When 47%* of all energy use in the home is taken for heating and cooling and 14% for water heaters, it is important to consider all the household energy savings one can make.

Protecting water systems since 1992

Since 1992 HYDROPATH has been addressing some of the most persistent problems that occur in water systems such as Limescale and Biofouling. HydroFLOW® is a patented, no-chemical water treatment technology and in 2021 HydroFLOW® was recognised by Solar Impulse Foundation as a clean technology, both profitable (it saves the customer money) as well as sustainable (saving on water, energy and chemicals.)

The Solar impulse Foundation, a non-profit organisation was founded by Bertrand Piccard who successfully piloted the first solar-powered round-the-world flight.

HydroFLOW® water treatment

HYDROPATH has designed a range of HydroFLOW® water treatment devices for the home and industry such as agriculture and manufacturing and for water systems in commercial buildings.

Limescale in home water systems can be a major problem in hard water areas. Just 0.8mm of limescale can decrease heating efficiency by as much as 10%. It is worth considering the energy savings which can be made by addressing limescale in your home.

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 HS38, and the cylinder and coil remained clear of limescale, keeping them operating at maximum efficiency.

7 reasons to choose HydroFLOW®

In 2021, John Lawton, Technical Product Manager of Intergas Heating UK wrote: “Limescale build-up can defeat the best heating designs and installations if preventative action isn’t taken”. In his opinion: “…the HydroFLOW HS38, an electronic water conditioner, should be a vital constituent of every central heating system, to ensure the long term, efficient operation of domestic central heating systems.”

Here are the seven reasons that Intergas choose HydroFLOW®


Easy to install

It’s simple to install under the boiler (on the cold inlet pipework)


Low operation cost

It’s powered directly from the boiler PCB ( no external power source required) with a three- metre cable supplied (only costs approximately £1.50/year to operate)


Easy to retrofit

It clips onto the pipework via a patented clamp system (no need to cut the pipework or drain the water)


Sustainable – no chemicals

It’s environmentally friendly as it does not use any chemicals (competitors use electrolytic types that have zinc sacrificial anodes which release small amounts into the water)



It has a patented electronic water conditioner technology where the signal propagates around the entire hot and cold water pipework, which is unique to Intergas as we don’t use plate-to-plate heat exchangers so the waterway is always open allowing the electronic signal to flow with an uninterrupted signal.


New/existing limescale

The signal causes any limescale present to bond together (cluster) and, when subjected to heat, it will crystalise and travel out of the pipework with the water flow, preventing any build-up or damage occurring. The signal will also breakdown any existing limescale that has adhered to the internal pipework eventually clearing over time, subject to flow rate, temperature and hardness.


Signal travels in all directions

The signal can flow up and downstream of the HydroFLOW HS38, providing there is a clear path within the waterways, however we recommend it is fitted closest to the heat generating source for the best results.
