Lets put it this way - before the condensing tumble dryer I would have to clean and descale her steam iron monthly and replace it after about 3 years (in East Sussex/Kent a lot of our water comes from the chalk, so is hard). Since the condensing tumble dryer and using the condensed water I clean her steam iron about once pa and have not replaced it in about 15 years! I rest my case!!
If you'd like to collect the bits for the rack, you're welcome to them - 8 miles from J10 M20 towards Tenterden.
Or install a water softener ... operates on the whole system apart from the sink taps.
