  • 1 x white housing bracket
  • 1 x Watts OneFlow cartridge
  • 1 x housing spanner
  • Fitting instructions for your plumber

CARTRIDGE DETAILS:

  • FDA grade components and materials
  • Recommended flow rate - up to 18 litres per minute
  • Maximum operating pressure: 125 PSIG
  • Operating temperature: 10°C - 52°C / 50°F - 125°F
  • Tested and certified under NSF / ANSI standard 42 for materials only.
  • Watts canister containing 750ml of A8210 OneFlow anti-scale media / 4.5 x 10"
  • Chemical free scale prevention and protection - converts hardness minerals to harmless, inactive microscopic crystals.
  • Virtually maintenance free - just replace your OneFlow cartridge every 1-2 years.
  • No control valve, no electricity and no waste water.
  • OneFlow is not a water softener. It does not add chemicals into your water or remove the beneficial minerals. 
  • Replacement OneFlow cartridges are available here and we'll email you every 6 months to remind you to check your filter performance. 

Note that OneFlow starts working right away, but there will be residual limescale in your water pipes that can take up to three months to clear before you start noticing the difference. In addition, the efficiency of OneFlow is greater if the water is filtered for chlorine first.

How to cut energy bills

Scale damage to water heater elementScale built up in your water heater or boiler can seriously harm its efficiency.

Apart from that the damage done by limescale means the elements or entire unit will need to be replaced.

Yes, that's right! The working life of anything that heats hard water is much shorter than it should be.

In fact, you may only get half the expected time before you have to replace it.

If you live in a hard water area you've probably already had to buy a new kettle every year or two.

It's the same with gas boilers and electric water heaters.

Even if you don't have a multipoint boiler the element in your immersion heater will also get fouled with limescale.

With boilers costing thousands and only lasting a few years, instead of the 10 years you were promised, it's not a great situation to be in.

Immersion heater elements aren't so expensive, but it's a real hassle getting them replaced.

Then there's the loss of efficiency.

A scale fouled boiler or heater could be operating at only 50% efficiency.

That means it takes twice as much energy to heat the water to the temperature you want.

Your energy bills could be almost double what they should be just because you live in a hard water area and don't contraol the scale build up.

So what can you do about boiler scale?

The obvious thing is to buy a chemical boiler descaler. But they have to be introduced into the heating system, and usually require you to drain down the plumbing, then fully flush it too afterwards.

It's all a bit of a faff, and quite daunting for most people to do themselves.

A much smarter method is to install a scale conditioning filter such as one of our OneFlow range.

These will strip out existing scale, and then prevent more scale forming in the future.

You'll only need to call the plumber in once to install the system, which is a simple "water in/water out" arrangement.

The beauty of the OneFlow TAC media system is that it treats all the water, including the radiators, and only needs a cartridge change once a year - or longer.

No chemicals are added, so the water is drinkable too.

How does OneFlow work?

Nucleation sites on TAC mediaIt uses a process called template-assisted crystalisation, or TAC.

This is where the dissolved minerals calcium carbonate (CaCO3), magnesium carbonate (MgCO3), and bicarbonate (HCO3), combine into microscopic crystals on the TAC media's nucleation sites.

These microscopic crystals then detach from the media and flow freely through the plumbing system instead of creating a hard scale.

You can maintain it yourself

Changing the cartridge or media is a simple job that you can do yourself - no need to call the plumber back.

Better still, it will probaby only need to be done once a year - no need to feed the system with salt pellets every week.

There's no electricity supply, no brine tank, and no backwashing requiring a 2 hour shutdown.
