This product works as advertised. Need to let it do it’s thing for at least 3 to 4 weeks and you will see a difference. Highly recommended

Excellent performance within minutes of installation.

I was being particular to what water conditioner system I wanted since I did Not want a softener. The Hydroflow offered an alternative I hadn't completely considered. After installation I noticed an immediate change in our water. It has improved the taste of my water by electronically removing the chlorine and breaks up the calcium. I use the carbon filter on my fridge and the water in our coffee and kettle taste better than without. I see less and less calcium floating telling me there is still some residue in my plumbing. I find my soap use has dropped as well, my dishwasher is shiny and with cleanup cleaning has improved, things don't stick in out SS sink like they use to. We feel healthier from drinking it and the ice cubes are becoming clearer, again maybe residual residue. I have recommended this unit to several people and suggest you buy one.


Bluish stains on silverware in dishwasher completely eliminated. Also no hard sediment on humidifier wick. Very happy with unit.

I am a skeptic when it comes to these types of products, but I am happy to say that this product delivers what it promises. We live in a condo with hard water and they definately made a difference to water quality. You would actually think we had a water softner installed.

AWARD WINNING: This revolutionary technology was awarded the Innovative Technology Award from the Water Environment Federation (WEF). Product is also a recipient of the Kitchen Innovations award by the NRA (National Restaurant Association)

The hs38 is the solution for hard limescale deposits in the home. It is designed to protect your, Residential Hot Water Heater as well as appliances such as dishwashers and washing machines, and to make limescale-stained taps, sinks and bathtubs easier to clean.

Limescale build-up in domestic heating systems can cause blockages, necessitating replacement of equipment, decreasing heating efficiency and thereby increasing costs. Just 0.8 mm of limescale can decrease heating efficiency by as much as 10%*.

Unlike other water softeners on the market, the hs38 does not chemically alter the water or remove minerals. Instead, it applies an electric field so that scale forms in suspension in the water, rather than as a hard encrustation on heating elements and pipe surfaces.

The hs38 fits easily around existing pipework on the cold feed to where the water is heated, for example on the inlet to a hot water cylinder or the inlet to a combination boiler.

  • REDUCE COSTS: Reduces energy consumption with an average one year payback period.

  • EASY INSTALLATION: Non-intrusive and easy to install! No plumbing modifications required. Maintenance-free. Works on any pipe, even PEX and PVC - just attach to cold water line into Hot Water tank or Boiler. Fits pipes up to 25mm (1”) outer diameter.
