Hows that work then?
I fitted one where two wires are rapped around the incoming supply. I was surprised it worked, and continues to do so 20yrs later. Doesnt get rid, just stops it furring up the kettle as much
we bought a water softener, "uses salt" absolutley no lime scale in 16 years....salt was about a 5er a bag......
There's an inline scale reducer in our place. It's just snake oil!! Supposedly magnetises the water molecules, but no visible benefit until we fitted a proper ion-exchage resin based softener. A sacrificial anode would be consumed very quickly, so being sceptical.
The sales blurb for the ActivFlo device goes like: "In hard water, there are calcium carbonate crystals." Uh, oh, I smell misinformation!! There might be dissolved calcium compounds, but not crystals.
There is a sacrificial anode inside, it replaces the calcium with zinc
Some are better than others, these are pretty good but cost £200
Magnetic ones don't work, electrolytic ones do
got any recommendations of which one to get?
oh and the welding is lovely. Is that by man or machine?
You’re right.Its manually welded, and actually by industrial standards is pretty average really, no doubt welded by a production welder who probably does little else but make one or a small range of very similar products
I’ll take the calcium over the zinc in my water thanks.
Same with any filtered/softened water.

The numbers don't seem to add up. As an example, using the measured hardness level of our incoming mains water supply, which is 400ppm. That's 400mg/litre of calcium and/or magnesium ions. Based on figures from ccwater.org.uk, a typical 4 person household uses around 450 litres per day, equating to 180g of calcium and/or magnesium ions, per day. How much zinc is there in these ActivFlo things?
