Abstract: A water sensor and alarm system for storage water heaters comprising an alarm housing, embedded battery, annunciator, and two bottom exposed fluid sensors separated by a stand-off. The system is designed for prompt owner notification when fluid is detected adjacent to a hot water heater tank. Notification is audible, and optionally may be in the form of remote notification, such as but not limited to a signal transmitted to the home security device connected to a 24-hour security monitoring network, or a smart phone, tablet, or other smart device. The alarm housing can be easily and quickly mounted to the side of the water heater tank. Ultra low power consumption is an important benefit provided by the alarm system, which continues during low battery warnings and water detection alarming. Also, the audible alarm may optionally include a boost circuit to amplify annunciator loudness, but at a tradeoff with conserving power.
