Integrated uninterruptible power supplies for appliances

An appliance system comprising:

• a housing;
• an appliance system disposed, at least in part, within the housing;
• an energy metering module configured to detect an energy consumption of the appliance system and output energy data;
• a switch coupled to the appliance system, wherein the switch operates between a first position during normal operations and a second position during an outage;
• a primary power source coupled to the switch, wherein the primary power source is configured to provide primary power to the appliance system through the switch during the normal operations;
• an uninterruptible power supply (UPS) coupled to the switch, wherein the UPS is configured to provide reserve power to the appliance system through the switch during the outage;
• and
• a controller in communication with the energy metering module and the UPS, the controller being configured to:
• determine that an outage is occurring or will occur based on data received from the energy metering module;
• and
• receive sensor data from one or more sensors associated with an appliance;
• in response to determining, based on the sensor data, that the appliance is operating, output instructions for the UPS to operate for a predetermined time.

A water heater comprising:

• a housing;
• a heating system disposed within the housing, wherein the heating system is configured to heat a fluid;
• an energy metering module configured to (i) detect an energy consumption of the water heater and (ii) output energy data;
• a switch coupled to the heating system, wherein the switch operates between a first position during normal operations and a second position during an outage;
• a primary power source coupled to the switch, wherein the primary power source is configured to provide primary power to the heating system through the switch during the normal operations;
• an uninterruptible power supply (UPS) coupled to the switch, wherein the UPS is configured to provide reserve power to the heating system through the switch during the outage;
• and
• a controller in communication with the energy metering module and the UPS, the controller being configured to:
• determine that an outage is occurring based on data received from the energy metering module;
• and
• determine that an amount of available reserve power is below a predetermined threshold;
• and
• output instructions for purging water from pipes in fluid communication with the water heater, thereby preventing freezing of water within the pipes.
