How does ActivFlo combat limescale?

Backed by over 40 years of scientific research and testing, ActivFlo conditions hard water as it enters your home using a special alloy and some clever science. This prevents limescale build-up and prolongs the lifespan of your water system and appliances.

  1. The unique patented spiral alloy coil creates turbulence which agitates the water flow
  2. ActivFlo features a 316 grade Stainless Steel body, precision engineered in the UK for a longer 20 year lifespan and 15 year guarantee
  3. Internal slip socket for easy installation. A competent DIYer can even fit ActivFlo using basic tools.
  4. Thanks to a tiny electrical curent created by the turbulence, minerals passing through the ActivFlo are prevented from combining together to form crystals.
  5. Calcium Carbonate is converted into insoluble aragonite crystals, which don’t bond easily on surfaces, outlets and appliances - meaning less limescale buildup.
  6. ActivFlo does not eliminate minerals, such as calcium, from your water supply, so you can continue to enjoy the benefits of mineral-rich water.

Benefits include

ActivFlo. A simple way to put a stop to limescale damage cased by hard water in your home.

Home Efficiency Improvements

Homes in hard water areas are more at risk of limescale build-up, which means water systems and appliances don’t work as well as they should. It can lead to pipework corrosion and cause failure of parts in washing machines, dishwashers and boilers — all of which are expensive to replace.

Water that has been conditioned by an ActivFlo unit prolongs the life of your water system and appliances, helping them run at their best for longer. This improves household energy efficiencies, which – in turn – reduces energy bills.

It’s also good for the planet

Water systems and appliances that work more efficiently will use less energy, and consequently have a lower carbon footprint.

With an ActivFlo unit requiring no energy or maintenance, it has no environmental impact, so you can rest easy knowing you’ve done your part for the planet – at the same time as reducing your energy bills.
