About the Janker Family
The Janker family resides in Berlin, Germany, in a home with an interesting history—an old building with an extension built in 1991. Like many German homeowners, they take water quality seriously and were proactive about finding the right solution for their high-hardness water.
Their journey to find the perfect water treatment solution was methodical: they tested not one, not two, but three different devices—the Vulcan 5000 alongside two magnetic systems. This head-to-head comparison provides rare and valuable insight into how different technologies perform under real-world conditions.

A Methodical Comparison: Vulcan vs. Magnetic Devices
"We installed the VULCAN 5000 device for a trial period back to last year. As the results of the device during the trial period were positive and conformed with our decalcification requirements, the only thing preventing us from making the purchase immediately was that we were waiting to test two further devices."
The Competitors
- Magnetic Device #1: "The effect of one device was incomparable" (meaning no comparison—Vulcan was clearly better)
- Magnetic Device #2: "The other device was difficult to assemble due to incorrect dimensions"
The Winner
- Vulcan 5000: Delivered positive results that met their decalcification requirements
- Installation: No problem despite challenging conditions
Installation: Tight Space, No Problem
The Challenge
"Since our family house is an old building with an extension built in 1991, the water pipelines are so laid out that the distance from the wall to the centre of the 1 inch supply line is only 25mm."
The Solution
"Despite this narrow width the installation of the VULCAN 5000 device was not a problem."
From Trial to Purchase
"After we sent back your device and the other two shortly after, we put off the issue of water softening and decalcification. However, after visiting the 'Heim & Handwerk' trade fair in Munich this year, we decided to purchase your device, due to our high water hardness."
The Janker family's journey shows that sometimes the best decisions are made after careful consideration—and reinforced by seeing the technology in person at a respected trade fair like Heim & Handwerk in Munich.
Visible Results After Installation
"Since the installation we have noticed the immediate effects of softer water as well as a decrease in the amount of scale. The reduction of scale is particularly visible in the transparent water container of our espresso machine as well as in the aerators."

Final Verdict
"We are confident that we have purchased the correct device for our house with a good price/performance ratio."

The Winner in a Fair Fight
The Janker family gave Vulcan no special treatment. They tested it alongside two competing magnetic devices, in their own home, under the same conditions. Vulcan emerged as the clear winner—delivering the results they needed, installing easily where others couldn't, and earning their purchase after a trip to a trade fair. This is real-world proof that impulse technology outperforms magnetic alternatives.
