Hydroflow S38

We installed this unit, and prior to installation we descaled our electric kettle. Over a month later, haven't needed to descale again. Appears to be doing exactly what it promises. Satisfied customer.

'Smoother' water

HydroFLOW Pearl Plus was very easy to install.
Before Pearl Plus, the TDS reading from my kitchen cold water tap was 179 ppm. The next day the reading was 173 ppm. Two days after that it was 166 ppm. 5 weeks later the reading is 166 ppm.
I believe that the water tastes 'smoother'. My laundry also seems to be cleaner.
I am pleased with the Pearl Plus.
The staff at the Burlington office were very professional and helpful !

Happy to never buy salt again

Purchased two units and I was a little sceptical, but have been surprised on how good they work. No stains on sink bright work and rings around the toilet bowl.
One unexpected benefit is better water pressure and flow with the old salt softener removed.
Very easy to install and so far no problems.

The HydroFLOW® Pearl PLUS is the solution for hard limescale deposits in the home. It is designed to protect your residential hot water heating system as well as appliances such as dishwashers and washing machines. In the majority of cases to eliminate limescale-stains from taps, sinks and bathtubs or make them much 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/conditioners on the market, the HydroFLOW® Pearl PLUS 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 HydroFLOW® Pearl PLUS 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.

  • ECO-FRIENDLY: Our water softener products do not introduce chemicals into your drinking water and the environment.

Installation of this device does not replace periodic equipment preventative maintenance procedures, such as purging of your water heater.
