration – the information transfer simply did the trick. ‘To me, this was the most compelling piece of evidence that GRANDER® works!’

Thanks to the optimization of the heat transfer resulting in an overall performance improvement, installing GRANDER® devices starts paying off right away. The vitality the heating water regains creates a pleasant atmosphere in homes and reduces heating costs.
