Being a 1500W kettle, it should take about 4.5 -> 5.0 minutes or so.

We purchased the cheapest UK one we saw (a mere UK 4.95 !!). It is only a 2200W kettle, yet that still makes it 50% faster than the best 1500W models over here.

Now that we've proven the concept etc.. we plan to pick up a 3000W kettle with detached contact base (a nearly-essential feature we were unaware of at the time) on the next trip over.

Cheers
