R D S expressed precisely :
Yes, I have a collection of kettles at work that we've mothballed for one
reason or another.
Keep meaning to chuck em but you know how it is....

When we replace such small items, we keep the old version as a spare,
unless it is completely dead. We have spare iron, toaster, kettle,
coffee maker etc.. When a present item is due replacement, it will go
in the spares cupboard, and the older version will be disposed of.
