This is a gimmick built to sell houses, a cool one, but only in hot
climates does it make much difference.  In cooler climates the heat
from the standing water in the pipes just makes the furnace run less,
thus the savings are a wash.

those have been around for at least 20 years.  As most of them are
electric, not natural gas, your going to pay more money for heating
water with a bunch of those than with a central gas water heater.
