> it might even get to boiling if it can boil water, can't it be used to generate electricity? What makes it "spent"?

  You could, but it would be less than 10W of electricity, so not enough to power a lightbulb. The water tank is insulated, so the water just heats up slowly until it reaches boiling point. That doesn't mean it's a powerful heat source.

    So basically if you use up all the hot water in your shower you are going to be in hot water!

    Ah I see, so it's about the rate of heating more than the amount of heat it can potentially generate. That makes sense, thanks.
