*smacks self upside head* duh! of course!

Now - for the New England Handyman way to boil water...

to boil , get sufficient copper tubing to extend from the tap to a coil above the burner of the cooker, back across the room to the tap, wrapping it around the tap as many times as possible before ending with it pointing into the sink. turn on a slow flow of water, turn on the burner. In a positive feedback loop the water will be heated, first by the burner, then by the heat exchange of the coil about the tap and also by heat conducted through the copper piping until it eventually boils.
