We have recently fitted an instant hot water tap over our sink - one more appliance off the bench, the jug can move to the caravan! It makes a good cuppa tea http://www.insinkerator.co.nz/store/instant-hot-water-taps/gn1100/
I did put a timer on the boiling water tap so I was not paying for it to be heated overnight. It came on at 0600 and off at 2000. Over a year a big saving in electricity.Gert
