Same innovative technology, new sleek design

HydroFLOW® Pearl

Limescale can be a major problem in hard water areas, causing blockages, requiring replacement of equipment, and decreasing heating efficiency and thereby increasing costs. Just 0.8mm of limescale can decrease heating efficiency by as much as 10%*.

Observations have shown that the use of a HydroFLOW® Pearl may over time, lead to a reduction in the existing and problematic hard encrusted limescale from heating surfaces. Less limescale means greater efficiency.

Domestic Limescale Protection

The HydroFLOW® Pearl, an upgrade from the HS38, first developed in the UK in 1992, represents the pinnacle of domestic limescale protection.

With its innovative patented design and unique, electronic signal, the HydroFLOW® Pearl is suitable for installation in houses of up to four bedrooms, and can protect combination boilers as well as vented and unvented cylinders.

The HydroFLOW® Pearl is designed to protect against hard limescale deposits in domestic pipelines and on heating elements and surfaces, to protect appliances such as dishwashers and washing machines, and to make limescale-stained taps, sinks and bathtubs easier to clean.

Protecting the heart of your home

Two cylinders were removed from neighbouring houses in the hard water area of Farringdon, South Oxfordshire. The plumber (Andrew Mugleston) noticed one was much heavier than the other and opened them up to see why.

The heavier cylinder (left) contained lots of hard scale which would have reduced efficiency and loss of hot water volume.

The lighter cylinder (right) had been protected by a HydroFLOW® Pearl, and the cylinder and coil remained clear of limescale, keeping them operating at maximum efficiency.
