摘要：A water heater performance monitoring device for monitoring whether a waterheater 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 theperformance of the water heater has degraded from a threshold performance level. Awater heater performance monitoring device can reduce the number of false alarms thatoccur 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. Thiscan save users time and money by reducing unnecessary water heater inspections.
