Re: Saltless Water Softerner?

So I tried scaling up my kettle, by repeatedly boiling water. Every time it evaporated enough, I would top it up.


Now, I have a supersaturated mixture - with limescale clumps floating at the top

Re: Saltless Water Softerner?

I cannot imagine the CO2 systems working for hot water -as the temperature rises hydrogen carbonate is converted to carbonate and the extra CO2 gas will also escape.
Reverse osmosis ( a very fine filter) will work as would (for "temporary" hardness which is probably the problem here) a sacrificial tank where the water is preheated. You could also try a ion exchange de-ioniser that is used for lab-supply water -at high flow rate to make it deliberately less efficient?

I descaled my keetle two days ago, but as soon as it's scaled again, I'll fill it with sodastream water and leave it overnight... if it works, that's as good a proof as any

Good idea. I'll be interested in your results, might even try it myself as well. What exactly it will prove I'm not sure, with the concentrations involved, but it will certainly be interesting.

So did you ever get round to trying out the fizzy water as a descaler?

It had no effect at all when I tried it, so I'm inclined to stick with my sceptical view that it's just a rip-off based on poorly explained pseudo-science.
