Abstract: The disclosure reveals a system for detecting moisture or water in a particular location. The system may incorporate a moisture detector having a control module connected to an appliance, a moisture detection circuit connected to the control module, and a voltage source connected to the moisture detection circuit and to the control module. The voltage source and the moisture detection circuit may provide voltage levels to the control module when the moisture detection circuit detects dry or wet conditions, or conditions between those conditions. A voltage level to the control module may indicate whether the appliance, such as a water heater, a washing machine, or a dish washer, has a leak. If the leak is deemed by a voltage level from the circuit to be worthy of concern, then a display, an alarm, message, or other notice mechanism may indicate an issue or what action needs to be taken.

Abstract: A gas valve assembly configured to operate without a pilot assembly is disclosed. In an illustrative embodiment, a servo valve actuates a diaphragm valve to selectively allow for fluid coupling of a gas inlet and gas outlet. The diaphragm valve may be a normally closed valve that opens in response to a pneumatic force resulting from the opening of the servo valve.

Abstract: A heat sink assembly draws heat away from the cold junction of a thermopile element to increase the thermopile's power output. In one example, the heat sink assembly includes a first thermally conductive securing mechanism, a second thermally conductive securing mechanism, and a thermally conductive tube having a first end and a second end. The first end of the thermally conductive tube is secured between the first securing mechanism and the second securing mechanism. In some cases, the first end of the thermally conductive tube may include a flanged region adjacent the first end with at least part of the flange region secured between the first securing mechanism and the second securing mechanism. The flange may help with heat transfer to the thermally conductive tube.

Abstract: A device for igniting a pilot light for a heating appliance or for re-igniting the pilot. The device may monitor a thermopile at the pilot to determine if the pilot is lit and, if not, attempt to relight it. If the device fails to relight the pilot, it may continue attempting to relight the pilot until the stored energy is nearly depleted. Before the stored energy is depleted, the device may send a message indicating a failure to relight. The last of stored energy may alert a homeowner with an alarm that the appliance control has shut down and the pilot could not be relit. If the amount of energy stored drops below a specified threshold and the device successfully lights the pilot, it may restore the control to normal operation, and replenish the stored energy. The device may do a standing pilot or an intermittent pilot.

Abstract: A system for heating water to improve safety and efficiency. The system may have normal operation measured in time. After a time of normal operation, a water temperature setpoint may be checked. If the setpoint is not at a certain level, normal operation may continue. If the setpoint is within the certain level, water temperature may be measured. If the water temperature is less than a desired level, one or more draws of water may be measured for a preset temperature drop. If the draws do not meet the temperature drop, a return to check the setpoint may be made. If the draws meet the temperature drop, the setpoint may be reduced and a time of normal operation may be measured to determine whether a burn cycle occurs within the time. If not, normal operation may continue; but if so, a return to check the setpoint may be made.

Abstract: A system and approach for developing a periodic water usage profile and demand for controlling a water heater. A mode may be selected for demand for a certain amount of water of a particular temperature range to be available for use from the water heater. Data on hot water usage may be collected and the usage profile and demand may be calculated from the data. The water heater may be programmed to operate in a certain fashion based on the usage profile and demand. A control knob may be on the water heater control to select a particular demand. Control of the water heater may be operated from a remote device connected in a wireless or wired fashion. An optimization program may be implemented in the control of the water heater for achieving one or more beneficial goals related to water heater performance and hot water production.
