Abstract: Two water heaters may be installed in series at a customer location, such that an output of a first (or storage) water heater is coupled to the input of a second (or primary) water heater, the output of which provides hot water to the customer location. During normal operation, only the primary water heater may actually heat water for use at the customer location.
