The problem here is that the hot water pipe from the house water heater
seems to go under the slab foundation, and seems to be uninsulated, and the
dishwasher is about 30 feet from the water heater. So even if I let the
water get hot in the pipe first, it won't still be hot each time the
dishwasher wants water from it.
