HS38 Works Great

After using the HS38 for about a month, I am quite happy with the results. My tea kettle does not need to be cleaned with vinegar nearly as often, and a quick brushing mostly cleans up the small amount of scale that does form.

Vous en donne pour votre argent et plus

Nous sommes passé du sel à Hydro-Flow et franchement, c'est économique considérant les hausses du prix du sel, extrêmement moins encombrant que l'attirail du sel et enfin fini la pollution par les lavages à rebours de la machine à sel.

Vraiment content d'avoir opté pour Hydro Flow

City | Town Treated Water - for Small Homes (< 3000 sq ft incl basement area) Plus Condos, Cottages, and RVs.

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.

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

If the Product or any of its parts fails during the first three years of operation, HydroFLOW or its representative will repair or replace the Product, free of charge. For this warranty to apply, you will need to provide proof that the Product has been installed properly and before-and-after proof that such Product is not operating as warranted. What Is Not Covered: This warranty does not cover damage to the Product caused by improper installation, a surge or disruption in power (however caused), a water leak resulting from limescale removal, misuse, abuse, or force majeure (i.e., a flood or earthquake, etc.). Please be aware that water leaks from plumbing systems may result as a consequence of limescale removal. You are therefore advised and have a duty to periodically inspect your plumbing systems to ensure that compression joints remain water-tight.

A HydroFLOW representative will then review your claim and contact you within 10 business days to coordinate the repair or replacement of the Product or to request additional information. Limitations: Warranty claims are strictly limited to the value of the original purchase price or the repair or replacement cost. HydroFLOW shall not be responsible for water leaks or damage caused by the removal of limescale. This warranty is not valid unless the Product is properly used with an appropriate surge protection device of adequate quality to protect the Product and its electronic components. HydroFLOW will not be responsible for any consequential, incidental, indirect, special, punitive or other loss or damage that may result from a product defect. HydroFLOW reserves the right to determine the validity of any claim and remedy in its sole discretion.
