Bottled water that doesn't have lime in it

What hard water looks and tastes like

• Hard water looks and smells the same as soft water.
• Its high mineral content gives it a better taste than soft water and can offer more health benefits.

Why we don't soften hard water

• There are no health risks involved in drinking and using hard water
• Softening water removes healthy minerals from hard water
• The law doesn't require us to remove hardness from drinking water
• Chemically softened water may not be suitable for everyone to drink, such as infants or at-risk groups.
• Hard water can coat the inside of lead pipes or fittings, preventing lead from getting into your drinking water.

Bottled water will not cause limescale build ups anywhere close to the rate you get from tap water in a hard water area.

Replace your kettle and use bottled water, you'll be fine

limescale is calcium carbonate. Not only is it not harmful, it’s essential for human existence.

The money and energy required to remove it from the public water supply would be astronomical, and utterly pointless.

People use water softener to protect the long term life of appliance, pipes and heating systems. I have it for that very reason. But I wouldn't drink softened water if you paid me.

It may not be for the tea people put in water softener systems.

Limescale buildup on the coil and immersion rod in the copper cylinder and pipes cuts down the efficiency of the system. Electric shower units also need replacing more frequently than non limescale areas. I'm living in North Offaly an area riddled with limescale.

Flower vases if not cleaned and scrubbed after use will have a film of limecale after 2 or 3 weeks of not fully cleaning.

The thing you seem to be missing is that when you boil hard water the lime is left behind in your kettle.

get four or five lemons, cut them in half, put them in the kettle and boil it a couple of times, the limescale will lift right off

OP, have you considered moving to an area with less lime in the water supply?

For example, the bulk of the supply to the county of Dun Laoghaire-Rathdown is soft(er) water. To the extent that the residents do not need to use salt in their dishwashers.

It's down to geography and geology - the determining factor is which reservoir or river supplies the treatment facility that pumps water to your house.

OP, sounds like this is what you want:
