When I said boil the kettle, I did not mean keeping one going all the time with boiling water in it. That would need a stove or aga which I don't have. A kettle is used. an electric kettle that you fill with cold water, close the lid, press a button and 3 minutes later roughly you have boiling water. It turns off automatically.
I also don't do percolator coffee, it is awful. The instant coffee we have here is much better than that you get (from what I have read). So adding hot water to a whiskey and lemon mixture is not difficult (on this side of the pond).
I have one of these. They are found in pretty much every household in Europe.
