Abstract
A water heater performance monitoring device for monitoring whether a water heater is functioning optimally or whether it requires service. The device uses maximum heating rates taken from a plurality of measured heating rates to determine if the performance of the water heater has degraded from a threshold performance level. A water heater performance monitoring device can reduce the number of false alarms that occur regarding the need for water heater service by filtering out temporary factors, lasting less than a time cycle, which affect heating rate of water in the water heater. This can save users time and money by reducing unnecessary water heater inspections.
