摘要： A water heater system includes a primary heat exchanger including a tank and at least one flue, and a secondary heat exchanger including a core and a flue gas flow path. The water heater is operable in a heating mode in which a combustor produces hot flue gas and a water pump flows water through the core of the secondary heat exchanger and into the tank, and in a non-heating mode in which the combustor and the water pump are inoperative. The flue gas flows from the combustor through the at least one flue to heat the water in the tank and then through the flue gas flow path to heat water in the core before being exhausted.

摘要： Methods and systems for determining a possible leak within a gas water heater. One system is a gas water heater including a blower and an electronic processor. The electronic processor is configured to activate the blower for a predetermined amount of time, receive, during the predetermined amount of time, a measurement of a characteristic of the blower, perform a comparison between the measurement and a predetermined characteristic threshold, and determine, based on the comparison, that a blockage is present within the water heater. The electronic processor is further configured to output a notification in response to determining the blockage is present.

摘要： A water heating system including a tank, a first heating element, a second heating element, a first temperature sensor, a second temperature sensor, a controller having an electronic processor and a memory. The controller is configured to determine an output temperature setpoint, determine whether a period of expected high water demand is approaching, and in response to determining that the period of expected high water demand is approaching, activate the second heating element. The controller is further configured to deactivate the second heating element when a second temperature sensed by the second temperature sensor crosses a second temperature threshold, activate the first heating element when the second temperature crosses the second temperature threshold, and deactivate the first heating element. Wherein the first temperature threshold is lower than the second temperature threshold and the first and second temperature thresholds are higher than the output temperature setpoint.

摘要： An electric motor having a shaft access cover. The electric motor includes a housing that defines an aperture, a stator fixed relative to the housing, a shaft rotatable relative to the housing so the aperture provides access to an end portion of the shaft, and a rotor connected to the shaft for rotation therewith relative to the stator. The end portion of the shaft has a surface adapted for engagement by a tool so a load drivingly connected to the electric motor can be manipulated with respect to the electric motor. The shaft access cover is attachable to the housing for pivotable movement between an unlocked position and a locked position where the shaft access cover substantially covers the aperture. The pivotable movement between the locked and unlocked positions includes less 360 degrees of pivotable movement.
