Abstract:
1. A water heating system comprising: a hybrid water heater including a tank body and a heat pump, the heat pump being located in a conditioned space proximate the tank body and receiving warm air from a first remote location and exhausting air cooled by the heat pump into a second remote location; a shroud configured to enclose the heat pump; ductwork extending from the hybrid water heater to the first and second remote locations spaced from the hybrid water heater; a collar surrounding and extending outwardly from a vent of the shroud, the collar being configured to couple to the ductwork; a boost fan; and an airflow sensor configured to detect whether the heat pump is in operation, wherein the boost fan is energized to move air through the ductwork between the heat pump and the first and second remote locations in response to the airflow sensor's detection that the heat pump is in operation, and wherein the boost fan is sized so that once energized the boost fan provides a net-zero pressure increase through the ductwork at the heat pump so that a fan of the heat pump is not impacted.
