We are in hard water area and getting bored of having to de scale the
kettle! I also wonder what the inside of the washing machine must look
like but perhaps I have been made paranoid by those calgon adverts?
fitting a water softener will not stop your kettle scaling up -
softened water is neither pleasant nor good to drink due to its salt
content.

It has no salt: just sodium carbonate.

Whatever, it's not healthy to drink. Or am I wrong about that?
