摘要： The present invention describes a novel outdoor enclosure for circulating pumps for outdoor tankless heaters, outdoor boilers and other outdoor applications. The enclosure includes a body and a cover with the body attaching to the circulator motor. When closed, the enclosure keeps rainfall and other contaminates from entering the wiring space within the enclosure and the circulator motor. The body of the enclosure has multiple ports for electrical wiring inputs for power and for controls connections which can be made with flexible cords and/or hardwires. The outdoor enclosure can be equipped with a terminal strip to simplify wiring and/or with a timer to control when the circulator operates. To avoid problems associated with freezing, the enclosure may include a thermal device that turns the circulator on if temperatures drop. To secure the cover to the body, fastener tabs are included that can accept a screw or lock.

摘要： A water heater system includes a controller configured to integrate control of both recovery and recirculation operations of a recovery pump and a recirculation pump. As such, a separate device, installation location, and power source (e.g., available outlet) is not needed with the controller. Because a single controller is configured to control both recovery and recirculation operations, additional control functions are available. The controller may be in communication with an internal controller of the water heater and configured to receive an error notification upon abnormal operation of the water heater. The controller can stop recovery and recirculation operations in response to an error notification, unlike with traditional water heating systems which may otherwise continue to function. The recovery and recirculation operations are based on a setpoint temperature of the water heater such that changes made to the setpoint temperature will automatically adjust in the recovery and recirculation operations.

摘要： A hot water circulation system comprises a water heater having a cold-water inlet and a hot water outlet. A water pump circulates water through the water heater to produce hot water. The hot water is circulated to a thermal bypass valve, which is configured to close when hot water contacts a heat activated seal. A bypass circuit is coupled between the hot water outlet and the cold water inlet of the water heater. The bypass circuit prevents hot water from circulating from the hot water outlet to the cold-water inlet when the thermal bypass valve is open and promotes circulating hot water from the hot water outlet to the cold water inlet when the thermal bypass valve is closed. Upon a temperature sensor sensing hot water entering the cold-water inlet, the water heater turns of the water pump.
