Disaggregation of gas load to determine gas appliance performance

A headend device, comprising:

• a processor;
• a network connection;
• and
• one or more computer-readable media storing computer-executable instructions that, when executed by the processor, configure the headend device to perform operations comprising:
• obtaining a first flowrate of gas;
• disaggregating the first flowrate of gas to obtain a second flowrate of gas corresponding to an appliance having a generally fixed-rate of gas consumption, wherein the disaggregating comprises:
• anticipating an increase in consumption of the appliance, wherein the increase in consumption is due to an ageing process of the appliance;
• and
• recognizing gas consumption of the appliance in the disaggregation based in part on the anticipated increase in consumption of the appliance due to the ageing process;
• comparing the second flowrate of gas corresponding to the appliance to a historical gas consumption by the appliance;
• determining, based at least in part on the comparing, that performance of the appliance has changed over time;
• generating a notification, based at least in part on the determining that performance of the appliance has changed over time;
• and
• transmitting the notification to another device.
