You are lucky to have soft water there mate..
My gran gave me a kettle about 30yrs ago to take to bath when I started on a road job..
That had an exposed element in the bottom.the kettle was 8yr old and the element looked brand new..
Within 2 weeks the element was white with limescale..the difference in water is crazy..
You can definitely taste the difference in soft and hard water especially in tea..
