> Not sure why your dishwasher changes anything, they normally run off cold water and use their own heaters.
For North America at least, this is not true. Dishwashers are hooked up to the hot water supply[1] (and it's a good idea to run your sink tap hot to "prime" the hot water for the dishwasher).
They _also_ use built in heating elements to keep the water hot, and to dry the dishes, though.
